Enter your ISP Username and ISP Password.2. Click Connect to the Internet.

Administrator’s Handbook48A brief message is displayed while the Gateway attempts to establish a connection. 3. When the connection succeeds, your browser will display your Service Provider’s home page.If you encounter any problems connecting, refer to the chapters “Basic Troubleshooting” on page 193 or “Advanced Troubleshooting” on page 207.

49Link: LAN* Enable Interface: Enables all LAN-connected computers to share resources and to connect to the WAN. The Interface should always be enabled unless you are instructed to disable it by your Service Provider dur-ing troubleshooting.* IP Address: The LAN IP Address of the Gateway. The IP Address you assign to your LAN inter face must not be used by another device on your LAN network.* IP Netmask: Speciﬁes the subnet mask for the TCP/IP network connected to the virtual circuit. The sub-net mask speciﬁes which bits of the 32-bit binary IP address represent network information. The default subnet mask for most networks is 255.255.255.0 (Class C subnet mask.)* Restrictions: Speciﬁes whether an administrator can open a Web Administrator or Telnet connection to the Gateway over the LAN interface in order to monitor and conﬁgure the Gateway. On the LAN Interface, you can enable or disable administrator access. By default, administrative restrictions are turned off, meaning an administrator can open a Web Administrator or Telnet connection through the LAN Interface.• Advanced: Clicking on the Advanced link displays the Advanced LAN IP Interface page.

Administrator’s Handbook50•IGMP Forwarding: The default setting is Disabled. If you check this option, it will enable Internet Group Management Protocol (IGMP) multicast forwarding. IGMP allows a router to determine which host groups have members on a given network segment. See “IGMP (Internet Group Management Protocol)” on page 100 for more information.•RIP Send Mode: Speciﬁes whether the gateway should use Routing Information Protocol (RIP) broad-casts to advertise its routing tables to other routers on your network. You may choose from the following protocols:• RIP-1: Routing Information Protocol version 1• RIP-2: RIP Version 2 is an extension of the original Routing Information Protocol (RIP-1) that expands the amount of useful information in the RIP packets. While RIP-1 and RIP-2 share the same basic algo-rithms, RIP-2 supports several new features, including inclusion of subnet masks in RIP packets and implementation of multicasting instead of broadcasting (which reduces the load on hosts which do not support routing protocols.• RIP-1 compatibility: Compatible with RIP version 1• RIP-2 with MD5: MD5 authentication is an extension of RIP-2 that increases security by requiring an authentication key when routes are advertised.• RIP MD5 Key: Secret password when using RIP-2 with MD5. •RIP Receive Mode: Speciﬁes whether the Gateway should use Routing Information Protocol (RIP) broadcasts to update its routing tables with information received from other routers on your network. The protocol choices are the same as for the RIP send mode.•Proxy ARP: Speciﬁes whether you want the Gateway to respond when it receives an address resolution protocol for devices behind it. This is a way to make a computer that is physically located on one net-work appear to be part of a different physical network connected to the same Gateway. It allows you to hide a computer with a public IP address on a private network behind your Gateway, and still have the computer appear to be on the public network “in front of” the Gateway.•Static Client Address Translation: If you check this checkbox, this feature allows a statically addressed computer whose IP address falls outside of the LAN subnet(s) to simply plug in and get online without any manual conﬁguration on either the host or the Motorola Netopia® Gateway. If enabled, statically addressed LAN hosts that have an address outside of LAN subnets will be able to communicate via the Router’s WAN interface to the Internet. Supported static IP address values must fall outside of the Router's LAN subnet(s).• IP Subnets: The IP Subnets screen allows you to conﬁgure up to seven secondary subnets and their DHCP ranges, by entering IP address/subnet mask pairs:

51☛ Note: You need not use this screen if you have only a single Ethernet IP subnet.This screen displays seven rows of editable columns. All seven row labels are always visible, regardless of the number of subnets conﬁgured.•To add an IP subnet, select one of the rows, and click the Edit button. Check the Enabled checkbox and click the Submit button.The screen expands to allow you to enter subnet information. If DHCP Server (see below) is not enabled, the DHCP Start Address and DHCP End Address ﬁelds do not appear.•Enter the Router’s IP address on the subnet in the IP Address ﬁeld and the subnet mask for the subnet in the Netmask ﬁeld.•Enter the DHCP Start Address and End Address of the subnet range in their respective ﬁelds.Ranges cannot overlap and there may be only one range per subnet.•Click the Submit button. •When you are ﬁnished adding subnets, click the Alert icon at the upper right, and in the resulting page, click the Save and Restart link.To delete a conﬁgured subnet, set both the IP address and subnet mask values to 0.0.0.0, either explicitly or by clearing each ﬁeld and clicking the Submit button to commit the change.☛ NOTE: All additional DHCP ranges use the global lease period value. See page 52.

Administrator’s Handbook52• DHCP Server: Your Gateway can provide network conﬁguration information to computers on your LAN, using the Dynamic Host Conﬁguration Protocol (DHCP). If you already have a DHCP server on your LAN, you should turn this service off. If you want the Gateway to provide this service, click the Server Mode pull-down menu, choose Server, then con-ﬁgure the range of IP addresses that you would like the Gateway to hand out to your computers. You can also specify the length of time the computers can use the conﬁguration information; DHCP calls this period the lease time.Your Service Provider may, for certain services, want to provide conﬁguration from its DHCP servers to the computers on your LANs. In this case, the Gateway will relay the DHCP requests from your computers to a DHCP server in the Service Provider's network. Click the relay-agent and enter the IP address of the Service Provider's DHCP server in the Server Address ﬁeld. This address is furnished by the Service Provider.☛ NOTE:The Relay-agent option only works when NAT is off and the Gateway is in router mode.

53Wireless(supported models)If your Gateway is a wireless model (such as a 3347W) you can enable or disable the wireless LAN (WLAN) by clicking the Wireless link. Wireless functionality is enabled by default.If you uncheck the Enable Wireless checkbox, the Wireless Options are disabled, and the Gateway will not provide or broadcast any wireless LAN services.SSID (Network ID): The SSID is preset to a number that is unique to your unit. You can either leave it as is, or change it by entering a freeform name of up to 32 characters, for example “Ed’s Wireless LAN”. On client PCs’ software, this might also be called the Network Name. The SSID is used to identify this particular wire-less LAN. Depending on their operating system or client wireless card, users must either:•select from a list of available wireless LANs that appear in a scanned list on their client•or, if you are in Closed System Mode (see Enable Closed System Mode below), enter this name on their clients in order to join this wireless LAN.The pull-down menu for enabling Privacy offers four settings: WPA-802.1x, WPA-PSK, WEP - Automatic, and Off - No Privacy. WEP-Manual is also available on the Advanced Conﬁguration Options page. See “Pri-vacy” on page 54.☛ NOTE:On the 2200-Series Gateways, WEP-Manual privacy is enabled by default. Use the Motorola Netopia® Installation Wizard on the accompanying Motorola Netopia® CD to generate WEP keys for connecting wireless client computers.

Administrator’s Handbook54Privacy•Off - No Privacy provides no encryption on your wireless LAN data.•WPA-802.1x provides RADIUS server authentication support.•WPA-PSK provides Wireless Protected Access, the most secure option for your wireless network. This mechanism provides the best data protection and access control. The Pre Shared Key is a passphrase shared between the Router and the clients and is used to gener-ate dynamically changing keys. The passphrase can be 8-63 characters or up to 64 hex characters. It is recommended to use at least 20 characters for best security.•WEP - Automatic is a passphrase generator. You enter a passphrase that you choose in the Pass-phrase ﬁeld. The passphrase can be any string of words or numbers. You can provide a level of data security by enabling WEP (Wired Equivalent Privacy) for encryption of net-work data. You can enable 40-, 128-, or 256-bit WEP Encryption (depending on the capability of your cli-ent wireless card) for IP trafﬁc on your LAN.

55You select a single key for encryption of outbound trafﬁc. The WEP-enabled client must have an identical key of the same length, in the identical slot (1 – 4) as the Gateway, in order to successfully receive and decrypt the trafﬁc. Similarly, the client also has a ‘default’ key that it uses to encrypt its transmissions. In order for the Gateway to receive the client’s data, it must likewise have the identical key of the same length, in the same slot. For simplicity, a Gateway and its clients need only enter, share, and use the ﬁrst key.Click the Submit button. The Alert icon appears. Click the Alert icon, and then the Save and Restart link.

Administrator’s Handbook56AdvancedIf you click the Advanced link, the advanced 802.11 Wireless Settings page appears.Note: This page displays different options depending on which form of Privacy or other options you have enabled.You can then conﬁgure:Operating Mode: The pull-down menu allows you to select and lock the Gateway into the wireless trans-mission mode you want. For compatibility with clients using 802.11b (up to 11 Mbps transmission) and 802.11g (up to 20+ Mbps), select Normal (802.11b + g). To limit your wireless LAN to one mode or the other, select 802.11b Only, or 802.11g Only. ☛ NOTE:If you choose to limit the operating mode to 802.11b or 802.11g only, clients using the mode you excluded will not be able to connect.Default Channel: on which the network will broadcast. This is a frequency range within the 2.4Ghz band. Channel selection depends on government regulated radio frequencies that vary from region to region. The widest range available is from 1 to 14. However, in North America only 1 to 11 may be selected. Europe,

57France, Spain and Japan will differ. Channel selection can have a signiﬁcant impact on per formance, depending on other wireless activity close to this Gateway. Channel selection is not necessary at the client computers; the clients will scan the available channels seeking access points using the same SSID as the client.AutoChannel Setting: For 802.11G models, AutoChannel is a feature that allows the Motorola Netopia® Gateway to determine the best channel to broadcast automatically.Three settings are available from the pull-down menu: Off-Use default, At Startup, and Continuous.•Off-Use default is the default setting; the Motorola Netopia® Gateway will use the conﬁgured default channel selected from the previous pull-down menu.•At Startup causes the Motorola Netopia® Gateway at startup to brieﬂy initialize on the default channel, then perform a full two- to three-second scan, and switch to the best channel it can ﬁnd, remaining on that channel until the next reboot.•Continuous performs the at-startup scan, and will continuously monitor the current channel for any other Access Point beacons. If an Access Point beacon is detected on the same channel, the Motorola Netopia® Gateway will initiate a three- to four-minute scan of the channels, locate a better one, and switch. Once it has switched, it will remain on this channel for at least 30 minutes before switching again if another Access Point is detected.Enable Closed System Mode: If enabled, Closed System Mode hides the wireless network from the scan-ning features of wireless client computers. Unless both the wireless clients and the Router share the same SSID in Closed System mode, the Router’s wireless LAN will not appear as an available network when scanned for by wireless-enabled computers. Members of the Closed System WLAN must log onto the Router’s wireless network with the identical SSID as that conﬁgured in the router.Closed System mode is an ideal way to increase wireless security and to prevent casual detection by unwanted neighbors, ofﬁce users, or malicious users such as hackers.If you do not enable Closed System Mode, it is more convenient, but potentially less secure, for clients to access your WLAN by scanning available access points. You must decide based on your own network requirements.About Closed System ModeEnabling Closed System Mode on your wireless Gateway provides another level of security, since your wire-less LAN will no longer appear as an available access point to client PCs that are casually scanning for one.Your own wireless network clients, however, must log into the wireless LAN by using the exact SSID of the Motorola Netopia® Gateway.In addition, if you have enabled WEP encryption on the Motorola Netopia® Gateway, your network clients must also have WEP encryption enabled, and must have the same WEP encryption key as the Motorola Netopia® Gateway.Once the Motorola Netopia® Gateway is located by a client computer, by setting the client to a matching SSID, the client can connect immediately if WEP is not enabled. If WEP is enabled then the client must also have WEP enabled and a matching WEP key. Wireless client cards from different manufacturers and different operating systems accomplish connecting to a wireless LAN and enabling WEP in a variety of ways. Consult the documentation for your particular wire-less card and/or operating system.

Administrator’s Handbook58☛ NOTE: While clients may also have a passphrase feature, these are vendor-speciﬁc and may not nec-essarily create the same keys. You can passphrase generate a set of keys on one, and manu-ally enter them on the other to get around this.Block Wireless Bridging: Check the checkbox to block wireless clients from communicating with other wireless clients on the LAN side of the Gateway.•WEP - Manual allows you to enter your own encryption keys manually. This is a difﬁcult process, but only needs to be done once. Avoid the temptation to enter all the same characters.Encryption Key Size #1 – #4: Selects the length of each encryption key. The longer the key, the stronger the encryption and the more difﬁcult it is to break the encryption.

59Encryption Key #1 – #4: The encryption keys. You enter keys using hexadecimal digits. For 40/64bit encryption, you need ten digits; 26 digits for 128bit, and 58 digits for 256bit WEP. Hexadecimal characters are 0 – 9, and a – f. Examples:•40bit: 02468ACE02•128bit: 0123456789ABCDEF0123456789•256bit: 592CA140F0A238B0C61AE162F592CA140F0A238B0C61AE162F21A09CUse WEP encryption key (1 – 4) #: Speciﬁes which key the Gateway will use to encrypt transmitted trafﬁc. The default is key #1.You disable the wireless LAN by unchecking the Enable Wireless checkbox, clicking the Submit button, fol-lowed by the Save and Restart link.WPA Version AllowedIf you select either WPA-802.1x or WPA-PSK as your privacy setting, the WPA Version Allowed pull-down menu appears to allow you to select the WPA version(s) that will be required for client connections. Choices are: •WPA Version 1 and 2, for maximum interoperability,•WPA Version 1 Only, for backward compatibility,•WPA Version 2 Only, for maximum security.All clients must support the version(s) selected in order to successfully connect.Multiple SSIDsThe Multiple Wireless SSIDs feature allows you to add additional network identiﬁers (SSIDs or Network Names) for your wireless network.To enable Multiple Wireless SSIDs, click the Multiple SSIDs link.When the Multiple Wireless SSIDs screen appears, check the Enable SSID checkbox for each SSID you want to enable.

Administrator’s Handbook60The screen expands to allow you to name each additional Wireless ID, and specify a Privacy mode for each one.

61Privacy modes available from the pull-down menu for the multiple SSIDs are: WPA-PSK, WPA-802.1x, or Off-No Privacy. WEP can also be selected on the additional SSIDs as long as it is not used on the primary SSID. WEP can only be used on one SSID, so any others will not have WEP available.These additional Wireless IDs are “Closed System Mode” Wireless IDs that will not be shown by a client scan, and therefore must be manually conﬁgured at the client. In addition, wireless bridging between clients is disabled for all members of these additional network IDs.Click the Submit button.After your ﬁrst entry, the Alert icon will appear in the upper right corner of your screen. When you are ﬁnished adding SSIDs, click the Alert icon, and Save your changes and restart the Gateway.

Administrator’s Handbook62WiFi MultimediaWiFi Multimedia is an advanced feature that allows you to prioritize various types of data travelling over the wireless network. Certain types of data that are sensitive to delays, such as voice or video, must be priori-tized ahead of other, less delay-sensitive types, such as email. WiFi Multimedia currently implements wireless Quality of Service (QoS) by transmitting data depending on Diffserv priority settings. These priorities are mapped into four Access Categories (AC), in increasing order of priority: •Background (BK), •Best Effort (BE), •Video (VI), and •Voice (VO). It requires WiFi Multimedia (WMM)-capable clients, usually a separate feature enabled at the client network settings, and client PC software that makes use of Differentiated Services (Diffserv). Refer to your operat-ing system instructions for enabling Diffserv QoS..When you click the WiFi Multimedia link the WiFi Multimedia page appears.To enable the WiFi Multimedia custom settings, select Diffserv from the pull-down menu.

63The screen expands.Router EDCA Parameters (Enhanced Distributed Channel Access) govern wireless data from your Gate-way to the client; Client EDCA Parameters govern wireless data from the client to your Gateway.☛ NOTE:It is not recommended that you modify these settings without direct knowledge or instructions to do so. Modifying these settings inappropriately could seriously degrade network perfor-mance.•AIFs: (Arbitration Interframe Spacing) the wait time in milliseconds for data frames.•cwMin: (Minimum Contention Window) upper limit in milliseconds of the range for determining initial ran-dom backoff. The value you choose must be lower than cwMax.•cwMax: (Maximum Contention Window) upper limit in milliseconds of the range of determining ﬁnal ran-dom backoff. The value you choose must be higher than cwMin.•TXOP Limit: Time interval in microseconds that clients may initiate transmissions.

This page varies depending on the WAN interface of your Motorola Netopia® Gateway.WAN IP Interfaces: Your IP interfaces are listed.PPP over Ethernet interfaceClick the PPP over Ethernet link to conﬁgure it.The WAN IP Interface page appears.Enable Interface: You can disable the interface by unchecking the checkbox. However, doing so will dis-able all ability for your LAN users to connect to the WAN using the Gateway.Address Mapping (NAT): Speciﬁes whether you want the Gateway to use network address translation (NAT) when communicating with remote routers. NAT lets you conceal details of your network from remote routers. By default, address mapping is enabled.

Administrator’s Handbook68Restrictions: This setting determines the types of trafﬁc the Gateway accepts from the WAN. Admin Dis-abled means that Gateway trafﬁc is accepted but administrative commands are ignored. None means that all trafﬁc is accepted. When PPP is enabled, Admin Disabled is the default.DHCP/PPPoE/PPPoA Autosensing: The pull-down menu allows you to select an autosens-ing feature, or to disable it. Selecting between PPPoE/DHCP or PPPoE/PPPoA enables automatic sensing of your WAN connection type. If you select PPPoE/DHCP, the gateway attempts to connect using PPPoE ﬁrst. If the Gateway fails to connect after 60 seconds, it switches to DHCP. As soon as it can connect via DHCP, the Gateway chooses and sets DHCP as its default. Otherwise, after attempting to connect via DHCP for 60 seconds, the Gateway switches back to PPPoE. The Gateway will continue to switch back and forth in this manner until it successfully connects. Similarly, selecting PPPoE/PPPoA causes the Gateway to attempt to con-nect by trying these protocols in parallel, and using the ﬁrst one that is successful. If you choose to disable the feature, select Off.ISP Username: This is the username used to authenticate your Gateway with the Service Provider's net-work. This value is given to you by your Service Provider.ISP Password: This is the password used to authenticate your Gateway with the Service Provider's net-work. This value is given to you by your Service Provider.Connection Type: The pull-down menu allows you to choose to have either an uninterrupted connection or an as-needed connection.• Always On: This setting provides convenience, but it leaves your network permanently connected to the Internet.• Instant On furnishes almost all the beneﬁts of an Always On connection, but has additional security beneﬁts: - Your network cannot be attacked when it is not connected. - Your network may change address with each connection, making it more difﬁcult to attack.Timeout: (only appears if Instant-On Connection Type is selected) Speciﬁes the time in seconds before dis-connect if there is no trafﬁc over the Internet link.

69Advanced:If you click the Advanced link, the Advanced WAN IP Interface conﬁguration page appears.Local Address: If this value is 0.0.0.0, the Gateway will acquire its IP address from your ISP. Otherwise this address is assigned to the virtual PPP interface.Peer Address: Address of the server on the Service Provider side of the ppp link. This peer will attempt to negotiate the local IP address if IP Address = 0.0.0.0. If the remote peer does not accept the IP address, the link will not come up.RIP Receive Mode: Routing Information Protocol (RIP) is needed if there are IP routers on other seg-ments of your Ethernet network that the Motorola Netopia® Gateway needs to recognize. Set to Off, Netopia Embedded Software Version 7.7.4 will not accept information from either RIP-1 nor RIP-2 rout-ers. With Receive RIP Mode set to RIP-1, the Motor-ola Netopia® Gateway will accept routing information provided by RIP packets from other routers that use the same subnet mask. Set to RIP-2, Netopia Embedded Software Version 7.7.4 will accept routing information provided by RIP packets from other rout-ers that use different subnet masks.From the pull-down menu, choose Off, RIP-1, RIP-2, RIP-1 compatibility, or RIP-2 with MD5.RIP Receive MD5 Key: (Only appears if RIP-2 with MD5 RIP Receive Mode is selected) The purpose of MD5 authentication is to provide an additional level of conﬁdence that a RIP packet received was generated by a reliable source. In other words, MD5 authentica-tion provides an enhanced level of security that information that your PC receives does not originate from a malicious source posing as part of your network. This ﬁeld allows you to enter an MD5 encryption key of from 1 – 16 ASCII characters for authenticating RIP receipts.Multicast Forward: If you check this checkbox, this interface acts as an IGMP proxy host, and IGMP pack-ets are transmitted and received on this interface on behalf of IGMP hosts on the LAN interface.IGMP Null Source Address: If you check this checkbox, the source IP address of every IGMP packet trans-mitted from this interface is set to 0.0.0.0. This complies with the requirements of TR-101, and removes the need for a publicly advertised IP address on the WAN interface. This checkbox is only available if “Mul-ticast Forward” is checked.

Administrator’s Handbook74Your Motorola Netopia® ADSL Gateway supports VPI/VCI autodetection by default. If VPI/VCI autodetec-tion is enabled, the ATM Circuits page displays VPI/VCI = 0. If you conﬁgure a new ATM VPI/VCI pair, upon saving and restarting, autodetection is disabled and only the new VPI/VCI pair conﬁguration will be enabled.VPI/VCI Autodetection consists of eight static VPI/VCI pair conﬁgurations. These are 0/35, 8/35, 0/32, 8/32, 1/35, 1/1, 1/32, 2/32. These eight VPI/VCI pairs will be created if the Gateway is conﬁgured for autodetection. the Gateway does not establish a circuit using any of these preconﬁgured VPI/VCI pairs, then you can manually enter a VPI/VCI pair in the ATM Circuits page.PPPoE with IPoE: For ADSL Gateways, you must conﬁgure two VCCs with the same VPI/VCI settings to provide concurrent PPPoE with IPoE support.You must use ﬁxed VPI/VCI values for PPPoE with IPoE. You cannot have both VPI/VCI values set to 0/0; autodetection does not work in this mode.

75Once the VCCs have been conﬁgured, the WAN IP Interfaces screen displays the additional interface which you can then conﬁgure as required.

Administrator’s Handbook76ATM Trafﬁc Shaping: You can prioritize delay-sensitive data by conﬁguring the Quality of Service (QoS) characteristics of the virtual circuit. Click the ATM Trafﬁc Shaping link.You can choose UBR (Unspeciﬁed Bit Rate), CBR (Constant Bit Rate), or VBR (Variable Bit Rate) from the pull-down menu and set the Peak Cell Rate (PCR) in the editable ﬁeld.UBR (Unspeciﬁed Bit Rate) guarantees no minimum transmission rate. Cells are transmitted on a “best effort” basis. However, there is a cap on the maximum transmission rate for UBR VCs. In a practi-cal situation:• UBR VCs should be transmitted at a priority lower than CBR.• Bandwidth should be shared equally among UBR VCs.UBR applications are non-real-time trafﬁc such as IP data trafﬁc.CBR (Constant Bit Rate) guarantees a certain transmission rate (although the application may underutilize this bandwidth). A Peak Cell Rate (PCR) characterizes CBR. CBR is most suited for real time applications such as real time voice / video, although it can be used for other applications.VBR (Variable Bit Rate) This class is characterized by:• a Peak Cell Rate (PCR), which is a temporary burst, not a sustained rate, and • a Sustained Cell Rate (SCR),• a Burst Tolerance (BT), speciﬁed in terms of Maximum Burst Size (MBS). The MBS is the maximum number of cells that can be transmitted at the peak cell rate and should be less than, or equal to the Peak Cell Rate, which should be less than, or equal to the line rate. VBR has two sub-classes:a. VBR non-real-time (VBR-nrt): Typical applications are non-real-time trafﬁc, such as IP data trafﬁc. This class yields a fair amount of Cell Delay Variation (CDV).b. VBR real time (VBR-rt): Typical applications are real-time trafﬁc, such as compressed voice over IP and video conferencing. This class transmits cells with a more tightly bounded Cell Delay Variation. The applications follow CBR.☛ Note:The difference between VBR-rt and VBR-nrt is the tolerated Cell Delay Variation range and the provisioned Maximum Burst Size.

Administrator’s Handbook78Link: AdvancedSelected Advanced options are discussed in the pages that follow. Many are self-explanatory or are dic-tated by your service provider.The following are typical links under Conﬁgure -> Advanced (some models offer other links):

79Link: IP Static RoutesA static route identiﬁes a manually conﬁgured pathway to a remote network. Unlike dynamic routes, which are acquired and conﬁrmed periodically from other routers, static routes do not time out. Consequently, static routes are useful when working with PPP, since an intermittent PPP link may make maintenance of dynamic routes problematic.When you click the Static Routes link, the IP Static Routes page appears.You can conﬁgure as many as 32 static IP routes for the Gateway. To add a static route, click the Add but-ton.The IP Static Route Entry page appears.•Destination Network: Enter the IP address of the static route. It may not be 0.0.0.0.•Netmask: Enter the subnet mask for the IP network at the other end of the static route. The subnet mask associated with the destination network must represent the same network class (A, B, or C) or a lower class (such as a class C subnet mask or class B network number) to be valid.•Interface Type: Choose PPP (vcc1) – depending on the interface; typically vcc1 for DSL – or IP Address from the pull-down menu to specify whether the static route is accessible through PPP or IP address.•Gateway: Enter the IP address of the gateway for the static route. The default gateway must be located on a network connected to your Motorola Netopia® Gateway conﬁgured interface.•Metric: Speciﬁes the hop count for the static route. Enter a number from 1 to 15 to indicate the number of routes (actual or best guess) a packet must traverse to reach the remote network. Some metric or a value of 1 will be used to indicate:• The remote network is one router away and the static route is the best way to reach it.• The remote network is more than one router away but the static route should not be replaced by a dynamic route, even if the dynamic route is more efﬁcient.

Administrator’s Handbook80•RIP Advertise: From the pull-down menu, choose how the static route should be advertised via RIP:• Split Horizon: Do not advertise route if the gateway is on the same subnet.• Always: Advertise route in all RIP messages.• Never: Do not advertise route.Click the Submit button. The Alert icon will appear, so that you can switch to the Save Changes page, when you are ﬁnished.Once you save your changes, you will be returned to the IP Static Routes entry screen.•You can continue to Add, Edit, or Delete Static Routes from this screen.When you are ﬁnished, click the Alert icon , switch to the Save Changes page, and click the Save Changes link.

81Link: IP Static ARPYour Gateway maintains a dynamic Address Resolution Protocol (ARP) table to map IP addresses to Ether-net (MAC) addresses. It populates this ARP table dynamically, by retrieving IP address/MAC address pairs only when it needs them. Optionally, you can deﬁne static ARP entries to map IP addresses to their corre-sponding Ethernet MAC addresses. Unlike dynamic ARP table entries, static ARP table entries do not time out. The IP address cannot be 0.0.0.0. The Ethernet MAC address entry is in nn-nn-nn-nn-nn-nn (hexadeci-mal) format.

Administrator’s Handbook82Link: PinholesPinholes allow you to transparently route selected types of network trafﬁc, such as FTP requests or HTTP (Web) connections, to a speciﬁc host behind the Gateway. Creating a pinhole allows access trafﬁc originat-ing from a remote connection (WAN) to be sent to the internal computer (LAN) that is speciﬁed in the Pin-hole page.Pinholes are common for applications like multiplayer online games. Refer to software manufacturer appli-cation documentation for speciﬁc trafﬁc types and port numbers.Conﬁgure Speciﬁc Pinholes. Planning for Your Pinholes. Determine if any of the service applications that you want to provide on your LAN stations use TCP or UDP protocols. If an application does, then you must conﬁgure a pinhole to implement port forwarding. This is accessed from the Advanced -> Pinholes page. Example: A LAN Requiring Three Pinholes . The procedure on the following pages describes how you set up your NAT-enabled Motorola Netopia® Gateway to support three separate applications. This requires passing three kinds of speciﬁc IP trafﬁc through to your LAN. Application 1: You have a Web server located on your LAN behind your Motorola Netopia® Gateway and would like users on the Internet to have access to it. With NAT “On”, the only externally visible IP address on your network is the Gateway’s WAN IP (supplied by your Service Provider). All trafﬁc intended for that LAN Web server must be directed to that IP address.Application 2: You want one of your LAN stations to act as the “central repository” for all email for all of the LAN users.Application 3: One of your LAN stations is specially conﬁgured for game applications. You want this spe-ciﬁc LAN station to be dedicated to games. A sample table to plan the desired pinholes is:For this example, Internet protocols TCP and UDP must be passed through the NAT security feature and the Gateway’s embedded Web (HTTP) port must be re-assigned by conﬁguring new settings on the Internal Servers page.WAN Trafﬁc Type Protocol Pinhole Name LAN Internal IP Address Web TCP my-webserver 192.168.1.1 Email TCP my-mailserver 192.168.1.2 Games UDP my-games 192.168.1.3

83☛ TIPS for making Pinhole Entries:1. If the port forwarding feature is required for Web services, ensure that the embedded Web server’s port number is re-assigned PRIOR to any Pinhole data entry. 2. Enter data for one Pinhole at a time.3. Use a unique name for each Pinhole. If you choose a duplicate name, it will overwrite the previous information without warning. A diagram of this LAN example is:You can also use the LAN-side address of the Gateway, 192.168.1.x:8100 to access the web and 192.168.1.x:23 to access the telnet server.WANLANEthernet Interface192.168.1.1192.168.1.2192.168.1.3my-webservermy-mailservermy-gamesGatewayNATNAT PinholesEmbeddedWeb Server210.219.41.20210.219.41.20:8100Ethernet InterfaceInternet

Administrator’s Handbook84Pinhole Conﬁguration Procedure. Use the following steps:1. From the Conﬁgure toolbar button -> Advanced link, select the Internal Servers link.Since Port Forwarding is required for this example, the Motorola Netopia® embedded Web server is con-ﬁgured ﬁrst.☛ NOTE:The two text boxes, Web (HTTP) Server Port and Telnet Server Port, on this page refer to the port numbers of the Motorola Netopia® Gateway’s embedded administration ports. To pass Web trafﬁc through to your LAN station(s), select a Web (HTTP) Port number that is greater than 1024. In this example, you choose 8100.2. Type 8100 in the Web (HTTP) Server Port text box. 3. Click the Submit button.4. Click Advanced. Select the Pinholes link to go to the Pinhole page.5. Click Add. Type your speciﬁc data into the Pinhole Entries table of this page. Click Sub-mit.

856. Click on the Add or Edit more Pinholes link. Click the Add button. Add the next Pinhole. Type the speciﬁc data for the second Pinhole.7. Click on the Add or Edit more Pinholes link. Click the Add button. Add the next Pinhole. Type the speciﬁc data for the third Pinhole.☛ NOTE:Note the following parameters for the “my-games” Pinhole:1. The Protocol ID is UDP.2. The external port is speciﬁed as a range.3. The Internal port is speciﬁed as the lower range entry.

Administrator’s Handbook868. Click on the Add or Edit more Pinholes link. Review your entries to be sure they are cor-rect.9. Click the Alert icon.10. Click the Save and Restart link to complete the entire Pinhole creation task and ensure that the parameters are properly saved.☛ NOTE:REMEMBER: When you have re-assigned the port address for the embedded Web server, you can still access this facility.Use the Gateway’s WAN address plus the new port number.In this example it would be <WAN Gateway address>:<new port number> or, in this case, 210.219.41.20:8100You can also use the LAN-side address of the Gateway, 192.168.1.x:8100 to access the web and 192.168.1.x:23 to access the telnet server.

87Link: IPMapsIPMaps supports one-to-one Network Address Translation (NAT) for IP addresses assigned to servers, hosts, or speciﬁc computers on the LAN side of the Motorola Netopia® Gateway. A single static or dynamic (DHCP) WAN IP address must be assigned to support other devices on the LAN. These devices utilize Motorola Netopia®’s default NAT/PAT capabilities.Conﬁgure the IPMaps FeatureFAQs for the IPMaps FeatureBefore conﬁguring an example of an IPMaps-enabled network, review these frequently asked questions. What are IPMaps and how are they used? The IPMaps feature allows multiple static WAN IP addresses to be assigned to the Motorola Netopia® Gateway. Static WAN IP addresses are used to support speciﬁc services, like a web server, mail server, or DNS server. This is accomplished by mapping a separate static WAN IP address to a speciﬁc internal LAN IP address. All trafﬁc arriving at the Gateway intended for the static IP address is transferred to the internal device. All outbound trafﬁc from the internal device appears to originate from the static IP address. Locally hosted servers are supported by a public IP address while LAN users behind the NAT-enabled IP address are protected.IPMaps is compatible with the use of NAT, with either a statically assigned IP address or DHCP/PPP served IP address for the NAT table.What types of servers are supported by IPMaps? IPMaps allows a Motorola Netopia® Gate-way to support servers behind the Gateway, for example, web, mail, FTP, or DNS servers. VPN servers are not supported at this time.Can I use IPMaps with my PPPoE or PPPoA connection? Yes. IPMaps can be assigned to the WAN interface provided they are on the same subnet. Service providers will need to ensure proper routing to all IP addresses assigned to your WAN interface.Will IPMaps allow IP addresses from different subnets to be assigned to my Gate-way? IPMap will support statically assigned WAN IP addresses from the same subnet.WAN IP addresses from different subnets are not supported.

89Link: Default ServerThis feature allows you to:•Direct your Gateway to forward all externally initiated IP trafﬁc (TCP and UDP protocols only) to a default host on the LAN. Enable it for certain situations: – Where you cannot anticipate what port number or packet protocol an in-bound application might use. For example, some network games select arbitrary port numbers when a connection is opened. – When you want all unsolicited trafﬁc to go to a speciﬁc LAN host.•Conﬁgure for IP Passthrough.Conﬁgure a Default Server. This feature allows you to direct unsolicited or non-speciﬁc trafﬁc to a designated LAN station. With NAT “On” in the Gateway, these packets normally would be discarded. For instance, this could be application trafﬁc where you don’t know (in advance) the port or protocol that will be used. Some game applications ﬁt this proﬁle.Use the following steps to setup a NAT default server to receive this information:1. Select the Conﬁgure toolbar button, then Advanced, then the Default Server link.2. From the pull-down menu, select Default-Server. The NAT Server IP Address ﬁeld appears. 3. Determine the IP address of the LAN computer you have chosen to receive the unex-pected or unknown trafﬁc.Enter this address in the NAT Server IP Address ﬁeld.4. Click the Submit button. 5. Click the Alert button.6. Click the Save and Restart link to conﬁrm. Typical Network Diagram. A typical network using the NAT Default Server looks like this:

Administrator’s Handbook90You can also use the LAN-side address of the Gateway, 192.168.1.x to access the web and telnet server.NAT Combination Application. Motorola Netopia®’s NAT security feature allows you to conﬁgure a sophisticated LAN layout that uses both the Pinhole and Default Server capabilities. With this topology, you conﬁgure the embedded administration ports as a ﬁrst task, followed by the Pin-holes and, ﬁnally, the NAT Default Server.When using both NAT pinholes and NAT Default Server the Gateway works with the following rules (in sequence) to forward trafﬁc from the Internet to the LAN:1. If the packet is a response to an existing connection created by outbound trafﬁc from a LAN PC, forward to that station.2. If not, check for a match with a pinhole conﬁguration and, if one is found, forward the packet according to the pinhole rule.3. If there’s no pinhole, the packet is forwarded to the Default Server.IP-Passthrough. Your Gateway offers an IP passthrough feature. The IP passthrough feature allows a single PC on the LAN to have the Gateway’s public address assigned to it. It also provides PAT (NAPT) via the same public IP address for all other hosts on the private LAN subnet. Using IP passthrough:•The public WAN IP is used to provide IP address translation for private LAN computers.•The public WAN IP is assigned and reused on a LAN computer.WANLANEthernet Interface192.168.1.3192.168.1.2192.168.1.1LAN STN #3LAN STN #2NAT Default ServerGatewayNATNAT DefaultEmbeddedWeb Server210.219.41.20210.219.41.20(Port 80 default)NAT protectedEthernet InterfaceInternetServer

91•DHCP address serving can automatically serve the WAN IP address to a LAN computer.When DHCP is used for addressing the designated passthrough PC, the acquired or conﬁgured WAN address is passed to DHCP, which will dynamically conﬁgure a single-servable-address subnet, and reserve the address for the conﬁgured MAC address. This dynamic subnet conﬁguration is based on the local and remote WAN address and subnet mask. If the WAN interface does not have a suitable subnet mask that is usable, for example when using PPP or PPPoE, the DHCP subnet conﬁguration will default to a class C subnet mask.•If you want to manually assign the WAN address to a LAN PC, do not check the DHCP Enable checkbox.•If you check the DHCP Enable checkbox, the screen expands.The Host Hardware Address ﬁeld displays. Here you enter the MAC address of the designated IP-Passthrough computer.•If this MAC address is not all zeroes, then it will use DHCP to set the LAN host's address to the (conﬁg-ured or acquired) WAN IP address.The MAC address must be six colon-delimited or dash-delimited sets of hex digits ('0' – 'FF').•If you leave the MAC address as zeros then the ﬁrst DHCP client will be assigned the WAN address.Once conﬁgured, the passthrough host's DHCP leases will be shortened to two minutes. This allows for timely updates of the host's IP address, which will be a private IP address before the WAN connection is established. After the WAN connection is established and has an address, the passthrough host can renew its DHCP address binding to acquire the WAN IP address.A restriction. Since both the Gateway and the passthrough host will use the same IP address, new ses-sions that conﬂict with existing sessions will be rejected by the Gateway. For example, suppose you are a teleworker using an IPSec tunnel from the Gateway and from the passthrough host. Both tunnels go to the same remote endpoint, such as the VPN access concentrator at your employer’s ofﬁce. In this case, the ﬁrst one to start the IPSec trafﬁc will be allowed; the second one – since, from the WAN, it's indistinguish-able – will fail.

Administrator’s Handbook92Link: Differentiated ServicesWhen you click the Differentiated Services link, the Differentiated Services conﬁguration screen appears.Differentiated Services (Diffserv) allow your Gateway to make Quality of Service (QoS) decisions about what path Internet trafﬁc, such as Voice over IP (VoIP), should travel across your network. For example, you may want streaming video conferencing to use high quality, but more restrictive, connections, or, you might want e-mail to use less restrictive, but less reliable, connections.VDSL and Bonded ADSL models display this screen:Most other models display this screen:•To enable Differentiated Services, check the Enable checkbox.•(Not displayed on VDSL and Bonded ADSL models) Enter a value from 60 to 100 (percent) in the Low-High Priority Ratio ﬁeld. The default is 92.Differentiated Services uses the low-to-high priority queue ratio to regulate trafﬁc ﬂow. For example, to provide the least possible latency and highest possible throughput for high priority trafﬁc, you could set the ratio to 100(%). This would cause the gateway to forward low priority data only after the high priority queue is completely empty. In practice, you should set it to something less than 100%, since the low pri-ority trafﬁc might have to wait too long to be passed, and consequently be subject to time-outs.Click the Submit button.You can then deﬁne Custom Flows. If your applications do not provide Quality of Service (QoS) control, Cus-tom Flows allows you to deﬁne streams for some protocols, port ranges, and between speciﬁc end point addresses.

93•To deﬁne a custom ﬂow, click the Add button.The Custom Flow Entry screen appears.• Name – Enter a name in this ﬁeld to label the ﬂow.• Protocol – Select the protocol from the pull-down menu: TCP (default), UDP, ICMP, or Other. “Other” is appropriate for setting up ﬂows on protocols with non-standard port deﬁnitions. IPSEC and PPTP are common examples.• Numerical Protocol – If you select “Other” protocol, this ﬁeld appears for you to provide its actual protocol number, with a range of 0 – 255.• Direction – Choose Outbound (default), Inbound, or Both from the pull-down menu.• Start Port – For TCP or UDP protocols, you can option-ally specify a range of ports. Enter the starting port here.• End Port – Enter the ending port here.• Inside IP Address/Netmask – For outbound ﬂows, specify an IP address/netmask on your LAN. For inbound ﬂows, this setting is ignored. This setting marks packets from this LAN IP host/network based on the address and netmask information. For outbound ﬂows, the Inside IP Address/Netmask is the source address. If you enter a zero IP address (0.0.0.0), the IP address/netmask ﬁelds will be ignored.• Outside IP Address/Netmask – If you want trafﬁc destined for and originating from a certain WAN IP address to be controlled, enter the IP address and subnet mask here. If you leave the default all-zeroes, the outside address check is ignored. For outbound ﬂows, the outside address is the destination IP address for trafﬁc; for inbound packets, the outside address is the source IP address.Note:When setting the Inside/Outside IP Address/Netmask settings, note that a netmask value can be used to conﬁgure for a network rather than a single IP address.

Administrator’s Handbook94• Quality of Service (QoS) – This is the Quality of Service setting for the ﬂow, based on the TOS bit information. Select Expedite, Assure, or Off (default) from the pull-down menu. The following table out-lines the TOS bit settings and behavior:QoS Setting TOS Bit Value BehaviorOff TOS=000 This custom ﬂow is disabled. You can activate it by selecting one of the two settings below. This setting allows you to pre-deﬁne ﬂows without actually activating them.Assure TOS=001 Use normal queuing and throughput rules, but do not drop pack-ets if possible. Appropriate for applications with no guaranteed delivery mechanism.Expedite TOS=101 Use minimum delay. Appropriate for VoIP and video applications.Network Control TOS=111 Use highest possible priority.

95Link: DNSYour Service Provider may maintain a Domain Name server. If you have the information for the DNS serv-ers, enter it on the DNS page. If your Gateway is conﬁgured to use DHCP to obtain its WAN IP address, the DNS information is automatically obtained from that same DHCP Server.

Administrator’s Handbook96Link: DHCP ServerYour Gateway can provide network conﬁguration information to computers on your LAN, using the Dynamic Host Conﬁguration Protocol (DHCP). If you already have a DHCP server on your LAN, you should turn this service off. If you want the Gateway to provide this service, select Server from the Server Mode pull-down menu, then conﬁgure the range of IP addresses that you would like the Gateway to hand out to your computers.You can also specify the length of time the computers can use the conﬁguration information; DHCP calls this period the lease time.Your Service Provider may, for certain services, want to provide conﬁguration from its DHCP servers to the computers on your LANs. In this case, the Gateway will relay the DHCP requests from your computers to a DHCP server in the Service Provider's network. Select Relay-agent and enter the IP address of the Service Provider's DHCP server in the Server Address ﬁeld. This address is furnished by the Service Provider.☛ NOTE:The relay-agent option only works when NAT is off and the Gateway is in router mode.

97Link: RADIUS ServerRADIUS servers allow external authentication of users by means of a remote authentication database. The remote authentication database is maintained by a Remote Authentication Dial-In User Service (RADIUS) server. In conjunction with Wireless User Authentication, you can use a RADIUS server database to authen-ticate users seeking access to the wireless services, as well as the authorized user list maintained locally within the Gateway.If you click the RADIUS link, the RADIUS Servers screen appears.•RADIUS Server Addr/Name: The default RADIUS server name or IP address that you want to use.•RADIUS Server Secret: The RADIUS secret key used by this server. The shared secret should have the same characteristics as a normal password.•RADIUS Server Port: The port on which the RADIUS server is listening, typically, the default 1812.Click the Submit button.You can also conﬁgure alternate RADIUS servers from the Wireless Conﬁguration pages. See “Use RADIUS Server” on page 65 for more information.

Administrator’s Handbook98Link: SNMPWhen you click the SNMP link, the SNMP conﬁguration page appears.The Simple Network Management Protocol (SNMP) lets a network administrator monitor problems on a net-work by retrieving settings on remote network devices. The network administrator typically runs an SNMP management station program on a local host to obtain information from an SNMP agent. In this case, the Motorola Netopia® Gateway is an SNMP agent. Your Gateway supports SNMP-V1, with the exception of most sets (read-only and traps), and SNMP-V2. (For certain parts of the NPAV2TRAP.MIB – parameters under resNatParams, resDslParams, resSecParams – set is supported.)You enter SNMP conﬁguration information on this page. Your network administrator furnishes the SNMP parameters.☛ WARNING:SNMP presents you with a security issue. The community facility of SNMP behaves somewhat like a password. The community “public” is a well-known community name. It could be used to examine the conﬁguration of your Gateway by your service provider or an uninvited reviewer. The information can be read from the Gateway. If you are strongly concerned about security, you may leave the “public” community blank.

99The Notiﬁcation Type pull-down menu allows you to conﬁgure the type of SNMP notiﬁcations that will be generated: •v1 Trap – This selection will generate notiﬁcations containing an SNMPv1 Trap Protocol Data Unit (PDU)•v2 Trap – This selection will generate notiﬁcations containing an SNMPv2 Trap PDU•Inform – This selection will generate notiﬁcations containing an SNMPv2 InformRequest PDU.To send SNMP traps, you must add IP addresses for each trap receiver you want to have. Click the Add button.The IP Trap Entry screen appears.Enter an IP Trap Entry IP address. This is the destination for SNMP trap messages, the IP address of the host acting as an SNMP console.Click the Submit button. Click the Alert icon, and in the resulting page, click the Save and Restart link.

101The IGMP page appears.You can set the following options:•IGMP Snooping – checking this checkbox enables the Motorola Netopia® Gateway to “listen in” to IGMP trafﬁc. The Gateway discovers multicast group membership for the purpose of restricting multicast transmissions to only those ports which have requested them. This helps to reduce overall network trafﬁc from streaming media and other bandwidth-intensive IP multicast applications.•Robustness – a way of indicating how sensitive to lost packets the network is. IGMP can recover from robustness minus 1 lost IGMP packet. The default value is 2.•Query Interval– the amount of time in seconds between IGMP General Query messages sent by the querier gate-way. The default query interval is 125 seconds. •Query Response Interval – the maximum amount of time in tenths of a second that the IGMP router waits to receive a response to a General Query message. The default query response interval is 10 seconds and must be less than the query interval.•Unsolicited Report Interval – the amount of time in seconds between repetitions of a particular computer’s initial report of membership in a group. The default unsolicited report interval is 10 seconds.•Querier Version – Select a version of the IGMP Querier from the pull-down menu: v1, v2, or v3. The default v3 allows for backward compatibility mode with the earlier versions, and should not need to be changed. However, for administrative purposes you may select either v1 or v2.•Last Member Query Interval – the amount of time in tenths of a second that the IGMP gateway waits to receive a response to a Group-Speciﬁc Query message. The last member query interval is also the amount of time in seconds between successive Group-Speciﬁc Query messages. The default last mem-ber query interval is 1 second (10 deci-seconds).•Last Member Query Count – the number of Group-Speciﬁc Query messages sent before the gateway assumes that there are no members of the host group being queried on this interface. The default last member query count is 2.•Fast Leave – Checking this checkbox enables a non-standard expedited leave mechanism. The querier keeps track of which client is requesting which channel by IP address. When a leave message is received, the querier can check its internal table to see if there are any more clients on this group. If there are none, it immediately sends an IGMP leave message to the upstream querier. By default, Fast Leave is set to Off.•Log Enable – If you check this checkbox, all IGMP messages on both the LAN and the WAN will be logged.•Wireless Multicast to Unicast conversion – This checkbox only appears if IGMP Snooping is enabled. If you check this checkbox, the Gateway replaces the multicast MAC-address with the physical MAC-address of the wireless client. If there is more than one wireless client interested in the same mul-ticast group, the router will revert to multicasting the stream immediately. When one or more wireless clients leave a group, and the router determines that only a single wireless client is interested in the stream, it will once again unicast the stream.Click the Submit button. Click the Alert icon, and in the resulting page, click the Save and Restart link.

103Link: LAN ManagementTR-064 is a LAN-side DSL Gateway conﬁguration speciﬁcation. It is an extension of UPnP. It deﬁnes more services to locally manage the Motorola Netopia® Gateway. While UPnP allows open access to conﬁgure the Gateway's features, TR-064 requires a password to execute any command that changes the Gateway's conﬁguration.TR-064 is enabled by default. To disable it:•Uncheck the Enabled checkbox, and click the Submit button.•The Alert icon will appear in the upper right corner of the web page. Click the Alert icon, and when prompted, click the Save and Restart link.

Administrator’s Handbook104Link: Ethernet BridgeThe Motorola Netopia® Gateway can be used as a bridge, rather than a router. A bridge is a device that joins two networks. As an Internet access device, a bridge connects the home computer directly to the ser-vice provider’s network equipment with no intervening routing functionality, such as Network Address Trans-lation. Your home computer becomes just another address on the service provider’s network. In a DSL connection, the bridge serves simply to convey the digital data information back and forth over your tele-phone lines in a form that keeps it separate from your voice telephone signals.If your service provider’s network is set up to provide your Internet connectivity via bridge mode, you can set your Motorola Netopia® Gateway to be compatible.Bridges let you join two networks, so that they appear to be part of the same physical network. As a bridge for protocols other than TCP/IP, your Gateway keeps track of as many as 512 MAC (Media Access Control) addresses, each of which uniquely identiﬁes an individual host on a network. Your Gateway uses this bridg-ing table to identify which hosts are accessible through which of its network interfaces. The bridging table contains the MAC address of each packet it sees, along with the interface over which it received the packet. Over time, the Gateway learns which hosts are available through its WAN port and/or its LAN port.When conﬁgured in Bridge Mode, the Motorola Netopia® will act as a pass-through device and allow the workstations on your LAN to have public addresses directly on the internet. ☛ NOTE:In this mode the Motorola Netopia® is providing NO ﬁrewall protection as is afforded by NAT. Also, only the workstations that have a public address can access the internet. This can be useful if you have multiple static public IPs on the LAN.Bridging per WAN is supported in conjunction with VLANs – individual WANs can be bridged to the LAN only if the WANs are part of a VLAN. (See “VLAN” on page 107 for more information.) The capability to bridge individual VLANs is supported only if the underlying encapsulation is RFC1483-Bridged (ether-llc).

105Conﬁguring for Bridge Mode1. Browse into the Motorola Netopia® Gateway’s web interface.2. Click on the Conﬁgure button in the upper Menu bar.3. Click on the LAN link.The LAN page appears.4. In the box titled LAN IP Interface (Ethernet 100BT): Make note of the Ethernet IP Address and subnet mask.You can use this address to access the router in the future.5. Click on the Advanced link in the left-hand links toolbar.6. Under the heading of Services, click on the Ether-net Bridge link.The Ethernet Bridge page appears.The appearance of this page varies, depending on your Gateway’s interfaces.7. If available:a. Check the Enable Bridging on Port selection. (This may be Always On.)b. Click Submit.8. If you want the Gateway to do both bridging and routing, check the Enable Concurrent Bridging/Routing checkbox.When this mode is enabled, the Gateway will appear to be a router, but also bridge trafﬁc from the LAN if it has a valid LAN-side address.9. Check the Enable System Bridge checkbox.The window shrinks.

Administrator’s Handbook106b. Click Submit.At this point you should be ready to do the ﬁnal save on the conﬁguration changes you have made. The yellow Alert symbol will appear beneath the Help button on the right-hand end of the menu bar.10. Click on the Alert symbol and you will see whether your changes have been validated.11. If you are satisﬁed with the changes you have made, click Save and Restart in the Save Database box to Apply changes and restart Gateway. You have now conﬁgured your Motorola Netopia® Gateway for bridging, and it will bridge all trafﬁc across the WAN. You will need to make conﬁgurations to your machines on your LAN. These settings must be made in accordance with your ISP. If you ever need to get back into the Motorola Netopia® Gateway again for management reasons, you will need to manually conﬁgure your machine to be in the same subnet as the Ethernet inter face of the Motorola Netopia®, since DHCP server is not operational in bridge mode.

107Link: VLANWhen you click the VLAN link the VLANs page appears.OverviewA Virtual Local Area Network (VLAN) is a network of computers or other devices that behave as if they are connected to the same wire even though they may be physically located on different segments of a LAN. You set up VLANs by conﬁguring the Gateway software rather than hardware. This makes VLANs very ﬂexi-ble. VLANs behave like separate and independent networks.Beginning with Version 7.7.4, VLANs are now strictly layer 2 entities. They can be thought of as virtual Ethernet switches, into which can be added: Ethernet ports, router IP interfaces, ATM PVC/VCC interfaces, SSIDs, and any other physical port such as USB, HPNA, or MOCA. This allows great ﬂexibility on how the components of a system are connected to each other.VLANs are part of Motorola’s VGx Virtual Gateway technology which allows individual port-based VLANs to be treated as separate and distinct “channels.” When data is passed to a Motorola Netopia VGx-enabled broadband gateway, speciﬁc policies, routing, and prioritization parameters can be applied to each individ-ual service, delivering that service to the appropriate peripheral device with the required level of quality of service (QoS). In effect, a single Motorola gateway acts as separate virtual gateways for each distinct ser-vice being delivered.Motorola’s VGx technology maps multiple local VLANs to one or more speciﬁc permanent virtual circuits (PVCs) for DSL, or wide area network VLANs for a ﬁber network. VGx provides service segmentation and QoS controls, service management, and supports delivery of triple play applications: voice for IP Telephony, video for IPTV, and data.Your Gateway supports the following:•Port-based VLANs - these can be used when no trunking is required •Global VLANs - these are used when trunking is required on any port member of the VLAN - Supports 802.1q and 802.1p; both are conﬁgurable •Routed VLANs

Administrator’s Handbook108 - WAN-side VLAN with Multiple WAN IPoE interface support and IP interface-to-VLAN binding - LAN-side VLAN with IP interface-to-VLAN binding - Inter-VLAN routing •Bridged VLANs - these VLANs are used to bridge trafﬁc from LAN to WAN •Prioritization per VLAN and per portEthernet Switching/Policy SetupBefore you conﬁgure any VLANs, the unconﬁgured Gateway is set up as a router composed of a LAN switch, a WAN switch, and a router in the middle, with LAN and WAN IP interfaces connected to their respective switches. These bindings between Ethernet switch ports, IP LAN interface, IP WAN interface and WAN phys-ical ports are automatically created.When you conﬁgure any VLANs, the default bindings are no longer valid, and the system requires explicit binding between IP interfaces and layer 2 inter faces. Each VLAN can be thought of as a layer 2 switch, and enabling each port or interface in a VLAN is analogous to plugging it in to the layer 2 switch.Thereafter, in order for devices to communicate on layer 2, they must be associated in the same VLAN. For devices to communicate at layer 3, the devices must be either on the same VLAN, or on VLANs that have an Inter-VLAN routing group enabled in common.When conﬁguring VLANs you must deﬁne how trafﬁc needs to be forwarded:•If trafﬁc needs to be bridged between LAN and WAN you can create a single VLAN that encompasses the WAN port and LAN ports.•If trafﬁc needs to be routed then you must deﬁne four elements:• LAN-side VLANs• WAN-side VLANs• Associate IP Interfaces to VLANs• Inter-VLAN Routing Groups: conﬁguration of routing between VLANs is done by association of a VLAN to a Routing Group. Trafﬁc will be routed between VLANs within a routing group. The LAN IP Ethernet Interface can be bound to multiple LAN VLANs, but forwarding can be limited between an Ethernet LAN port and a WAN VLAN if you properly conﬁgure Inter-VLAN groups.Inter-VLAN groups are also used to block routing between WAN interfaces. If each WAN IP interface is bound to its own VLAN and if you conﬁgure a different Inter-VLAN group for each WAN VLAN then no rout-ing between WAN IP interfaces is possible. •Example: to route between a VCC and all the LAN ports, which effectively is similar to the default conﬁg-uration without any VLANs:Create a VLAN named "VccWan" consisting of vcc1, ip-vcc1, routing-group 1Create a VLAN named "Lan" consisting of eth0.1, eth0.2, eth0.3, eth0.4, ssid1, ssid2, ssid3, ssid4 (etc.), ip-eth-a, routing-group 1

109An example of multiple VLANs, using a Motorola Netopia® Gateway with VGx managed switch technology, is shown below:A VLAN Model Combining Bridging and RoutingTo conﬁgure VLANs check the Enable checkbox.To create a VLAN select a list item from the main VLAN page and click the Edit button.

Administrator’s Handbook110The VLAN Entry page appears.Check the Enable checkbox, and enter a descriptive name for the VLAN.You can create up to 16 VLANs, and you can also restrict any VLAN, and the computers on it, from adminis-tering the Gateway.•VLAN Name – A descriptive name for the VLAN.•Type – LAN or WAN Port(s) can be enabled on the VLAN. You can choose a type designation as follows:By-Port: indicates that the VLAN is port-based. Trafﬁc sent to this port will be treated as belonging to the VLAN, and will not be forwarded to other ports that are not within a common VLAN segment.Global indicates that the ports joining this VLAN are part of a global 802.1q Ethernet VLAN. This VLAN includes ports on this Router and may include ports within other devices throughout the network. The VID in this case may deﬁne the behavior of trafﬁc between all devices on the network having ports that are members of this VLAN segment.

111•VLAN ID – If you select Global as the VLAN Type, the VLAN ID ﬁeld appears for you to enter a VID. This must be a unique identifying number between 1 and 4094. (A VID of zero (0) is permitted on the Ether-net WAN port only.)•Admin Restricted – If you want to prevent administrative access to the Gateway from this VLAN, check the checkbox.•802.1p Priority Bit: If you set this from the pull-down menu to a value greater than 0, all packets of this VLAN with unmarked priority bits (pbits) will be re-marked to this priority.Click the Submit button.The VLAN Port Conﬁguration screen appears.•Port interfaces available for this VLAN are listed in the left hand column. •Displayed port interfaces vary depending on the kinds of physical ports on your Gateway, for example, Ethernet, USB, and/or wireless.Also, if you have multiple wireless SSIDs deﬁned, these may be displayed as well (See Enable Multiple Wireless IDs on page 59)•For Motorola Netopia® VGx technology models, separate Ethernet switch ports are displayed and may be conﬁgured.To enable any of them on this VLAN, check the associated Enable checkbox(es).Typically you will choose a physical port, such as an Ethernet port (example: eth0.1) or a wireless SSID (example: ssid1).•When you enable an interface, the Tag, Priority, and Promote checkboxes and an 802.1p Priority Bit pull-down menu appear for that interface.

Administrator’s Handbook112Tag – Packets transmitted from this port through this VLAN must be tagged with the VLAN VID. Packets received through this port destined for this VLAN must be tagged with the VLAN VID by the source. The Tag option is only available on Global type ports.Priority – Use any 802.1p priority bits in the VLAN header to prioritize packets within the Gateway’s internal queues, according to DiffServ priority mapping rules. See “Differentiated Services” on page 92 for more information.Promote – Write any 802.1p priority bits into the IP-TOS header bit ﬁeld for received IP packets on this port destined for this VLAN. Write any IP-TOS priority bits into the 802.1p priority bit ﬁeld for tagged IP packets transmitted from this port for this VLAN. All mappings between Ethernet 802.1p and IP-TOS are made according to a pre-deﬁned QoS mapping policy. The pre-deﬁned mapping can now be set in the CLI. See “Queue Conﬁguration” on page 271. See also “Differentiated Services” on page 92 for more information.802.1p Priority Bit – If you set this ﬁeld to a value greater than 0, all packets received on this port with unmarked priority bits (pbits) will be re-marked to this priority. If the port 802.1p PBit is greater than 0, the VLAN 802.1p PBit setting is ignored.•Select an IP Interface for this VLAN if it is to be routed; otherwise leave the default. These selections will vary depending on your IP interfaces. For example, if you have set up multiple VCCs, these will appear in the list as ip-vcc1, ip-vcc2, and so forth.

113•When you select an IP interface, the screen expands to allow you to conﬁgure Inter-Vlan-Groups.Inter-VLAN groups allow VLANs in the group to route trafﬁc to the others; ungrouped VLANs cannot route trafﬁc to each other.•Click the Submit button.•When you are ﬁnished, click the Alert icon in the upper right-hand corner of the screen, and in the resulting screen, click the Save link.•If you want to create more VLANs, click the Advanced link (in the left-hand toolbar) and then the VLAN link in the resulting page, and repeat the process.

Administrator’s Handbook116ExampleThe following is a simple example of how you might conﬁgure some VLANs:You want to conﬁgure a 3347NWG-VGx Gateway with two SSIDs (see “Multiple SSIDs” on page 59 for more information) for two VLANs, allowing both access to the Internet. One SSID will be in the same VLAN as the four ports of the Ethernet Switch, so that those two networks can communicate. The second VLAN will be for the other SSID. The second VLAN will also be denied access to the 3347NWG-VGx web interface and tel-net interface. This setup might be useful if you have a doctor’s ofﬁce or a coffee shop, and you want to keep your customers separated from the rest of the network.1. In the VLANs page, check the Enable checkbox, select VLAN #1 in the VLANs list, and click the Edit button.2. Check the Enable checkbox, and in the VLAN Name box, enter the name you would like.For example, call it Network A.Since this VLAN will be for SSID1 and the Ethernet ports, leave Admin Restricted unchecked. This will give this VLAN access to the Gateway.3. Click the Submit button.4. In the Port Conﬁguration for VLAN:1 page, you add the Port Interfaces you want associ-ated with the VLAN.

117In this case, select all the physical Ethernet ports: eth0.1 through eth0.4, and wireless ssid1. Select ip-eth-a, the IP interface for the group. This will be Inter-Vlan-Group #1. Check the Group-1 checkbox. These ports will be able to communicate with each other.5. Click the Submit button.6. In the VLAN page, select VLAN #2 in the VLANs list, and click the Edit button.The VLAN Name must be given another unique name. For example, call it Network B.Since this is for the second SSID that we don’t want to be given access to the Gateway, check the Admin Restricted checkbox.

Administrator’s Handbook1187. Click the Submit button.8. In the Port Conﬁguration for VLAN: 2 page, you add the Port Interfaces you want asso-ciated with the VLAN.Select the ip-eth-a port interface and check the ssid2 port interface. Make this VLAN a member of Inter-Vlan-Group Group-2.9. Click the Submit button.10. Next, create a VLAN to provide the Inter-Vlan-Groups access to the Internet (WAN).For example, call it WAN VLAN.

119Check the vcc1 checkbox, select the ip-vcc1 IP interface, and check the Inter-Vlan-Group Group-1 and Group-2 checkboxes. Members of Groups 1 and 2 will now be able to communicate with the Internet (WAN), but not with each other.11. Once you have ﬁnished with the conﬁguration of the VLANs, click the Alert icon in the upper right hand corner. This will validate that the settings are legal for your network.12. Click the Save and Restart link.This will restart the Motorola Netopia® Gateway and retain the VLAN conﬁguration.

Administrator’s Handbook120Link: VoIP(supported models only)Voice-over-IP (VoIP) refers to the ability to make voice telephone calls over the Internet. This differs from tra-ditional phone calls that use the Public Switched Telephone Network (PSTN). VoIP calls use an Internet pro-tocol, Session Initiation Protocol (SIP), to transmit sound over a network or the Internet in the form of data packets. Certain Motorola Netopia® Gateway models have two separate voice ports for connecting tele-phone handsets. These models support VoIP. If your Gateway is a VoIP model, you can conﬁgure the VoIP features.When you click the VoIP link, the SIP Line Entry page appears.To enable a VoIP line, select one of the lines from the SIP Line Entry menu that corresponds to the port on the Gateway to which your phone is connected.Click the Edit button. In the resulting screen, check the Enable SIP checkbox.The screen expands to display the features that you can enable for that line.

121SIP Line EntryRegistration Interval (in secs)Length of time the VoIP registration will be valid before it will be renewed. Default is 1 hour.Registrar Server Registration Server name or IP address.Registrar Port Registration Server port. Default is 5060.Proxy Server Proxy server name or IP address.

123The Home page for a VoIP-enabled Gateway with both phone lines registered is shown below.

Administrator’s Handbook124Link: SystemThe System Name defaults to your Gateway's factory identiﬁer combined with its serial number. Some cable-oriented Service Providers use the System Name as an important identiﬁcation and support parame-ter.The System Name can be 1 – 255 characters long; it can include embedded spaces and special charac-ters.The Log Message Level alters the severity at which messages are collected in the Gateway's system log. Do not alter this ﬁeld unless instructed by your Support representative.

125Link: Syslog ParametersYou can conﬁgure a UNIX-compatible syslog client to report a number of subsets of the events entered in the Gateway’s WAN Event History. Syslog sends log-messages to a host that you specify.To enable syslog logging, click on the Syslog Parameters link.Check the Syslog checkbox. The screen expands.•Syslog: Enable syslog logging in the system.•Syslog Host Name/IP Address: Enter the name or the IP Address of the host that should receive sys-log messages.•Facility: From the pull-down menu, select the Syslog facility to be used by the router when generating syslog messages. Options are local0 through local7.•Log Violations: If you check this checkbox, the Gateway will generate messages whenever a packet is discarded because it violates the router's security policy.•Log Access Attempts: If you check this checkbox, the Gateway will generate messages whenever a packet attempts to access the router or tries to pass through the router. This option is disabled by default.•Log Accepted Packets: If you check this checkbox, the Gateway will generate messages whenever a packet accesses the router or passes through the router. This option is disabled by default.☛ NOTE:Syslog needs to be enabled to comply with logging requirements mentioned in The Modular Firewall Certiﬁcation Criteria - Baseline Module - version 4.1 (speciﬁed by ICSA Labs).

129Link: Internal ServersYour Gateway ships with an embedded Web server and support for a Telnet session, to allow ease of use for conﬁguration and maintenance. The default ports of 80 for HTTP and 23 for Telnet may be reassigned. This is necessary if a pinhole is created to support applications using port 80 or 23. See “Pinholes” on page 82. for more information on Pinhole conﬁguration.Web (HTTP) Server Port: To reassign the port number used to access the Motorola Netopia® embedded Web server, change this value to a value greater than 1024. When you next access the embedded Motorola Netopia® Web server, append the IP address with <port number>, (e.g. Point your browser to http://210.219.41.20:8080).Telnet Server Port: To reassign the port number used to access your Motorola Netopia® embedded Telnet server, change this value to a value greater than 1024. When you next access the Motorola Netopia® embedded Telnet server, append the IP address with <port number>, (e.g. telnet 210.219.41.20 2323).You can also use the LAN-side address of the Gateway, 192.168.1.x:8100 to access the web server and 192.168.1.x:2323 to access the telnet server. The value of 0 for an internal server port will disable that server. You can disable Telnet or Web, but not both. If you disabled both ports, you would not be able to reconﬁgure the unit without pressing the reset button.

133Link: BackupThe purpose of Backup is to provide a recovery mechanism in the event that the primary connection fails. A failure can be either line loss, for example by central site switch failure or physical cable breakage, or loss of end-to-end connectivity. Detection of one of these failures causes the Gateway to switch from using the primary DSL WAN connection to an alternate gateway on the Ethernet LAN. In the event of a loss of primary connectivity you have the option of switching back to the primary circuit automatically once it has recovered its connection.A typical application would be to have a LAN connection from your Gateway to another Gateway that has, for example, another DSL modem or Gateway connection to the Internet, and designating the second gateway as the backup gateway. Should the primary WAN connection fail, trafﬁc would be automatically redirected through your alternate gateway device to maintain Internet connectivity.When you click the Backup link, the Backup Options page appears.Select either manual or automatic from the pull-down menu.•If you choose manual, you will have to switch manually to your alternate gateway in the event of a connection failure.•For fail-over purposes, choose automatic.Manual optionsIf you choose manual, you can also choose Auto Recovery. If you chose Auto Recovery, enter the number of minutes that the system should wait before it assumes that a connection has been re-established. This allows you to be sure that the primary WAN connection is well re-established before the Gateway switches back to it from the backup mode. Minimum value is one minute.•Check the Enable Backup Gateway checkbox.•From the pull-down menu, select the Interface Type to which you want to direct the backup con-nection. If you have deﬁned multiple VCCs, you can choose a secondary one. Otherwise, to backup to an IP device on the LAN, choose IP Address.The screen expands to allow you to enter an IP address of your Backup Gateway.Click the Submit button; click the Alert icon, and in the resulting page, click the Save and Restart link.

Administrator’s Handbook134Once Backup is conﬁgured, a new ﬁeld appears in the Home Page.If your DSL WAN link fails, you can switch to your Backup Gateway by clicking the Force Backup button.Automatic optionsIf you select automatic as your Backup option, the screen expands to allow you to enter additional informa-tion.•Failure Timeout (minutes 1-10) – Enter the number of minutes you want the system to wait before the backup port becomes enabled in the event of primary line failure. This allows you to be sure the WAN connection is not merely brieﬂy interrupted before the gateway switches to backup mode.•Ping Host 1 and Ping Host 2 – Select address or name from the pull-down menu enter IP address(es) or resolvable DNS name(s) that the Gateway will ping.The Gateway will ping both addresses simulta-neously at ﬁve-second intervals, recording the ping responses from each host. The Gateway will proceed into backup mode only if neither of the conﬁgured remote hosts responds.☛ Note:For best results, enter an IP address and not a host name. If a host name is used it may not be resolvable, and may keep the interface down.•While the Gateway is in backup mode, it will continue to ping both hosts via the primary interface. If either host responds to a ping and the Auto Recovery checkbox is checked, the Gateway will revert to the primary interface.•If you chose Auto Recovery, select Recovery Timeout (minutes1-10). Enter the number of minutes you want the system to wait before attempting to switch back to the WAN connection. This allows you to be sure that the WAN connection is well re-established before the gateway switches back to it from the backup mode.•Check the Enable Backup Gateway checkbox

Administrator’s Handbook142Link: FirewallUse a Motorola Netopia® FirewallBreakWater Basic Firewall. BreakWater delivers an easily selectable set of pre-conﬁgured ﬁrewall protection levels. For simple implementation these settings (comprised of three levels) are readily available through Motorola Netopia®’s embedded web server interface.BreakWater Basic Firewall’s three settings are:•ClearSailingClearSailing, BreakWater's default setting, supports both inbound and outbound trafﬁc. It is the only basic ﬁrewall setting that fully interoperates with all other Motorola Netopia® software features. •SilentRunningUsing this level of ﬁrewall protection allows transmission of outbound trafﬁc on pre-conﬁgured TCP/UDP ports. It disables any attempt for inbound trafﬁc to identify the Gateway. This is the Internet equivalent of having an unlisted number.•LANdLockedThe third option available turns off all inbound and outbound trafﬁc, isolating the LAN and disabling all WAN trafﬁc.☛ NOTE: BreakWater Basic Firewall operates independent of the NAT functionality on the Gateway.Conﬁguring for a BreakWater SettingUse these steps to establish a ﬁrewall setting:1. Ensure that you have enabled the BreakWater basic ﬁrewall with the appropriate fea-ture key. See See “Use Motorola Netopia® Software Feature Keys” on page 187. for reference.NOTE: The ﬁrewall is now keyed on by default on the 2200-Series Gateways. 2. Click the Security toolbar button.3. Click Firewall.

1434. Click on the radio button to select the protection level you want. Click Submit. Changing the BreakWater setting does not require a restart to take effect. This makes it easy to change the setting “on the ﬂy,” as your needs change.TIPS for making your BreakWater Basic Firewall Selection Basic Firewall BackgroundAs a device on the Internet, a Motorola Netopia® Gateway requires an IP address in order to send or receive trafﬁc.The IP trafﬁc sent or received have an associated application port which is dependent on the nature of the connection request. In the IP protocol standard the following session types are common applications:By receiving a response to a scan from a port or series of ports (which is the expected behavior according to the IP standard), hackers can identify an existing device and gain a potential opening for access to an internet-connected device.Application Select this Level Other ConsiderationsTypical Internet usage(browsing, e-mail)SilentRunningMulti-player online gamingClearSailing Set Pinholes; once deﬁned, pinholes will be active whenever ClearSailing is set.Restore SilentRunning when ﬁnished.Going on vacation LANdLocked Protects your connection while your away.Finished online use for the dayLANdLocked This protects you instead of disconnecting your Gateway connection.Chatting online or using instant messagingClearSailing Set Pinholes; once deﬁned, pinholes will be active whenever ClearSailing is set.Restore SilentRunning when ﬁnished.•ICMP •HTTP •FTP•SNMP •telnet •DHCP

Administrator’s Handbook144To protect LAN users and their network from these types of attacks, BreakWater offers three levels of increasing protection. The following tables indicate the state of ports associated with session types, both on the WAN side and the LAN side of the Gateway.This table shows how inbound trafﬁc is treated. Inbound means the trafﬁc is coming from the WAN into the WAN side of the Gateway. This table shows how outbound trafﬁc is treated. Outbound means the trafﬁc is coming from the LAN-side computers into the LAN side of the Gateway.

Administrator’s Handbook146Link: IPSecWhen you click on the IPSec link, the IPSec conﬁguration screen appears.Your Gateway can support two mechanisms for IPSec tunnels:•IPSec PassThrough supports Virtual Private Network (VPN) clients running on LAN-connected comput-ers. Normally, this feature is enabled.You can disable it if your LAN-side VPN client includes its own NAT interoperability option.Uncheck the Enable IPSec Passthrough checkbox.•SafeHarbour VPN IPSec is a keyed feature that you must purchase. (See “Install Key” on page 187.) It enables Gateway-terminated VPN support.

147SafeHarbour IPSec VPNSafeHarbour VPN IPSec Tunnel provides a single, encrypted tunnel to be terminated on the Gateway, mak-ing a secure tunnel available for all LAN- connected users. This implementation offers the following:•Eliminates the need for VPN client software on individual PCs.•Reduces the complexity of tunnel conﬁguration.•Simpliﬁes the ongoing maintenance for secure remote access.If you have purchased the SafeHarbour IPSec feature key, the IPSec conﬁguration screen offers additional options.A typical SafeHarbour conﬁguration is shown below:

This is mainly used as an identiﬁer for the administrator. The Name parameter is an ASCII value and is limited to 31 characters. The tunnel name does not need to match the peer gateway.Peer External IP AddressThe Peer External IP Address is the public, or routable IP address of the remote gateway or VPN server you are establishing the tunnel with.Encryption Protocol Encryption protocol for the tunnel session.Parameter values supported include NONE or ESP.Authentication ProtocolAuthentication Protocol for IP packet header. The three parameter values are None, Encapsulating Security Payload (ESP) and Authentication Header (AH)Key Management The Key Management algorithm manages the exchange of security keys in the IPSec protocol architecture. SafeHarbour supports the standard Inter-net Key Exchange (IKE)Table 3: IPSec Tunnel Details page parametersField DescriptionName The Name parameter refers to the name of the conﬁgured tunnel. This is mainly used as an identiﬁer for the administrator. The Name parameter is an ASCII value and is limited to 31 characters. The tunnel name does not need to match the peer gateway.Peer Internal NetworkThe Peer Internal IP Network is the private, or Local Area Network (LAN) address of the remote gateway or VPN Server you are communicating with. Peer Internal NetmaskThe Peer Internal IP Netmask is the subnet mask of the Peer Internal IP Network.NAT enable Turns NAT on or off for this tunnel.PAT Address If NAT is enabled, this ﬁeld appears. You can specify a Port Address Trans-lation (PAT) address or leave the default all-zeroes (if Xauth is enabled). If you leave the default. the address will be requested from the remote router and dynamically applied to the Gateway.Negotiation MethodThis parameter refers to the method used during the Phase I key exchange, or IKE process. SafeHarbour supports Main or Aggressive Mode. Main mode requires 3 two-way message exchanges while Aggres-sive mode only requires 3 total message exchanges.Local ID type If Aggressive mode is selected as the Negotiation Method, this option appears. Selection options are: IP Address, Subnet, Hostname, ASCIILocal ID Address/ValueIf Aggressive mode is selected as the Negotiation Method, this ﬁeld appears. This is the local (Gateway-side) IP address (or Name Value, if Sub-net or Hostname are selected as the Local ID Type).

Administrator’s Handbook152Local ID Mask If Aggressive mode is selected as the Negotiation Method, and Subnet as the Local ID Type, this ﬁeld appears. This is the local (Gateway-side) sub-net mask.Remote ID Type If Aggressive mode is selected as the Negotiation Method, this option appears. Selection options are: IP Address, Subnet, Hostname, ASCII.Remote ID Address/ValueIf Aggressive mode is selected as the Negotiation Method, this ﬁeld appears. This is the remote (central-ofﬁce-side) IP address (or Name Value, if Subnet or Hostname are selected as the Local ID Type).Remote ID Mask If Aggressive mode is selected as the Negotiation Method, and Subnet as the Remote ID Type, this ﬁeld appears. This is the remote (central-ofﬁce-side) subnet mask.Pre-Shared Key TypeThe Pre-Shared Key Type classiﬁes the Pre-Shared Key. SafeHarbour sup-ports ASCII or HEX typesPre-Shared Key The Pre-Shared Key is a parameter used for authenticating each side. The value can be ASCII or Hex and a maximum of 64 characters. ASCII is case-sensitive.DH Group Difﬁe-Hellman is a public key algorithm used between two systems to determine and deliver secret keys used for encryption. Groups 1, 2 and 5 are supported. PFS Enable Perfect Forward Secrecy (PFS) is used during SA renegotiation. When PFS is selected, a Difﬁe-Hellman key exchange is required. If enabled, the PFS DH group follows the IKE phase 1 DH group.SA Encrypt Type SA Encr yption Type refers to the symmetric encryption type. This encryp-tion algorithm will be used to encrypt each data packet. SA Encryption Type values supported include DES and 3DES.SA Hash Type SA Hash Type refers to the Authentication Hash algorithm used during SA negotiation. Values supported include MD5 and SHA1. N/A will display if NONE is chosen for Auth Protocol. Invalid SPI Recovery Enabling this allows the Gateway to re-establish the tunnel if either the Motorola Netopia® Gateway or the peer gateway is rebooted.Soft MBytes Setting the Soft MBytes parameter forces the renegotiation of the IPSec Security Associations (SAs) at the conﬁgured Soft MByte value. The value can be conﬁgured between 1 and 1,000,000 MB and refers to data trafﬁc passed. If this value is not achieved, the Hard MBytes parameter is enforced. This parameter does not need to match the peer gateway.Soft Seconds Setting the Soft Seconds parameter forces the renegotiation of the IPSec Security Associations (SAs) at the conﬁgured Soft Seconds value. The value can be conﬁgured between 60 and 1,000,000 seconds. This param-eter does not need to match the peer gateway.Hard MBytes Setting the Hard MBytes parameter forces the renegotiation of the IPSec Security Associations (SAs) at the conﬁgured Hard MByte value. The value can be conﬁgured between 1 and 1,000,000 MB and refers to data trafﬁc passed. This parameter does not need to match the peer gate-way.Hard Seconds Setting the Hard Seconds parameter forces the renegotiation of the IPSec Security Associations (SAs) at the conﬁgured Hard Seconds value. The value can be conﬁgured between 60 and 1,000,000 seconds This parame-ter does not need to match the peer gateway.Table 3: IPSec Tunnel Details page parameters

153IPSec MTU Some ISPs require a setting of e.g. 1492 (or other value). The default 1500 is the most common and you usually don’t need to change this unless otherwise instructed. Accepted values are from 100 – 1500.This is the starting value that is used for the MTU when the IPSec tunnel is installed. It speciﬁes the maximum IP packet length for the encapsulated AH or ESP packets sent by the router. The MTU used on the IPSec connec-tion will be automatically adjusted based on the MTU value in any received ICMP can't fragment error messages that correspond to IPSec trafﬁc initi-ated from the router. Normally the MTU only requires manual conﬁguration if the ICMP error messages are blocked or otherwise not received by the router.Xauth Enable Extended Authentication (XAuth), an extension to the Internet Key Exchange (IKE) protocol. The Xauth extension provides dual authentication for a remote user’s Motorola Netopia® Gateway to establish a VPN, autho-rizing network access to the user’s central ofﬁce. IKE establishes the tun-nel, and Xauth authenticates the speciﬁc remote user's Gateway. Since NAT is supported over the tunnel, the remote user network can have multi-ple PCs behind the client Gateway accessing the VPN. By using XAuth, net-work VPN managers can centrally control remote user authentication.Xauth Username/PasswordXauth authentication credentials.Table 3: IPSec Tunnel Details page parameters

Administrator’s Handbook154Link: Stateful InspectionAll computer operating systems are vulnerable to attack from outside sources, typically at the operating system or Internet Protocol (IP) layers. Stateful Inspection ﬁrewalls intercept and analyze incoming data packets to determine whether they should be admitted to your private LAN, based on multiple criteria, or blocked. Stateful inspection improves security by tracking data packets over a period of time, examining incoming and outgoing packets. Outgoing packets that request speciﬁc types of incoming packets are tracked; only those incoming packets constituting a proper response are allowed through the ﬁrewall.Stateful inspection is a security feature that prevents unsolicited inbound access when NAT is disabled. You can conﬁgure UDP and TCP “no-activity” periods that will also apply to NAT time-outs if stateful inspection is enabled on the interface. Stateful Inspection parameters are active on a WAN interface only if enabled on your Gateway. Stateful inspection can be enabled on a WAN interface whether NAT is enabled or not.Stateful Inspection Firewall installation procedure☛ NOTE:Installing Stateful Inspection Firewall is mandatory to comply with Required Services Security Policy - Residential Category module - Version 4.1 (speciﬁed by ICSA Labs)For more information please go to the following URL: http://www.icsalabs.com/icsa/docs/html/communities/ﬁrewalls/pdf/4.1/baseline.pdf1. Access the router through the web interface from the private LAN.DHCP server is enabled on the LAN by default.2. The Gateway’s Stateful Inspection feature must be enabled in order to prevent TCP, UDP and ICMP packets destined for the router or the private hosts.This can be done by navigating to Expert Mode -> Security -> Stateful Inspection.•UDP no-activity time-out: The time in seconds after which a UDP session will be terminated, if there is no trafﬁc on the session.•TCP no-activity time-out: The time in seconds after which an TCP session will be terminated, if there is no trafﬁc on the session.

155•DoS Detect: If you check this checkbox, the Gateway will monitor packets for Denial of Service attacks.•Exposed Addresses: The hosts speciﬁed in Exposed Addresses will be allowed to receive inbound traf-ﬁc even if there is no corresponding outbound trafﬁc. This is active only if NAT is disabled on a WAN interface.•Stateful Inspection Options: Enable and conﬁgure stateful inspection on a WAN interface.Exposed AddressesYou can specify the IP addresses you want to expose by clicking the Exposed addresses link.Add, Edit, or delete exposed addresses options are active only if NAT is disabled on a WAN interface. The hosts speciﬁed in exposed addresses will be allowed to receive inbound trafﬁc even if there is no corre-sponding outbound trafﬁc.•Start Address: Start IP Address of the exposed host range.•End Address: End IP Address of the exposed host range•Protocol: Select the Protocol of the trafﬁc to be allowed to the host range from the pull-down menu.

It is important to note that a packet ﬁlter does not look into the IP data stream (the User Data from above) to make ﬁltering deci-sions.Basic protocol typesTCP: Transmission Control Protocol. TCP provides reliable packet delivery and has a retransmission mech-anism (so packets are not lost). RFC 793 is the speciﬁcation for TCP.Source IP Address 163.176.132.18Destination IP Address 163.176.4.27Source Port 2541Destination Port 80Protocol TCPDATA User Data

159UDP: User Datagram Protocol. Unlike TCP, UDP does not guarantee reliable, sequenced packet delivery. If data does not reach its destination, UDP does not retransmit the data. RFC 768 is the speciﬁcation for UDP.There are many more ports deﬁned in the Assigned Addresses RFC. The table that follows shows some of these port assignments.Example TCP/UDP PortsFirewall design rulesThere are two basic rules to ﬁrewall design:•“What is not explicitly allowed is denied.”and•“What is not explicitly denied is allowed.”The ﬁrst rule is far more secure, and is the best approach to ﬁrewall design. It is far easier (and more secure) to allow in or out only certain services and deny anything else. If the other rule is used, you would have to ﬁgure out everything that you want to disallow, now and in the future. Firewall LogicFirewall design is a test of logic, and ﬁlter rule ordering is critical. If a packet is forwarded through a series of ﬁlter rules and then the packet matches a rule, the appropriate action is taken. The packet will not for-ward through the remainder of the ﬁlter rules.For example, if you had the following ﬁlter set...Allow WWW access;Allow FTP access;Allow SMTP access;Deny all other packets.and a packet goes through these rules destined for FTP, the packet would forward through the ﬁrst rule (WWW), go through the second rule (FTP), and match this rule; the packet is allowed through.If you had this ﬁlter set for example....Allow WWW access;TCP Port Service UDP Port Service20/21 FTP 161 SNMP23 Telnet 69 TFTP25 SMTP80 WWW144 News

Administrator’s Handbook160Allow FTP access;Deny FTP access;Deny all other packets.and a packet goes through these rules destined for FTP, the packet would forward through the ﬁrst ﬁlter rule (WWW), match the second rule (FTP), and the packet is allowed through. Even though the next rule is to deny all FTP trafﬁc, the FTP packet will never make it to this rule.Implied rulesWith a given set of ﬁlter rules, there is an Implied rule that may or may not be shown to the user. The implied rule tells the ﬁlter set what to do with a packet that does not match any of the ﬁlter rules. An exam-ple of implied rules is as follows:Example ﬁlter set pageThis is an example of the Motorola Netopia® ﬁlter set page:Implied MeaningY+Y+Y=N If all ﬁlter rules are YES, the implied rule is NO.N+N+N=Y If all ﬁlter rules are NO, the implied rule is YES.Y+N+Y=N If a mix of YES and NO ﬁlters, the implied rule is NO.

161Filter basicsIn the source or destination IP address ﬁelds, the IP address that is entered must be the network address of the subnet. A host address can be entered, but the applied subnet mask must be 32 bits (255.255.255.255).Netopia Embedded Software Version 7.7.4 has the ability to compare source and destination TCP or UDP ports. These options are as follows:Example networkExample ﬁltersExample 1 Incoming packet has the source address of 200.1.1.28Item What it meansNo Compare Does not compare TCP or UDP portNot Equal To Matches any port other than what is deﬁnedLess Than Anything less than the port deﬁnedLess Than or Equal Any port less than or equal to the port deﬁnedEqual Matches only the port deﬁnedGreater Than or Equal Matches the port or any port greaterGreater Than Matches anything greater than the port deﬁnedFilter Rule: 200.1.1.0 (Source IP Network Address)255.255.255.128 (Source IP Mask)Forward = No (What happens on match) DataInternetIP 200.1.1.??Input PacketFilter

Administrator’s Handbook162 This incoming IP packet has a source IP address that matches the network address in the Source IP Address ﬁeld in Netopia Embedded Software Version 7.7.4. This will not forward this packet. Example 2 Incoming packet has the source address of 200.1.1.184.This incoming IP packet has a source IP address that does not match the network address in the Source IP Address ﬁeld in Netopia Embedded Software Version 7.7.4. This rule will forward this packet because the packet does not match. Example 3 Incoming packet has the source address of 200.1.1.184.This rule does not match and this packet will be forwarded. Example 4 Incoming packet has the source address of 200.1.1.104.This rule does match and this packet will not be forwarded.

163 Link: Packet Filter When you click the Packet Filter link the Filter Sets screen appears.Security should be a high priority for anyone administering a network connected to the Internet. Using packet ﬁlters to control network communications can greatly improve your network’s security. The Packet Filter engine allows creation of a maximum of eight Filter Sets. Each Filter Set can consist of many rules. There can be a maximum of 32 ﬁlter rules in the system. ☛ WARNING: Before attempting to conﬁgure ﬁlters and ﬁlter sets, please read and understand this entire section thoroughly. Motorola Netopia® Gateways incorporating NAT have advanced security features built in. Improperly adding ﬁlters and ﬁlter sets increases the possibility of loss of communication with the Gateway and the Internet. Never attempt to conﬁgure ﬁlters unless you are local to the Gateway.Although using ﬁlter sets can enhance network security, there are disadvantages:• Filters are complex. Combining them in ﬁlter sets introduces subtle interactions, increasing the likelihood of implementation errors.• Enabling a large number of ﬁlters can have a negative impact on performance. Processing of packets will take longer if they have to go through many checkpoints in addition to NAT.• Too much reliance on packet ﬁlters can cause too little reliance on other security methods. Filter sets are not a substitute for password protection, effective safeguarding of passwords, and general awareness of how your network may be vulnerable.Netopia Embedded Software Version 7.7.4’s packet ﬁlters are designed to provide security for the Internet connections made to and from your network. You can customize the Gateway’s ﬁlter sets for a variety of packet ﬁltering applications. Typically, you use ﬁlters to selectively admit or refuse TCP/IP connections from certain remote networks and speciﬁc hosts. You will also use ﬁlters to screen particular types of connec-tions. This is commonly called ﬁrewalling your network.Before creating ﬁlter sets, you should read the next few sections to learn more about how these powerful security tools work. What’s a ﬁlter and what’s a ﬁlter set? A ﬁlter is a rule that lets you specify what sort of data can ﬂow in and out of your network. A particular ﬁlter can be either an input ﬁlter—one that is used on data (packets) coming in to your network from the Inter-net—or an output ﬁlter—one that is used on data (packets) going out from your network to the Internet.A ﬁlter set is a group of ﬁlters that work together to check incoming or outgoing data. A ﬁlter set can consist of a combination of input and output ﬁlters.

Administrator’s Handbook164 How ﬁlter sets work A ﬁlter set acts like a team of customs inspectors. Each ﬁlter is an inspector through which incoming and outgoing packages must pass. The inspectors work as a team, but each inspects every package individu-ally. Each inspector has a speciﬁc task. One inspector’s task may be to examine the destination address of all outgoing packages. That inspector looks for a certain destination—which could be as speciﬁc as a street address or as broad as an entire country—and checks each package’s destination address to see if it matches that destination. A ﬁlter inspects data packets like a customs inspector scrutinizing packages. Filter priority Continuing the customs inspectors analogy, imagine the inspectors lined up to examine a package. If the package matches the ﬁrst inspector’s criteria, the package is either rejected or passed on to its destination, depending on the ﬁrst inspector’s particular orders. In this case, the package is never seen by the remaining inspectors.If the package does not match the ﬁrst inspector’s criteria, it goes to the second inspector, and so on. You can see that the order of the inspectors in the line is very important.For example, let’s say the ﬁrst inspector’s orders are to send along all pack-ages that come from Rome, and the second inspector’s orders are to reject all packages that come from France. If a package arrives from Rome, the ﬁrst inspector sends it along without allowing the second inspector to see it. A package from Paris is ignored by the ﬁrst inspector, rejected by the second inspector, and never seen by the others. A package from London is ignored by the ﬁrst two inspectors, so it’s seen by the third inspector.In the same way, ﬁlter sets apply their ﬁlters in a particular order. The ﬁrst ﬁl-ter applied can forward or discard a packet before that packet ever reaches any of the other ﬁlters. If the ﬁrst ﬁlter can neither forward nor discard the packet (because it cannot match any criteria), the second ﬁlter has a chance to forward or reject it, and so on. Because of this hierarchical structure, each ﬁlter is said to have a priority. The ﬁrst ﬁlter has the highest priority, and the last ﬁlter has the lowest priority.INSPECTORFROM:TO:FROM:TO:FROM:TO:APPROVEDpacketfirstfiltermatch?yesforwarddiscard?to networkdiscard(delete)forwardnoto nextfiltersendor

165 How individual ﬁlters work As described above, a ﬁlter applies criteria to an IP packet and then takes one of three actions: • Forwards the packet to the local or remote network • Blocks (discards) the packet • Ignores the packetA ﬁlter forwards or blocks a packet only if it ﬁnds a match after applying its criteria. When no match occurs, the ﬁlter ignores the packet. A ﬁltering rule The criteria are based on information contained in the packets. A ﬁlter is simply a rule that prescribes cer-tain actions based on certain conditions. For example, the following rule qualiﬁes as a ﬁlter: “Block all Telnet attempts that originate from the remote host 199.211.211.17.” This rule applies to Telnet packets that come from a host with the IP address 199.211.211.17. If a match occurs, the packet is blocked.Here is what this rule looks like when imple-mented as a ﬁlter in Netopia Embedded Software Version 7.7.4: To understand this particular ﬁlter, look at the parts of a ﬁlter. Parts of a ﬁlter A ﬁlter consists of criteria based on packet attributes. A typical ﬁlter can match a packet on any one of the following attributes: • The source IP address and subnet mask (where the packet was sent from) • The destination IP address and subnet mask (where the packet is going) • The TOS bit setting of the packet. Certain types of IP packets, such as voice or multime-dia packets, are sensitive to delays introduced by the network. A delay-sensitive packet is identiﬁed by a special low-latency setting called the TOS bit. It is important for such packets to be received rapidly or the quality of service degrades. • The type of higher-layer Internet protocol the packet is carrying, such as TCP or UDP Port numbers A ﬁlter can also match a packet’s port number attributes, but only if the ﬁlter’s protocol type is set to TCP or UDP, since only those protocols use port numbers. The ﬁlter can be conﬁgured to match the following: • The source port number (the port on the sending host that originated the packet) • The destination port number (the port on the receiving host that the packet is destined for)

Administrator’s Handbook166 By matching on a port number, a ﬁlter can be applied to selected TCP or UDP services, such as Telnet, FTP, and World Wide Web. The following tables show a few common services and their associated port numbers: Port number comparisons A ﬁlter can also use a comparison option to evaluate a packet’s source or destination port number. The comparison options are: • No Compare: No comparison of the port number speciﬁed in the ﬁlter with the packet’s port number. • Not Equal To: For the ﬁlter to match, the packet’s port number cannot equal the port number speciﬁed in the ﬁlter. • Less Than: For the ﬁlter to match, the packet’s port number must be less than the port number speci-ﬁed in the ﬁlter. • Less Than or Equal: For the ﬁlter to match, the packet’s port number must be less than or equal to the port number speciﬁed in the ﬁlter. • Equal: For the ﬁlter to match, the packet’s port number must equal the port number speciﬁed in the ﬁl-ter. • Greater Than: For the ﬁlter to match, the packet’s port number must be greater than the port number speciﬁed in the ﬁlter. • Greater Than or Equal: For the ﬁlter to match, the packet’s port number must be greater than or equal to the port number speciﬁed in the ﬁlter.Other ﬁlter attributesThere are three other attributes to each ﬁlter:•The ﬁlter’s order (i.e., priority) in the ﬁlter set•Whether the ﬁlter is currently active•Whether the ﬁlter is set to forward packets or to block (discard) packetsInternet service TCP port Internet service TCP portFTP 20/21 Finger 79Telnet 23 World Wide Web 80SMTP (mail) 25 News 144Gopher 70 rlogin 513Internet service UDP port Internet service UDP portWho Is 43 TFTP 69World Wide Web 80 who 513SNMP 161

167Putting the parts togetherWhen you display a ﬁlter set, its ﬁlters are displayed as rows in a table:The table’s columns correspond to each ﬁlter’s attributes:•#: The ﬁlter’s priority in the set. Filter number 1, with the highest priority, is ﬁrst in the table.•Fwd: Shows whether the ﬁlter forwards (Yes) a packet or discards (No) it when there’s a match. •Src-IP: The packet source IP address to match.•Src-Mask: The packet source subnet mask to match.•Dst-IP: The packet destination IP address to match.•Dst-Mask: The packet destination IP address to match.•Protocol: The protocol to match. This can be entered as a number (see the table below) or as TCP or UDP if those protocols are used.•Src Port: The source port to match. This is the port on the sending host that originated the packet.•Dst Port: The destination port to match. This is the port on the receiving host for which the packet is intended.•NC: Indicates No Compare, where speciﬁed.Filtering example #1Returning to our ﬁltering rule example from above (see page 165), look at how a rule is translated into a ﬁl-ter. Start with the rule, then ﬁll in the ﬁlter’s attributes:•The rule you want to implement as a ﬁlter is:“Block all Telnet attempts that originate from the remote host 199.211.211.17.”Protocol Number to use Full nameN/A 0 Ignores protocol typeICMP 1 Internet Control Message ProtocolTCP 6 Transmission Control ProtocolUDP 17 User Datagram Protocol

Administrator’s Handbook168•The host 199.211.211.17 is the source of the Telnet packets you want to block, while the destination address is any IP address. How these IP addresses are masked determines what the ﬁnal match will be, although the mask is not displayed in the table that displays the ﬁlter sets (you set it when you create the ﬁlter). In fact, since the mask for the destination IP address is 0.0.0.0, the address for Destination IP address could have been anything. The mask for Source IP address must be 255.255.255.255 since an exact match is desired.• Source IP Address = 199.211.211.17• Source IP address mask = 255.255.255.255• Destination IP Address = 0.0.0.0• Destination IP address mask = 0.0.0.0•Using the tables on page 166, ﬁnd the destination port and protocol numbers (the local Telnet port):• Protocol = TCP (or 6)• Destination Port = 23•The ﬁlter should be enabled and instructed to block the Telnet packets containing the source address shown in step 2:• Forward = uncheckedThis four-step process is how we produced the following ﬁlter from the original rule:

169Filtering example #2Suppose a ﬁlter is conﬁgured to block all incoming IP packets with the source IP address of 200.233.14.0, regardless of the type of connection or its destination. The ﬁlter would look like this:This ﬁlter blocks any packets coming from a remote network with the IP network address 200.233.14.0. The 0 at the end of the address signiﬁes any host on the class C IP network 200.233.14.0. If, for example, the ﬁlter is applied to a packet with the source IP address 200.233.14.5, it will block it.In this case, the mask, must be set to 255.255.255.0. This way, all packets with a source address of 200.233.14.x will be matched correctly, no matter what the ﬁnal address byte is.☛ Note:The protocol attribute for this ﬁlter is Any by default. This tells the ﬁlter to ignore the IP protocol or type of IP packet.Design guidelinesCareful thought must go into designing a new ﬁlter set. You should consider the following guidelines: •Be sure the ﬁlter set’s overall purpose is clear from the beginning. A vague purpose can lead to a faulty set, and that can actually make your network less secure.•Be sure each individual ﬁlter’s purpose is clear.•Determine how ﬁlter priority will affect the set’s actions. Test the set (on paper) by determining how the ﬁlters would respond to a number of different hypothetical packets.•Consider the combined effect of the ﬁlters. If every ﬁlter in a set fails to match on a particular packet, the packet is:• Forwarded if all the ﬁlters are conﬁgured to discard (not forward)• Discarded if all the ﬁlters are conﬁgured to forward• Discarded if the set contains a combination of forward and discard ﬁlters

Administrator’s Handbook170An approach to using ﬁltersThe ultimate goal of network security is to prevent unauthorized access to the network without compromis-ing authorized access. Using ﬁlter sets is part of reaching that goal. Each ﬁlter set you design will be based on one of the following approaches:•That which is not expressly prohibited is permitted.•That which is not expressly permitted is prohibited.It is strongly recommended that you take the latter, and safer, approach to all of your ﬁlter set designs.

171Working with IP Filters and Filter SetsTo work with ﬁlters and ﬁlter sets, begin by accessing the ﬁlter set pages.☛ NOTE:Make sure you understand how ﬁlters work before attempting to use them. Read the section “Packet Filter” on page 163.The procedure for creating and maintaining ﬁlter sets is as follows:1. Add a new ﬁlter set.See Adding a ﬁlter set, below.2. Create the ﬁlters for the new ﬁlter set.See “Adding ﬁlters to a ﬁlter set” on page 172.3. Associate the ﬁlter set with either the LAN or WAN interface.See “Associating a Filter Set with an Interface” on page 176.The sections below explain how to execute these steps.Adding a ﬁlter setYou can create up to eight different custom ﬁlter sets. Each ﬁlter set can contain up to 16 output ﬁlters and up to 16 input ﬁlters. There can be a maximum of 32 ﬁlter rules in the system.To add a new ﬁlter set, click the Add button in the Filter Sets page. The Add Filter Set page appears.Enter new name for the ﬁlter set, for example Filter Set 1.To save the ﬁlter set, click the Submit button. The saved ﬁlter set is empty (contains no ﬁlters), but you can return to it later to add ﬁlters (see “Adding ﬁlters to a ﬁlter set”).☛ NOTE:As you begin to build a ﬁlter set, and as you add ﬁlters, after your ﬁrst entry, the Alert icon

Administrator’s Handbook172 will appear in the upper right corner of the web page. It will remain until all of your changes are entered and validated. You need not immediately restart the Gateway until your ﬁl-ter set is complete. See “Associating a Filter Set with an Interface” on page 176.Adding ﬁlters to a ﬁlter setThere are two kinds of ﬁlters you can add to a ﬁlter set: input and output. Input ﬁlters check packets received from the Internet, destined for your network. Output ﬁlters check packets transmitted from your network to the Internet.Packets in Netopia Embedded Software Version 7.7.4 pass through an input ﬁlter if they originate from the WAN and through an output ﬁlter if they’re being sent out to the WAN.The process for adding input and output ﬁlters is exactly the same. The main difference between the two involves their reference to source and destination. From the perspective of an input ﬁlter, your local network is the destination of the packets it checks, and the remote network is their source. From the perspective of an output ﬁlter, your local network is the source of the packets, and the remote network is their destination.To add a ﬁlter, select the Filter Set Name to which you will add a ﬁlter, and click the Edit button. Type of ﬁlter Source means Destination meansInput ﬁlter The remote network The local networkOutput ﬁlter The local network The remote networkThe Motorola Netopia® Routerinput filteroutput filterLANWANpacketpacket

173The Filter Set page appears.☛ Note:There are two Add buttons in this page, one for input ﬁlters and one for output ﬁlters. In this section, you’ll learn how to add an input ﬁlter to a ﬁlter set. Adding an output ﬁlter works exactly the same way, providing you keep the different source and destination perspectives in mind.

Administrator’s Handbook1741. To add a ﬁlter, click the Add button under Input Rules.The Input Rule Entry page appears.2. If you want the ﬁlter to forward packets that match its criteria to the destination IP address, check the Forward checkbox.If Forward is unchecked, packets matching the ﬁlter’s criteria will be discarded.3. Enter the Source IP address this ﬁlter will match on.You can enter a subnet or a host address.4. Enter the Source Mask for the source IP address.This allows you to further modify the way the ﬁlter will match on the source address. Enter 0.0.0.0 to force the ﬁlter to match on all source IP addresses, or enter 255.255.255.255 to match the source IP address exclusively.5. Enter the Destination IP Address this ﬁlter will match on. You can enter a subnet or a host address.6. Enter the Destination Mask for the destination IP address.This allows you to further modify the way the ﬁlter will match on the destination address. Enter 0.0.0.0 to force the ﬁlter to match on all destination IP addresses.7. If desired, you can enter a TOS and TOS Mask value.See “Policy-based Routing using Filtersets” on page 177 for more information.8. Select Protocol from the pull-down menu: ICMP, TCP, UDP, Any, or the number of another IP transport protocol (see the table on page 167).If Protocol Type is set to TCP or UDP, the settings for port comparison will appear. These settings only take effect if the Protocol Type is TCP or UDP.9. From the Source Port Compare pull-down menu, choose a comparison method for the ﬁlter to use on a packet’s source port number.Then select Source Port and enter the actual source port number to match on (see the table on page 166).10. From the Destination Port Compare pull-down menu, choose a comparison method for the ﬁlter to use on a packet’s destination port number.Then select Destination Port and enter the actual destination port number to match on (see the table on page 166).

When you are ﬁnished conﬁguring the ﬁlter, click the Submit button to save the ﬁlter in the ﬁlter set.Viewing ﬁltersTo display the table of input or output ﬁlters, select the Filter Set Name in the Filter Set page and click the Add or Edit button.The table of ﬁlters in the ﬁltersets appears.Modifying ﬁltersTo modify a ﬁlter, select a ﬁlter from the table and click the Edit button. The Rule Entry page appears. The parameters in this page are set in the same way as the ones in the original Rule Entry page (see “Adding ﬁl-ters to a ﬁlter set” on page 172).Deleting ﬁltersTo delete a ﬁlter, select a ﬁlter from the table and click the Delete button. Moving ﬁltersTo reorganize the ﬁlters in a ﬁlter set, select a ﬁlter from the table and click the Move Up or Move Down button to place the ﬁlter in the desired priority position.Deleting a ﬁlter setIf you delete a ﬁlter set, all of the ﬁlters it contains are deleted as well. To reuse any of these ﬁlters in another set, before deleting the current ﬁlter set you’ll have to note their conﬁguration and then recreate them.To delete a ﬁlter set, select the ﬁlter set from the Filter Sets list and click the Delete button.

Administrator’s Handbook176Associating a Filter Set with an InterfaceOnce you have created a ﬁlter set, you must associate it with an interface in order for it to be effective. Depending on its application, you can associate it with either the WAN (usually the Internet) interface or the LAN.To associate an ﬁlter set with the LAN, return to the Filter Sets page.Click the Ethernet 100BT link.The Ethernet 100BT page appears.From the pull-down menu, select the ﬁlter set to associate with this interface.Click the Submit button. The Alert icon will appear in the upper right corner of the page.Click the Alert icon to go to the validation page, where you can save your conﬁguration.You can repeat this process for both the WAN and LAN interfaces, to associate your ﬁlter sets.When you return to the Filter Sets page, it will display your interface associations.

177Policy-based Routing using FiltersetsNetopia Embedded Software Version 7.7.4 offers the ability to route IP packets using criteria other than the destination IP address. This is called policy-based routing.You specify the routing criteria and routing information by using IP ﬁltersets to determine the forwarding action of a particular ﬁlter.You specify a gateway IP address, and each packet matching the ﬁlter is routed according to that gateway address, rather than by means of the global routing table.In addition, the classiﬁer list in a ﬁlter includes the TOS ﬁeld. This allows you to ﬁlter on TOS ﬁeld settings in the IP packet, if you want.To use the policy-based routing feature, you create a ﬁlter that forwards the trafﬁc. •Check the Forward checkbox. This will display the Force Rout-ing options.•Check the Force Route checkbox.•Enter the Gateway IP address in standard dotted-quad nota-tion to which the trafﬁc should be forwarded.•You can enter Source and Destination IP Address(es) and Mask(s), Protocol Type, and Source and Destination Port ID(s) for the ﬁlter, if desired.TOS ﬁeld matchingNetopia Embedded Software Version 7.7.4 includes two parameters for an IP ﬁlter: TOS and TOS Mask. Both ﬁelds accept values in the range 0 – 255.Certain types of IP packets, such as voice or multimedia packets, are sensitive to latency introduced by the network. A delay-sensitive packet is one that has the low-latency bit set in the TOS ﬁeld of the IP header. This means that if such packets are not received rapidly, the quality of service degrades. If you expect to route signiﬁcant amounts of such trafﬁc you can conﬁgure your router to route this type of trafﬁc to a gateway other than your normal gateway using this feature. The TOS ﬁeld matching check is consistent with source and destination address matching.If you check the Idle Reset checkbox, a match on this rule will keep the WAN connection alive by resetting the idle-timeout status.The Idle Reset setting is used to determine if a packet which matches the ﬁlter will cause an “instant-on” link to connect, if it is down; or reset its idle timer, if it is already up. For example, if you wanted ping trafﬁc not to keep the link up, you would create a ﬁlter which forwards a ping, but with the Idle Reset checkbox unchecked.

Administrator’s Handbook178Example: You want packets with the TOS low latency bit to go through VC 2 (via gateway 127.0.0.3 – the Motorola Netopia® Gateway will use 127.0.0.x, where x is the WAN port + 1) instead of your normal gateway.You would set up the ﬁlter as shown here.☛ NOTE:Default Forwarding FilterIf you create one or more ﬁlters that have a matching action of forward, then action on a packet matching none of the ﬁlters is to block any trafﬁc.Therefore, if the behavior you want is to force the routing of a certain type of packet and pass all others through the normal routing mechanism, you must conﬁgure one ﬁlter to match the ﬁrst type of packet and apply Force Routing. A subsequent ﬁlter is required to match and for-ward all other packets.Management IP trafﬁcIf the Force Routing ﬁlter is applied to source IP addresses, it may inadvertently block commu-nication with the router itself. You can avoid this by preceding the Force Routing ﬁlter with a ﬁl-ter that matches the destination IP address of the Gateway itself.

179Link: Security LogSecurity Monitoring is a keyed feature. See page 187 for information concerning installing Motorola Neto-pia® Software Feature Keys.Security Monitoring detects security-related events, including common types of malicious attacks, and writes them to the security log ﬁle.Using the Security Monitoring LogYou can view the Security Log at any time. Use the following steps:1. Click the Security toolbar button.2. Click the Security Log link.3. Click the Show link from the Security Log tool bar.4.

181When the Security Log contains no entries, this is the response:Timestamp BackgroundDuring bootup, to provide better log information and to support improved troubleshooting, a Motorola Neto-pia® Gateway acquires the National Institute of Standards and Technology (NIST) Universal Coordinated Time (UTC) reference signal, and then adjusts it for your local time zone.Once per hour, the Gateway attempts to re-acquire the NIST reference, for re-synchronization or initial acqui-sition of the UTC information. Once acquired, all subsequent log entries display this date and time informa-tion. UTC provides the equivalent of Greenwich Mean Time (GMT) information.If the WAN connection is not enabled (or NTP has been disabled), the internal clocking function of the Gate-way provides log timestamps based on “uptime” of the unit.The security log is empty.

Administrator’s Handbook190Link: Install CertiﬁcateSecure Sockets Layer (SSL) is a protocol for transmitting private information over the Internet. SSL uses two keys to encrypt data: a public key known to everyone and a private or secret key known only to the recipient of the message.Netopia Embedded Software Version 7.7.4 uses SSL certiﬁcates for TR-069 support.SSL certiﬁcates are issued by trusted Certiﬁcation Authorities (CAs). The CA digitally signs each certiﬁcate. Each client contains a list of trusted CAs. When an SSL handshake between a server and your Gateway occurs, the client veriﬁes that the server certiﬁcate was issued by a trusted CA. If the CA is not trusted, a warning will appear. Certiﬁcates installed in your Gateway and servers to which it connects verify to each other that communications between them are encrypted and private.Certiﬁcates are purchased from an issuing Certiﬁcate Authority, usually by your corporate IT department or other service provider, and provided to users for secure communications.You must obtain a certiﬁcate ﬁle before you can install it.1. To install an SSL certiﬁcate, click the Install Certiﬁcate link.

207CHAPTER 5 Advanced TroubleshootingAdvanced Troubleshooting can be accessed from the Gateway’s Web UI. Point your browser to http://192.168.1.254. The main page displays the device status. (If this does not make the Web UI appear, then do a release and renew in Windows networking to see what the Gateway address really is.)

Administrator’s Handbook208Home PageThe home page displays basic information about the Gateway. This includes the ISP Username, Connection Status, Device Address, Remote Gateway Address, DNS-1, and DNS-2. If you are not able to connect to the Internet, verify the following:Item DescriptionLocal WAN IP Address This is the negotiated address of the Gateway’s WAN interface. This address is usually dynamically assigned.Remote Gateway AddressThis is the negotiated address of the remote router to which this Gate-way is connected.Status of Connection ‘Waiting for DSL’ is displayed while the Gateway is training. This should change to ‘Up’ within two minutes. If not, make sure an RJ-11 cable is used, the Gateway is connected to the correct wall jack, and the Gateway is not plugged into a micro ﬁlter.‘No Connection’ is displayed if the Gateway has trained but failed the PPPoE login. This usually means an invalid user name or password. Go to Expert Mode and change the PPPoE name and password.‘Up’ is displayed when the ADSL line is synched and the PPPoE (or other connection method) session is established.‘Down’ is displayed if the line connection fails.ISP Username This should be the valid PPPoE username. If not, go to Expert Mode and change to the correct username.Device Address This is the negotiated address of the Gateway’s WAN interface. This address is often dynamically assigned. Make sure this is a valid address.If this is not the correct assigned address, go to Expert Mode and ver-ify the PPPoE address has not been manually assigned.

209Device Gateway This is the negotiated address of the remote router. Make sure this is a valid address.If this is not the correct address, go to Expert Mode and verify the address has not been manually assigned.Primary DNS/Secondary DNSThese are the negotiated DNS addresses. Make sure they are valid DNS addresses. (Secondary DNS is optional, and may validly be blank (0.0.0.0).)If these are not the correct addresses, go to Expert Mode and verify the addresses have not been manually assigned.Serial Number This is the unique serial number of your Gateway.Ethernet Status (if so equipped; not available on 3342/3342N/3352/3352N) This is the status of your Ethernet connection. If you are connecting via Ether-net, it should be Up.USB Status This is the status of your USB connection (if equipped). If you are con-necting via USB, it should be Up.Software Release This is the version number of the current embedded software in your Gateway.Warranty Date This is the date that your Gateway was installed and enabled.Date & Time If this is blank, you likely lack a network connection, or your NTP server information is incorrect.NOTE: The Home Page may also display Wireless, VoIP or Backup status depending on model and conﬁguration. See “Wireless” on page 53, “VoIP” on page 120, or “Backup” on page 133 for more information.If all of the above seem correct, then access Expert Mode by clicking the Expert Mode link.Item Description

Administrator’s Handbook210Button: TroubleshootExpert ModeExpert Mode has advanced troubleshooting tools that are used to pinpoint the exact source of a problem. Clicking the Troubleshoot tab displays a page with links to System Status, Network Tools, and Diagnostics.•System Status: Displays an overall view of the system and its condition.•Network Tools: Includes NSLookup, Ping and TraceRoute.•Diagnostics: Runs a multi-layer diagnostic test that checks the LAN, WAN, PPPoE, and other connection issues.

211Link: System StatusIn the system status screen, there are several utilities that are useful for troubleshooting. Some examples are given in the following pages.

Administrator’s Handbook212Link: Ports: EthernetThe Ethernet port selection shows the trafﬁc sent and received on the Ethernet interface. There should be frames and bytes on both the upstream and downstream sides. If there are not, this could indicate a bad Ethernet cable or no Ethernet connection. Below is an example:Ethernet Driver Statistics - 10/100 EthernetType: 100BASETPort Status: Link up General: Transmit OK : 7862 Receive OK : 4454 Tx Errors : 0 Rx Errors : 0 Rx CRC Errors : 0 Rx Frame Errors : 0Upper Layers: Rx No Handler : 0 Rx No Message : 0 Rx Octets : 975576 Rx Unicast Pkts : 4156 Rx Multicast Pkts : 203 Tx Discards : 0 Tx Octets : 2117992 Tx Unicast Pkts : 3789 Tx Multicast Pkts : 4073Ethernet driver statistics - USBPort Status: Link downGeneral: Transmit OK : 0 Receive OK : 0 Tx Errors : 0 Rx Errors : 0 Tx Octets : 0 Rx Octets : 0Ethernet driver statistics - 10/100 EthernetType: 100BASETPort Status: Link up General: Transmit OK : 7863 Receive OK : 4458 Tx Errors : 0 Rx Errors : 0 Rx CRC Errors : 0 Rx Frame Errors : 0Upper Layers: Rx No Handler : 0 Rx No Message : 0 Rx Octets : 976327 Rx Unicast Pkts : 4159 Rx Multicast Pkts : 204 Tx Discards : 0

213Link: Ports: DSLThe DSL port selection shows the state of the DSL line, whether it is up or down and how many times the Gateway attempted to train. The state should indicate ‘up’ for a working conﬁguration. If it is not, check the DSL cable and make sure it is plugged in correctly and not connected to a micro ﬁlter. Below is an example: ADSL Line State: Up ADSL Startup Attempts: 5 ADSL Modulation: DMT Datapump Version: 3.22 Downstream Upstream ---------- ---------- SNR Margin: 18.6 14.0 dB Line Attenuation: 0.4 4.0 dB Errored Seconds: 14 3 Loss of Signal: 4 4 Loss of Frame: 0 0 CRC Errors: 0 0 Data Rate: 8000 800

Administrator’s Handbook214Link: IP: InterfacesThe IP interfaces selection shows the state and conﬁguration information for your IP LAN and WAN inter-faces. Below is an example:IP interfaces:Ethernet 100BT: ( up broadcast default rip-send v1 rip-receive v1 ) inet 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255 physical address 00-16-cb-39-a9-78 mtu 1500PPP over Ethernet vcc1: ( up address-mapping broadcast default admin-disabled rip-send v1 rip-receive v1 ) inet 10.1.2.34 netmask 255.255.255.0 broadcast 10.1.2.1 physical address 00-15-bc-28-b8-67 mtu 1500

215Link: DSL: Circuit ConﬁgurationThe DSL Circuit Conﬁguration screen shows the trafﬁc sent and received over the DSL line as well as the trained rate (upstream and downstream) and the VPI/VCI. Verify trafﬁc is being sent over the DSL line. If not, check the cabling and make sure the Gateway is not connected to a micro ﬁlter.

Administrator’s Handbook218Link: Network ToolsThree test tools are available from this page.•NSLookup - converts a domain name to its IP address and vice versa.•Ping - tests the “reachability” of a particular network destination by sending an ICMP echo request and waiting for a reply.•TraceRoute - displays the path to a destination by showing the number of hops and the router addresses of these hops.1. To use the NSLookup capability, type an address (domain name or IP address) in the text box and click the NSLookup buttonExample: Show the IP Address for grosso.com. Result: The DNS Server doing the lookup is displayed in the Server: and Address: ﬁelds. If the Name Server can ﬁnd your entry in its table, it is displayed in the Name: and Address: ﬁelds.PING: The network tools section sends a PING from the Gateway to either the LAN or WAN to verify connec-tivity. A PING could be either an IP address (163.176.4.32) or Domain Name (www.netopia.com).2. To use the Ping capability, type a destination address (domain name or IP address) in the text box and click the Ping button.Example: Ping to grosso.com.Server : controller2.netopia.comAddress : 143.137.137.9Name : www.grosso.comAddress : 192.150.14.120

219Result: The host was reachable with four out of ﬁve packets sent. ping www.grosso.comPinging 192.150.14.120 from local address 143.137.199.8 (timer gran. 100 ms)...

223CHAPTER 6 Command Line InterfaceThe Motorola Netopia® Gateway operating software includes a command line interface (CLI) that lets you access your Motorola Netopia® Gateway over a telnet connection. You can use the command line interface to enter and update the unit’s conﬁguration settings, monitor its performance, and restart it.This chapter covers the following topics:•“Overview” on page 224•“Starting and Ending a CLI Session” on page 226•“Using the CLI Help Facility” on page 226•“About SHELL Commands” on page 227•“SHELL Commands” on page 228•“About CONFIG Commands” on page 240•“CONFIG Commands” on page 243CONFIG Commands“Remote ATA Conﬁguration Commands” on page 243 “PPPoE with IPoE Settings” on page 282“DSL Commands” on page 245 “Ethernet Por t Settings” on page 283“Bridging Settings” on page 246 “802.3ah Ethernet OAM Settings” on page 284“DHCP Settings” on page 248 “Command Line Interface Preference Settings” on page 285“DMT Settings” on page 254 “Port Renumbering Settings” on page 286“Domain Name System Settings” on page 255 “Security Settings” on page 287“IGMP Settings” on page 257 “System Settings” on page 298“IP Settings” on page 259 “Syslog” on page 301“Queue Conﬁguration” on page 271 “Wireless Settings (supported models)” on page 303“IPMaps Settings” on page 277 “VLAN Settings” on page 311“Network Address Translation (NAT) Default Settings” on page 278“VoIP settings” on page 316“Network Address Translation (NAT) Pinhole Settings” on page 278“UPnP settings” on page 321“PPPoE /PPPoA Settings” on page 279 “DSL Forum settings” on page 321“SNMP Settings” on page 297 “Backup IP Gateway Settings” on page 323

Administrator’s Handbook224OverviewThe CLI has two major command modes: SHELL and CONFIG. Summary tables that list the commands are provided below. Details of the entire command set follow in this section.SHELL CommandsCommand Status and/or Descriptionarp to send ARP requestatmping to send ATM OAM loopbackclear to erase all stored conﬁguration informationclear_certiﬁcate to remove an SSL certiﬁcate that has been installedclear_log to erase all stored log info in ﬂash memoryconﬁgure to conﬁgure unit's optionsdiagnose to run self-testdownload to download conﬁg ﬁleetheroam to show Ethernet OAM infoexit to quit this shellhelp to get more: “help all” or “help help”install to download and program an image into ﬂashlicense to enter an upgrade key to add a featurelog to add a message to the diagnostic logloglevel to report or change diagnostic log levelnetstat to show IP informationnslookup to send DNS query for hostping to send ICMP Echo requestquit to quit this shellreset to reset subsystemsrestart to restart unitshow to show system informationstart to start subsystemstatus to show basic status of unittelnet to telnet to a remote hosttraceroute to send traceroute probesupload to upload conﬁg ﬁleview to show conﬁguration informationvoip to show VoIP infowho to show who is using the shell

Administrator’s Handbook226Starting and Ending a CLI SessionOpen a telnet connection from a workstation on your network.You initiate a telnet connection by issuing the following command from an IP host that supports telnet, for example, a personal computer running a telnet application such as NCSA Telnet.telnet <ip_address>You must know the IP address of the Motorola Netopia® Gateway before you can make a telnet connection to it. By default, your Motorola Netopia® Gateway uses 192.168.1.254 as the IP address for its LAN inter-face. You can use a Web browser to conﬁgure the Motorola Netopia® Gateway IP address.Logging InThe command line interface log-in process emulates the log-in process for a UNIX host. To logon, enter the username (either admin or user), and your password.•Entering the administrator password lets you display and update all Motorola Netopia® Gateway set-tings. •Entering a user password lets you display (but not update) Motorola Netopia® Gateway settings. When you have logged in successfully, the command line interface lists the username and the security level associated with the password you entered in the diagnostic log.Ending a CLI SessionYou end a command line interface session by typing quit from the SHELL node of the command line inter-face hierarchy.Saving SettingsIn CONFIG mode, the save command saves the working copy of the settings to the Gateway. The Gateway automatically validates its settings when you save and displays a warning message if the conﬁguration is not correct.Using the CLI Help FacilityThe help command lets you display on-line help for SHELL and CONFIG commands. To display a list of the commands available to you from your current location within the command line inter face hierarchy, enter help.To obtain help for a speciﬁc CLI command, type help <command>. You can truncate the help command to h or a question mark when you request help for a CLI command.

227About SHELL CommandsYou begin in SHELL mode when you start a CLI session. SHELL mode lets you perform the following tasks with your Motorola Netopia® Gateway: •Monitor its performance •Display and reset Gateway statistics•Issue administrative commands to restart Motorola Netopia® Gateway functions SHELL PromptWhen you are in SHELL mode, the CLI prompt is the name of the Motorola Netopia® Gateway followed by a right angle bracket (>). For example, if you open a CLI connection to the Motorola Netopia® Gateway named “Netopia-3000/9437188,” you would see Netopia-3000/9437188> as your CLI prompt.SHELL Command ShortcutsYou can truncate most commands in the CLI to their shortest unique string. For example, you can use the truncated command q in place of the full quit command to exit the CLI. However, you would need to enter rese for the reset command, since the ﬁrst characters of reset are common to the restart command.The only commands you cannot truncate are restart and clear. To prevent accidental interruption of com-munications, you must enter the restart and clear commands in their entirety.You can use the Up and Down arrow keys to scroll backward and forward through recent commands you have entered. Alternatively, you can use the !! command to repeat the last command you entered.

Administrator’s Handbook228SHELL CommandsCommon Commandsarp nnn.nnn.nnn.nnnSends an Address Resolution Protocol (ARP) request to match the nnn.nnn.nnn.nnn IP address to an Ethernet hardware address.clear [yes]Clears the conﬁguration settings in a Motorola Netopia® Gateway. If you do not use the optional yes qual-iﬁer, you are prompted to conﬁrm the clear command.clear_certiﬁcateRemoves an SSL certiﬁcate that has been installed.clear_logErases the log information stored in ﬂash if persistent logging is enabled.conﬁgurePuts the command line interface into Conﬁgure mode, which lets you conﬁgure your Motorola Netopia® Gateway with Conﬁg commands. Conﬁg commands are described starting on page 225. diagnoseRuns a diagnostic utility to conduct a series of internal checks and loopback tests to verify network connec-tivity over each interface on your Motorola Netopia® Gateway. The console displays the results of each test as the diagnostic utility runs. If one test is dependent on another, the diagnostic utility indents its entry in the console window. For example, the diagnostic utility indents the Check IP connect to Ethernet (LAN) entry, since that test will not run if the Check Ethernet LAN Connect test fails. Each test generates one of the following result codes:download [server_address ] [ﬁlename] [conﬁrm]This command installs a ﬁle of conﬁguration parameters into the Motorola Netopia® Gateway from a TFTP (Trivial File Transfer Protocol) server. The TFTP server must be accessible on your Ethernet network.CODE DescriptionPASS The test was successful.FAIL The test was unsuccessful.SKIPPED The test was skipped because a test on which it depended failed, or because the test did not apply to your particular setup or model.PENDING The test timed out without producing a result. Try running the test again.

229You can include one or more of the following arguments with the download command. If you omit argu-ments, the console prompts you for this information.•The server_address argument identiﬁes the IP address of the TFTP server from which you want to copy the Motorola Netopia® Gateway conﬁguration ﬁle. •The filename argument identiﬁes the path and name of the conﬁguration ﬁle on the TFTP server. •If you include the optional conﬁrm keyword, the download begins as soon as all information is entered.You can also download an SSL certiﬁcate ﬁle from a trusted Certiﬁcation Authority (CA), on platforms that support SSL, as follows:download [-cert] [server_address ] [ﬁlename] [conﬁrm]install [server_address] [ﬁlename] [conﬁrm](Not supported on model 3342/3352)Downloads a new version of the Motorola Netopia® Gateway operating software from a TFTP (Trivial File Transfer Protocol) server, validates the software image, and programs the image into the Motorola Neto-pia® Gateway memory. After you install new operating software, you must restart the Motorola Netopia® Gateway.The server_address argument identiﬁes the IP address of the TFTP server on which your Motorola Neto-pia® Gateway operating software is stored. The filename argument identiﬁes the path and name of the operating software ﬁle on the TFTP server.If you include the optional keyword confirm, you will not be prompted to conﬁrm whether or not you want to perform the operation.license [key]This command installs a software upgrade key. An upgrade key is a purchased item, based on the serial number of the gateway.log message_stringAdds the message in the message_string argument to the Motorola Netopia® Gateway diagnostic log.loglevel [level] Displays or modiﬁes the types of log messages you want the Motorola Netopia® Gateway to record. If you enter the loglevel command without the optional level argument, the command line interface dis-plays the current log level setting. You can enter the loglevel command with the level argument to specify the types of diagnostic mes-sages you want to record. All messages with a level number equal to or greater than the level you specify are recorded. For example, if you specify loglevel 3, the diagnostic log will retain high-level informational messages (level 3), warnings (level 4), and failure messages (level 5).Use the following values for the level argument:

$Administrator’s Handbook230•1 or low – Low-level informational messages or greater; includes trivial status messages.•2 or medium – Medium-level informational messages or greater; includes status messages that can help monitor network trafﬁc.•3 or high – High-level informational messages or greater; includes status messages that may be signif-icant but do not constitute errors.•4 or warning – Warnings or greater; includes recoverable error conditions and useful operator infor-mation.•5 or failure – Failures; includes messages describing error conditions that may not be recover-able. netstat -i Displays the IP interfaces for your Motorola Netopia® Gateway.netstat -r Displays the IP routes stored in your Motorola Netopia® Gateway.nslookup { hostname | ip_address }Performs a domain name system lookup for a speciﬁed host.•The hostname argument is the name of the host for which you want DNS information; for example, nslookup klaatu.•The ip_address argument is the IP address, in dotted decimal notation, of the device for which you want DNS information.ping [-s size] [-c count]{ hostname | ip_address }Causes the Motorola Netopia® Gateway to issue a series of ICMP Echo requests for the device with the speciﬁed name or IP address. •The hostname argument is the name of the device you want to ping; for example, ping ftp.neto-pia.com.•The ip_address argument is the IP address, in dotted decimal notation, of the device you want to locate. If a host using the speciﬁed name or IP address is active, it returns one or more ICMP Echo replies, conﬁrming that it is accessible from your network.•The -s size argument lets you specify the size of the ICMP packet.•The -c count argument lets you specify the number of ICMP packets generated for the ping request. Values greater than 250 are truncated to 250.You can use the ping command to determine whether a hostname or IP address is already in use on your network. You cannot use the ping command to ping the Motorola Netopia® Gateway’s own IP address.quit Exits the Motorola Netopia® Gateway command line interface.$

231reset arp Clears the Address Resolution Protocol (ARP) cache on your unit.reset atmResets the Asynchronous Transfer Mode (ATM) statistics.reset cdmodeThis command will set up one boot ﬂag so that the next time a 3342N/3352N restarts or reboots (power cycle), the Gateway will boot into CD-ROM mode instead of Gateway mode.This command is only for the 3342N/3352N. If the Gateway is not a 3342N/3352N this command does nothing but returns the message: "CD mode is not supported on this platform."reset crash Clears crash-dump information, which identiﬁes the contents of the Motorola Netopia® Gateway registers at the point of system malfunction.reset dhcp serverClears the DHCP lease table in the Motorola Netopia® Gateway.reset diffservResets the Differentiated Services (diffserv) statistics.reset enet [ all ]Resets Ethernet statistics to zero. Resets individual LAN switch port statistics as well as wireless and WAN Ethernet statistics (where applicable).reset heartbeatRestarts the heartbeat sequence.reset ipmapClears the IPMap table (NAT).reset logRewinds the diagnostic log display to the top of the existing Motorola Netopia® Gateway diagnostic log. The reset log command does not clear the diagnostic log. The next show log command will display infor-mation from the beginning of the log ﬁle.

Administrator’s Handbook232reset security-logClears the security monitoring log to make room to capture new entries. reset wan-users [all | ip-address]This function disconnects the speciﬁed WAN User to allow for other users to access the WAN. This function is only available if the number of WAN Users is restricted and NAT is on. Use the all parameter to discon-nect all users. If you logon as Admin you can disconnect any or all users. If you logon as User, you can only disconnect yourself.reset wanThis function resets WAN interface statistics.reset wepkeysThis function allows you to force your wireless WEP key settings back to the default values, if there are default values. For example, on some models, the WEP keys are based on the serial number. This allows you to get back those default settings if you have changed them without the need to reset the entire conﬁg-uration of the unit.restart [seconds]Restarts your Motorola Netopia® Gateway. If you include the optional seconds argument, your Motorola Netopia® Gateway will restart when the speciﬁed number of seconds have elapsed. You must enter the complete restart command to initiate a restart.show all-infoDisplays all settings currently conﬁgured in the Motorola Netopia® Gateway.show backupDisplays the status of the Backup port, Up or Down, and reports the current port in use.show bridge interfacesDisplays bridge interfaces maintained by the Motorola Netopia® Gateway.show bridge tableDisplays the bridging table maintained by the Motorola Netopia® Gateway.show conﬁgDumps the Motorola Netopia® Gateway’s conﬁguration script just as the script command does in conﬁg mode.

You can display a subset of the PPP statistics by including an optional stats, lcp, or ipcp argument for the show ppp command.start ppp vccnOpens a PPP link on the speciﬁed virtual circuit.About CONFIG CommandsYou reach the conﬁguration mode of the command line interface by typing conﬁgure (or any truncation of conﬁgure, such as con or conﬁg) at the CLI SHELL prompt.CONFIG Mode PromptWhen you are in CONFIG mode, the CLI prompt consists of the name of the Motorola Netopia® Gateway fol-lowed by your current node in the hierarchy and two right angle brackets (>>). For example, when you enter CONFIG mode (by typing conﬁg at the SHELL prompt), the Netopia-3000/9437188 (top)>> prompt reminds you that you are at the top of the CONFIG hierarchy. If you move to the ip node in the CON-FIG hierarchy (by typing ip at the CONFIG prompt), the prompt changes to Netopia-3000/9437188 (ip)>> to identify your current location.Some CLI commands are not available until certain conditions are met. For example, you must enable IP for an interface before you can enter IP settings for that interface.Navigating the CONFIG Hierarchy•Moving from CONFIG to SHELL — You can navigate from anywhere in the CONFIG hierarchy back to the SHELL level by entering quit at the CONFIG prompt and pressing RETURN. Netopia-3000/9437188 (top)>> quitNetopia-3000/9437188 >•Moving from top to a subnode — You can navigate from the top node to a subnode by entering the node name (or the signiﬁcant letters of the node name) at the CONFIG prompt and pressing RETURN. For example, you move to the IP subnode by entering ip and pressing RETURN.Netopia-3000/9437188 (top)>> ipNetopia-3000/9437188 (ip)>>As a shortcut, you can enter the signiﬁcant letters of the node name in place of the full node name at the CONFIG prompt. The signiﬁcant characters of a node name are the letters that uniquely identify the node. For example, since no other CONFIG node starts with b, you could enter one letter (“b”) to move to the bridge node.•Jumping down several nodes at once — You can jump down several levels in the CONFIG hierarchy by entering the complete path to a node. •Moving up one node — You can move up through the CONFIG hierarchy one node at a time by entering the up command.

241•Jumping to the top node — You can jump to the top level from anywhere in the CONFIG hierarchy by entering the top command. •Moving from one subnode to another — You can move from one subnode to another by entering a partial path that identiﬁes how far back to climb.•Moving from any subnode to any other subnode — You can move from any subnode to any other subnode by entering a partial path that starts with a top-level CONFIG command.•Scrolling backward and forward through recent commands — You can use the Up and Down arrow keys to scroll backward and forward through recent commands you have entered. When the command you want appears, press Enter to execute it.Entering Commands in CONFIG ModeCONFIG commands consist of keywords and arguments. Keywords in a CONFIG command specify the action you want to take or the entity on which you want to act. Arguments in a CONFIG command specify the val-ues appropriate to your site. For example, the CONFIG commandset ip ethernet A ip_address consists of two keywords (ip, and ethernet A) and one argument (ip_address). When you use the command to conﬁgure your Gateway, you would replace the argument with a value appropriate to your site.For example:set ip ethernet A 192.31.222.57Guidelines: CONFIG CommandsThe following table provides guidelines for entering and formatting CONFIG commands.If a command is ambiguous or miskeyed, the CLI prompts you to enter additional information. For example, you must specify which virtual circuit you are conﬁguring when you are setting up a Motorola Netopia® Gateway.Command component Rules for entering CONFIG commandsCommand verbs CONFIG commands must start with a command verb (set, view, delete).You can truncate CONFIG verbs to three characters (set, vie, del).CONFIG verbs are case-insensitive. You can enter “SET,” “Set,” or “set.”Keywords Keywords are case-insensitive. You can enter “Ethernet,” “ETHERNET,” or “ethernet” as a keyword without changing its meaning.Keywords can be abbreviated to the length that they are differentiated from other keywords. Argument Text Text strings can be as many as 64 characters long, unless otherwise speci-ﬁed. In some cases they may be as long as 255 bytes.Special characters are represented using backslash notation.Text strings may be enclosed in double (“) or single (‘) quote marks. If the text string includes an embedded space, it must be enclosed in quotes.Special characters are represented using backslash notation.Numbers Enter numbers as integers, or in hexadecimal, where so noted.IP addresses Enter IP addresses in dotted decimal notation (0 to 255).

Administrator’s Handbook242Displaying Current Gateway SettingsYou can use the view command to display the current CONFIG settings for your Motorola Netopia® Gate-way. If you enter the view command at the top level of the CONFIG hierarchy, the CLI displays the settings for all enabled functions. If you enter the view command at an intermediate node, you see settings for that node and its subnodes.Step Mode: A CLI Conﬁguration TechniqueThe Motorola Netopia® Gateway command line interface includes a step mode to automate the process of entering conﬁguration settings. When you use the CONFIG step mode, the command line interface prompts you for all required and optional information. You can then enter the conﬁguration values appropriate for your site without having to enter complete CLI commands.When you are in step mode, the command line interface prompts you to enter required and optional set-tings. If a setting has a default value or a current setting, the command line interface displays the default value for the command in parentheses. If a command has a limited number of acceptable values, those val-ues are presented in brackets, with each value separated by a vertical line. For example, the following CLI step command indicates that the default value is off and that valid entries are limited to on and off.option (off) [on | off]: onYou can accept the default value for a ﬁeld by pressing the Return key. To use a different value, enter it and press Return.You can enter the CONFIG step mode by entering set from the top node of the CONFIG hierarchy. You can enter step mode for a particular service by entering set service_name. In stepping set mode (press Control-X <Return/Enter> to exit. For example:Netopia-3000/9437188 (top)>> set system...system name (“Netopia-3000/9437188”): Mycroft Diagnostic Level (High): mediumStepping mode ended.Validating Your ConﬁgurationYou can use the validate CONFIG command to make sure that your conﬁguration settings have been entered correctly. If you use the validate command, the Motorola Netopia® Gateway veriﬁes that all required settings for all services are present and that settings are consistent.Netopia-3000/9437188 (top)>> validateError: Subnet mask is incorrectGlobal Validation did not pass inspection!You can use the validate command to verify your conﬁguration settings at any time. Your Motorola Neto-pia® Gateway automatically validates your conﬁguration any time you save a modiﬁed conﬁguration.

243CONFIG CommandsThis section describes the keywords and arguments for the various CONFIG commands.Remote ATA Conﬁguration CommandsMotorola Netopia® ﬁrmware supports conﬁguration of a maximum of four Motorola Netopia® ATA proﬁles, which are stored in the Gateway’s conﬁguration database. When a Motorola Netopia® ATA is discovered, the Gateway compares the MAC address of the ATA with one of the existing proﬁles stored in the database. If there is a match, the conﬁguration is downloaded to the Motorola Netopia® ATA, and the ATA is restarted. Once the Motorola Netopia® ATA is restarted, it comes up with the newly downloaded conﬁguration.set ata proﬁle [ 0... 3 ] ata-option [ on | off ]Enables or disables the remote ATA conﬁguration option for the speciﬁed ATA conﬁguration proﬁle to be stored in the Gateway.set ata proﬁle [ 0... 3 ] ata-mac-addr MAC_addrSpeciﬁes the MAC address of the ATA for the speciﬁed conﬁguration proﬁle.set ata proﬁle [ 0... 3 ] ata-qos-enable [ on | off ]Enables or disables QoS for the speciﬁed proﬁle.set ata proﬁle [ 0... 3 ] ata-dhcpc-enable [ on | off ]Enables or disables DHCP client service for the speciﬁed proﬁle.set ata proﬁle [ 0... 3 ] ata-dhcpc-hostname stringSpeciﬁes a DHCP client hostname for the speciﬁed proﬁle.set ata proﬁle [ 0... 3 ] ata-dhcpc-vid-enable [ off | on ]Enables or disables a DHCP client vendor ID for the speciﬁed proﬁle.set ata proﬁle [ 0... 3 ] ata-dhcpc-vid stringSpeciﬁes a vendor ID for the speciﬁed proﬁle when ata-dhcpc-vid-enable is on.set ata proﬁle [ 0... 3 ] ata-static-wan-ip ip_addrSpeciﬁes a static WAN IP address for the speciﬁed proﬁle.set ata proﬁle [ 0... 3 ] ata-static-wan-subnet-mask subnet_maskSpeciﬁes a static WAN IP subnet mask for the speciﬁed proﬁle.

245DSL CommandsATM Settings. You can use the CLI to set up each ATM virtual circuit. set atm option {on | off } Enables the WAN interface of the Motorola Netopia® Gateway to be conﬁgured using the Asynchronous Transfer Mode (ATM) protocol.set atm [vcc n] option {on | off } Selects the virtual circuit for which further parameters are set. Up to eight VCCs are supported; the maxi-mum number is dependent on your Motorola Netopia® Operating System tier and the capabilities that your Service Provider offers.set atm [vcc n] qos service-class { cbr | ubr | vbr }Sets the Quality of Service class for the speciﬁed virtual circuit – Constant (cbr), Unspeciﬁed (ubr), or Vari-able (vbr) Bit Rate. •ubr: No conﬁguration is needed for UBR VCs. Leave the default value 0 (maximum line rate).•cbr: One parameter is required for CBR VCs. Enter the Peak Cell Rate that applies to the VC. This value should be between 1 and the line rate. You set this value according to speciﬁcations deﬁned by your ser-vice provider.•vbr: Three parameters are required for VBR VCs. Enter the Peak Cell Rate, the Sustained Cell Rate, and the Maximum Burst Size that apply to the VC. You set these values according to speciﬁcations deﬁned by your service provider.set atm [vcc n] qos peak-cell-rate { 1 ...n }If QoS class is set to cbr or vbr then specify the peak-cell-rate that should apply to the speciﬁed virtual circuit. This value should be between 1 and the line rate.The Peak Cell Rate (PCR) should be set to the maximum rate a PVC can oversubscribe its Sustained Cell Rate (SCR). The Peak Cell Rate (see below) must be less than, or equal to the raw WAN (DSL) bit rate. The Maximum Burst Size (MBS) is the number of cells that can be sent at the PCR rate, after which the PVC must fall back to the SCR rate.set atm [vcc n] qos sustained-cell-rate { 1 ...n }If QoS class is set to vbr, then specify the sustained-cell-rate that should apply to the speciﬁed virtual cir-cuit. This value should be less than, or equal to the Peak Cell Rate, which should be less than, or equal to the line rate.set atm [vcc n] qos max-burst-size { 1 ...n }If QoS class is set to vbr then specify the max-burst-size that should apply to the speciﬁed virtual circuit. This value is the maximum number of cells that can be transmitted at the Peak Cell Rate after which the ATM VC transmission rate must drop to the Sustained Cell Rate.

The total number of pppoe-sessions and PPPoE VCCs conﬁgured must be less than or equal to eight.Bridging SettingsBridging lets the Motorola Netopia® Gateway use MAC (Ethernet hardware) addresses to forward non-TCP/IP trafﬁc from one network to another. When bridging is enabled, the Motorola Netopia® Gateway maintains a table of up to 512 MAC addresses. Entries that are not used within 30 seconds are dropped. If the bridg-ing table ﬁlls up, the oldest table entries are dropped to make room for new entries. Virtual circuits that use IP framing cannot be bridged.☛ NOTE:For bridging in the 3341 (or any model with a USB port), you cannot set the bridge option off, or bridge ethernet option off; these are on by default because of the USB port.ppp-vcmux PPP over ATM, VC-muxedppp-llc PPP over ATM, LLC-SNAPether-llc RFC-1483, bridged Ethernet, LLC-SNAPip-llc RFC-1483, routed IP, LLC-SNAPpppoe-vcmux PPP over Ethernet, VC-muxedpppoe-llc PPP over Ethernet, LLC-SNAP

Default = 30 secs; range = 30 secs – 6000 secs (.5–100 mins).

$Administrator’s Handbook248DHCP SettingsAs a Dynamic Host Control Protocol (DHCP) server, your Motorola Netopia® Gateway can assign IP addresses and provide conﬁguration information to other devices on your network dynamically. A device that acquires its IP address and other TCP/IP conﬁguration settings from the Motorola Netopia® Gateway can use the information for a ﬁxed period of time (called the DHCP lease).Common Commandsset dhcp option { off | server | relay-agent } Enables or disables DHCP services in the Motorola Netopia® Gateway. You must enable DHCP services before you can enter other DHCP settings for the Motorola Netopia® Gateway.If you turn off DHCP services and save the new conﬁguration, the Motorola Netopia® Gateway clears its DHCP settings.set dhcp start-address ip_address If you selected server, speciﬁes the ﬁrst address in the DHCP address range. The Motorola Netopia® Gateway can reserve a sequence of up to 253 IP addresses within a subnet, beginning with the speciﬁed address for dynamic assignment. set dhcp end-address ip_address If you selected server, speciﬁes the last address in the DHCP address range.set dhcp lease-time lease-time If you selected server, speciﬁes the default length for DHCP leases issued by the Motorola Netopia® Gateway. Enter lease time in dd:hh:mm:ss (day/hour/minute/second) format.set dhcp option-group nameSpeciﬁes a name for one of up to eight DHCP Option Groups. Each Option Group can have a name of between 1 and 15 characters. The name is used in the DHCP ﬁlterset syntax to choose what group of gen-options is to be served to a particular DHCP Client. See “DHCP Generic Options” on page 249 and “DHCP Option Filtering” on page 252.Option Groups refer to gen-options; they do not contain them. Deleting a gen-option from an option group does not delete the option. Adding a gen-option to an option-group does not preclude it from being added to another option-group. set dhcp default-option-group nameSets the option group speciﬁed by name as the default.set dhcp server-address ip_address If you selected relay-agent, speciﬁes the IP address of the relay agent server.$

249set dhcp range [ 2... 8 ] start-address ip_addressSpeciﬁes the starting IP address of DHCP range n when subnet n option is on. See “Additional subnets” on page 262.set dhcp range [ 2... 8 ] end-address ip_addressSpeciﬁes the ending IP address of DHCP range n when subnet n option is on. See “Additional subnets” on page 262.set dhcp reserved ip-address x.x.x.x mac-address y-y-y-y-y-yIf you selected server, reserves the speciﬁed IP address from the DHCP pool to the speciﬁed MAC address. These are list items; a total of 16 reserved addresses are supported. Secondary ranges will all make use of the dhcp lease-time value.DHCP Generic OptionsBeginning with Firmware Version 7.7.2, you can specify DHCP Generic Options which allow you to conﬁgure the content to be served for particular option numbers.set dhcp gen-option name nameSpeciﬁes a DHCP generic option set named name of one to 15 characters. You can specify up to 20 gen-options. Each can contain up to 100 bytes of data, up to a maximum of 912 bytes of options data total. An option will be served only if the client requests it.set dhcp gen-option option [ 1 – 255 ]Speciﬁes the DHCP option by number, 1 – 255.

Administrator’s Handbook252DHCP Option FilteringBeginning with Firmware Version 7.7, support for DHCP option ﬁltering is provided via the ﬁlterset settings.set dhcp ﬁlterset name "string" rule n type [ dhcp-option | hw-address | requested-option ]Speciﬁes a DHCP ﬁlterset named string as one of three possible types: The rule can either specify an option and option contents, dhcp-option; a client hardware address range, hw-address; or an option the client is requesting, requested-option. For hw-address, you will need to enter start-address and end-address values; for the others a dhcp-option parameter must be set.By default a rule is of type dhcp-option, for backwards compatibility.set dhcp ﬁlterset name "string" rule n dhcp-option [ 0... 255 ]Creates a DHCP ﬁlterset named string, for example “settopbox,” with rule number n.Up to two ﬁltersets can be added. Your Gateway supports a single LAN DHCP server instance, but an addi-tional ﬁlterset is available for use when bridging, to block undesired DHCP trafﬁc. Up to 8 rules can be cre-ated in the ﬁlterset, which are evaluated in order.dhcp-option determines which DHCP option should be compared. A typical value would be to use option 60 data for comparison, but allowing this value to be conﬁgured permits more ﬂexibility.set dhcp ﬁlterset name "settopbox" rule 1 type dhcp-optionset dhcp ﬁlterset name "string" rule n match-action [ pass | discard | continue ]Assigns a match action to the ﬁlterset. If set to pass the match-pool address is shown. set dhcp ﬁlterset name "string" rule n absent-action [ pass | discard | continue ] Assigns an absent action to the ﬁlterset. If set to pass the absent-pool address is hidden.set dhcp ﬁlterset name "string" rule n match-option-group "option_group*"Assigns the option group named option_group to match.set dhcp ﬁlterset name "string" rule n match-str "match_string*"Assigns a match string to the ﬁlterset. The match-str string will be compared against the DHCP DISCOVER option data. This string can contain multiple “*” and “?” wildcard substitutions.

253set dhcp ﬁlterset name "string" rule n match-pool ip_addressSpeciﬁes the start IP address of the range within a DHCP pool where that range will be used to allocate an address if the wildcard matches.The value 0.0.0.0 means regular processing; 255.255.255.255 means discard.set dhcp ﬁlterset name "string" rule n absent-pool ip_addressSpeciﬁes the start IP address of the range within a DHCP pool where that range will be used to allocate an address if the option in the DHCP packet is not present.The value 0.0.0.0 means regular processing; 255.255.255.255 means discard.ExampleNetopia-3000/9450000 (dhcp)>> scset dhcp option serverset dhcp start-address 192.168.1.33set dhcp end-address 192.168.1.63set dhcp lease-time 01:00:00:00set dhcp filterset name "settopbox" rule 1 dhcp-option 60set dhcp filterset name "settopbox" rule 1 match-str "STB*"set dhcp filterset name "settopbox" rule 1 match-pool 192.168.6.100set dhcp filterset name "settopbox" rule 1 absent-pool 0.0.0.0Netopia-3000/9450000 (dhcp)>>set dhcp assigned-ﬁlterset "string"Assigns the ﬁlterset named string created above to the DHCP conﬁguration.

Administrator’s Handbook254DMT SettingsDSL Commandsset dmt dsl-annex-support [ off | on ]This controls whether other annex support (just as Annex M) is enabled. Default is off.set dmt type [ lite | dmt | ansi | multi | adsl2 | adsl2+ | readsl2 | adsl2anxm | adsl2+anxm ] Selects the type of Discrete Multitone (DMT) asynchronous digital subscriber line (ADSL) protocol to use for the WAN interface.The type value also supports the following settings on certain model units: adsl2, adsl2+, readsl2, adsl2anxm, adsl2+anxm.☛ NOTE:Some dmt type settings are now supported for many Annex B (335xN) platforms. 2200 Series and 33xxN Series models are supported. Currently, adsl2anxm and adsl2+anxm are not sup-ported in Annex B.set dmt autoConﬁg [ off | on ]Enables support for automatic VPI/VCI detection and conﬁguration. When set to on (the default), a pre-deﬁned list of VPI/VCI pairs are searched to ﬁnd a valid conﬁguration for your ADSL line. Entering a value for the VPI or VCI setting will disable this feature.set dmt dmt dying-gasp [ default | off | on ]Enables or disables Gateway “dying gasp” behavior in cases of power failure. Default is off.set dmt wiringMode [ auto | tip_ring | A_A1 ](not supported on all models) This command conﬁgures the wiring mode setting for your ADSL line. Select-ing auto (the default) causes the Gateway to detect which pair of wires (inner or outer pair) are in use on your phone line. Specifying tip_ring forces the inner pair to be used; and A_A1 the outer pair.set dmt metallic-termination [ auto | disabled | always_on ](not supported on all models) This command allows you to apply a sealing current to “dry” DSL lines so that the wiring doesn’t corrode.•auto - The device will scan for standard telephone service (POTS). If it ﬁnds POTS, it disables metallic termination. If it does not ﬁnd POTS during the search period, then metallic termination is enabled.•disabled - There is no POTS detection, and metallic termination is disabled.•always_on - The device will scan for POTS for information only. Metallic termination is always enabled.

255Domain Name System SettingsDomain Name System (DNS) is an information service for TCP/IP networks that uses a hierarchical naming system to identify network domains and the hosts associated with them. You can identify a primary DNS server and one secondary server.Common Commandsset dns domain-name domain-name Speciﬁes the default domain name for your network. When an application needs to resolve a host name, it appends the default domain name to the host name and asks the DNS server if it has an address for the “fully qualiﬁed host name.” set dns primary-address ip_address Speciﬁes the IP address of the primary DNS name server. set dns proxy-enableThis allows you to disable the default behavior of acting as a DNS proxy. The default is on.set dns secondary-address ip_addressSpeciﬁes the IP address of the secondary DNS name server. Enter 0.0.0.0 if your network does not have a secondary DNS name server.set dns conﬁgured-dns-priority [ 0 - 255 ]Sets the conﬁgured DNS priority relative to acquired DNS. These server addresses may be acquired via DHCP (client), PPP, or statically conﬁgured. A “DNS learned-server-priority” is assigned to each conﬁgured interface. By default, conﬁgured DNSes have the highest priority (lowest number), then PPP-acquired DNSes, and DHCP-acquired DNSes have lowest priority (highest number).The default priorities for each type are:•Conﬁgured DNSes: 10•PPP-acquired: 20•DHCP-acquired: 30

Administrator’s Handbook256Dynamic DNS SettingsDynamic DNS support allows you to use the free services of www.dyndns.org. Dynamic DNS automatically directs any public Internet request for your computer's name to your current dynamically-assigned IP address. This allows you to get to the IP address assigned to your Gateway, even though your actual IP address may change as a result of a PPPoE connection to the Internet.set dynamic-dns option [ off | dyndns.org ]set dynamic-dns ddns-host-name myhostname.dyndns.orgset dynamic-dns ddns-user-name myusernameset dynamic-dns ddns-user-password myuserpasswordEnables or disables dynamic DNS services. The default is off. If you specify dyndns.org, you must supply your hostname, username for the service, and password.Because different dynamic DNS vendors use different proprietary protocols, currently only www.dyndns.org is supported.

257IGMP SettingsNOTE: IGMP Version 3 is supported beginning with Firmware Version 7.7.See “IGMP (Internet Group Management Protocol)” on page 100 for detailed explanation.You can set the following options:•IGMP Snooping – enables the Motorola Netopia® Gateway to “listen in” to IGMP trafﬁc. The Gateway discovers multicast group membership for the purpose of restricting multicast transmissions to only those ports which have requested them. This helps to reduce overall network trafﬁc from streaming media and other bandwidth-intensive IP multicast applications.•Robustness – a way of indicating how sensitive to lost packets the network is. IGMP can recover from robustness minus 1 lost IGMP packet. The default value is 2.•Query Interval– the amount of time in seconds between IGMP General Query messages sent by the querier gateway. The default query interval is 125 seconds. •Query Response Interval – the maximum amount of time in tenths of a second that the IGMP router waits to receive a response to a General Query message. The default query response interval is 10 sec-onds and must be less than the query interval.•Unsolicited Report Interval – the amount of time in seconds between repetitions of a particular com-puter’s initial report of membership in a group. The default unsolicited report interval is 10 seconds.•Querier Version – select a version of the IGMP Querier: version 1, version 2, or version 3. If you know you will be communicating with other hosts that are limited to v1 or v2, for backward compatibility, select accordingly; otherwise, allow the default v3.☛ NOTE:IGMP Querier version is relevant only if the router is conﬁgured for IGMP forwarding. If any IGMP v1 routers are present on the subnet, the querier must use IGMP v1. The use of IGMP v1 must be administratively conﬁgured, since there is no reliable way of dynamically determining whether IGMP v1 routers are present on a network. IGMP forwarding is enabled per IP Proﬁle and WAN Connection Proﬁle.•Last Member Query Interval – the amount of time in tenths of a second that the IGMP gateway waits to receive a response to a Group-Speciﬁc Query message. The last member query interval is also the amount of time in seconds between successive Group-Speciﬁc Query messages. The default last mem-ber query interval is 1 second (10 deci-seconds).•Last Member Query Count – the number of Group-Speciﬁc Query messages sent before the gateway assumes that there are no members of the host group being queried on this interface. The default last member query count is 2.•Fast Leave – set to off by default, fast leave enables a non-standard expedited leave mechanism. The querier keeps track of which client is requesting which channel by IP address. When a leave message is received, the querier can check its internal table to see if there are any more clients on this group. If there are none, it immediately sends an IGMP leave message to the upstream querier.•Log Enable – If set to on, all IGMP messages on both the LAN and the WAN will be logged.•Wireless Multicast to Unicast conversion – Only available if IGMP Snooping is enabled. If set to on, the Gateway replaces the multicast MAC-address with the physical MAC-address of the wireless client. If there is more than one wireless client interested in the same multicast group, the router will revert to multicasting the stream immediately. When one or more wireless clients leave a group, and the router

Administrator’s Handbook258determines that only a single wireless client is interested in the stream, it will once again unicast the stream.set igmp snooping [ off | on ]Enables IGMP Snooping.set igmp robustness valueSets IGMP robustness range: from 2 – 255. The default is 2.set igmp query-intvl valueSets the query-interval range: from 10 seconds – 600 seconds, The default is 125 seconds.set igmp query-response-intvl valueSets the query-response interval range: from 5 deci-seconds (tenths of a second) – 255 deci-seconds. The default is 100 deci-seconds.set igmp unsol-report-intvl valueSets the unsolicited report interval: the amount of time in seconds between repetitions of a particular com-puter’s initial report of membership in a group. The default is 10 seconds.set igmp version [ 1 | 2 | 3 ]Sets the IGMP querier version: version 1, version 2, or version 3. If you know you will be communicating with other hosts that are limited to v1, for backward compatibility, select 1; otherwise, allow the default 3.set igmp last-member-query-intvl valueSets the last member query interval: the amount of time in tenths of a second that the IGMP gateway waits to receive a response to a Group-Speciﬁc Query message. The last member query interval is also the amount of time in seconds between successive Group-Speciﬁc Query messages. The default is 1 second (10 deci-seconds).set igmp last-member-query-count valueSets the last member query count: the number of Group-Speciﬁc Query messages sent before the gateway assumes that there are no members of the host group being queried on this interface. The default is 2.set igmp fast-leave [ off | on ]Sets fast leave on or off. Set to off by default, fast leave enables a non-standard expedited leave mecha-nism. The querier keeps track of which client is requesting which channel by IP address. When a leave mes-sage is received, the querier can check its internal table to see if there are any more clients on this group. If there are none, it immediately sends an IGMP leave message to the upstream querier.

$259set igmp wireless-m2u [ on | off ]This command allows you enable or disable wireless multicast-to-unicast if igmp snooping is set to on.set igmp log-enable [ on | off ]If set to on, all IGMP messages on both the LAN and the WAN will be logged. Default is off.IP SettingsYou can use the command line interface to specify whether TCP/IP is enabled, identify a default Gateway, and to enter TCP/IP settings for the Motorola Netopia® Gateway LAN and WAN ports.☛ NOTE:For the DSL platform you must identify the virtual PPP interface [vccn], a number from 1 to 8.Common Settingsset ip option { on | off }Enables or disables TCP/IP services in the Motorola Netopia® Gateway. You must enable TCP/IP services before you can enter other TCP/IP settings for the Motorola Netopia® Gateway. If you turn off TCP/IP ser-vices and save the new conﬁguration, the Motorola Netopia® Gateway clears its TCP/IP settings. ARP Timeout Settingsset ip arp-timeout [ 60 ... 6000 ]Sets the timeout value for ARP timeout. Default = 600 secs (10 mins); range = 60 secs - 6000 secs (1–100 mins).DSL Settingsset ip dsl vccn address ip_addressAssigns an IP address to the virtual circuit. Enter 0.0.0.0 if you want the virtual circuit to obtain its IP address from a remote DHCP server.set ip dsl vccn broadcast broadcast_addressSpeciﬁes the broadcast address for the TCP/IP network connected to the virtual circuit. IP hosts use the broadcast address to send messages to every host on your network simultaneously.The broadcast address for most networks is the network number followed by 255. For example, the broad-cast address for the 192.168.1.0 network would be 192.168.1.255.$

Administrator’s Handbook260set ip dsl vccn netmask netmaskSpeciﬁes the subnet mask for the TCP/IP network connected to the virtual circuit. The subnet mask speci-ﬁes which bits of the 32-bit binary IP address represents network information. The default subnet mask for most networks is 255.255.255.0 (Class C subnet mask).set ip dsl vccn restrictions { admin-disabled | none }Speciﬁes restrictions on the types of trafﬁc the Motorola Netopia® Gateway accepts over the DSL virtual circuit. The admin-disabled argument means that access to the device via telnet, web, and SNMP is disabled. RIP and ICMP trafﬁc is still accepted. The none argument means that all trafﬁc is accepted.set ip dsl vccn addr-mapping { on | off }Speciﬁes whether you want the Motorola Netopia® Gateway to use network address translation (NAT) when communicating with remote routers. Address mapping lets you conceal details of your network from remote routers. It also permits all LAN devices to share a single IP address. By default, address mapping is turned “On”.set ip dsl vccn auto-sensing [ off | dhcp/pppoe | pppoe/pppoa ]Enables or disables DHCP/PPPoE or PPPoE/PPPoA autosensing on the speciﬁed interface. Setting this to DHCP/PPPoE enables automatic sensing of your WAN connection type: PPPoE or DHCP. The gateway attempts to connect using PPPoE ﬁrst. If the Gateway fails to connect after 60 seconds, it switches to DHCP. As soon as it can connect via DHCP, the Gateway chooses and sets DHCP as its default. Otherwise, after attempting to connect via DHCP for 60 seconds, the Gateway switches back to PPPoE. The Gateway will continue to switch back and forth in this manner until it successfully connects. Similarly, selecting PPPoE/PPPoA causes the Gateway to attempt to connect by trying these protocols in parallel, and using the ﬁrst one that is successful.set ip dsl vccn mcast-fwd [ on | off }Enables or disables multi-cast forwarding on the speciﬁed interface. If set to on, this interface acts as an IGMP proxy host, and IGMP packets are transmitted and received on this interface on behalf of IGMP hosts on the LAN interface.set ip dsl vccn igmp-null-source-addr { on | off }Speciﬁes whether you want the Motorola Netopia® Gateway to identify the source IP address of every IGMP packet transmitted from this interface as 0.0.0.0 when mcast-fwd is set to on. This complies with the requirements of TR-101, and removes the need for a publicly advertised IP address on the WAN interface.set ip dsl vccn unnumbered [ on | off }Speciﬁes whether you want the Motorola Netopia® Gateway to have its WAN interface unnumbered, i.e. set to 0. unnumbered option is only available if the address is set to 0 for the interface. Enables or disables unnumbered IP addressing (where an address of 0 is allowed AND the DHCP client is disabled) on the spec-iﬁed interface. This setting applies to native IP as well as PPP inter faces to support running an IPoE inter-face without an address.

$261set ip dsl vccn rip-send { off | v1 | v2 | v1-compat | v2-MD5 }Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-casts to advertise its routing tables to other routers. RIP Version 2 (RIP-2) is an extension of the original Routing Information Protocol (RIP-1) that expands the amount of useful information in the RIP packets. While RIP-1 and RIP-2 share the same basic algorithms, RIP-2 supports several additional features, includ-ing inclusion of subnet masks in RIP packets and implementation of multicasting instead of broadcasting (which reduces the load on hosts which do not support routing protocols. RIP-2 with MD5 authentication is an extension of RIP-2 that increases security by requiring an authentication key when routes are advertised.Depending on your network needs, you can conﬁgure your Motorola Netopia® Gateway to support RIP-1, RIP-2, or RIP-2MD5.If you specify v2-MD5, you must also specify a rip-send-key. Keys are ASCII strings with a maximum of 31 characters, and must match the other router(s) keys for proper operation of MD5 support.set ip dsl vccn rip-receive { off | v1 | v2 | v1-compat | v2-MD5 }Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-casts to update its routing tables with information received from other routers.If you specify v2-MD5, you must also specify a rip-receive-key. Keys are ASCII strings with a maximum of 31 characters, and must match the other router(s) keys for proper operation of MD5 support.Ethernet LAN Settingsset ip ethernet A option { on | off }Enables or disables communications through the designated Ethernet port in the Gateway. You must enable TCP/IP functions for an Ethernet port before you can conﬁgure its network settings.set ip ethernet A address ip_addressAssigns an IP address to the Motorola Netopia® Gateway on the local area network. The IP address you assign to the local Ethernet inter face must be unique on your network. By default, the Motorola Netopia® Gateway uses 192.168.1.254 as its LAN IP address.set ip ethernet A broadcast broadcast_addressSpeciﬁes the broadcast address for the local Ethernet interface. IP hosts use the broadcast address to send messages to every host on your network simultaneously. The broadcast address for most networks is the network number followed by 255. For example, the broad-cast address for the 192.168.1.0 network would be 192.168.1.255.$

Administrator’s Handbook262set ip ethernet A netmask netmaskSpeciﬁes the subnet mask for the local Ethernet inter face. The subnet mask speciﬁes which bits of the 32-bit binary IP address represent network information. The default subnet mask for most networks is 255.255.255.0 (Class C subnet mask).set ip ethernet A restrictions { none | admin-disabled }Speciﬁes whether an administrator can open a telnet connection to a Motorola Netopia® Gateway over an Ethernet inter face (A = the LAN) to monitor and conﬁgure the unit.The admin-disabled argument prevents access to the device via telnet, web, and SNMP.By default, administrative restrictions are none on the LAN, but admin-disabled is set on the WAN. This means that, by default, an administrator can open, for example, a telnet connection from the LAN, but not the WAN.set ip ethernet A rip-send { off | v1 | v2 | v1-compat | v2-MD5 }Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-casts to advertise its routing tables to other routers on your network. RIP Version 2 (RIP-2) is an extension of the original Routing Information Protocol (RIP-1) that expands the amount of useful information in the RIP packets. While RIP-1 and RIP-2 share the same basic algorithms, RIP-2 supports several additional fea-tures, including inclusion of subnet masks in RIP packets and implementation of multicasting instead of broadcasting (which reduces the load on hosts which do not support routing protocols. RIP-2 with MD5 authentication is an extension of RIP-2 that increases security by requiring an authentication key when routes are advertised.If you specify v2-MD5, you must also specify a rip-send-key. Keys are ASCII strings with a maximum of 31 characters, and must match the other router(s) keys for proper operation of MD5 support.Depending on your network needs, you can conﬁgure your Motorola Netopia® Gateway to support RIP-1, RIP-2, or RIP-2MD5.set ip ethernet A rip-receive { off | v1 | v2 | v1-compat | v2-MD5 }Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-casts to update its routing tables with information received from other routers on your network.If you specify v2-MD5, you must also specify a rip-receive-key. Keys are ASCII strings with a maximum of 31 characters, and must match the other router(s) keys for proper operation of MD5 support.Additional subnetsSee “DHCP Settings” on page 248 for subnet range conﬁguration commands.set ip ethernet A subnet [ 2 ... 8 ] option [ on | off ]Enables or disables additional LAN subnets. Up to seven additional subnets may be conﬁgured.

$263set ip ethernet A subnet n address ip_addressSpeciﬁes an IP address for the subnet n, when subnet n option is on.set ip ethernet A subnet n netmask netmaskSpeciﬁes the subnet mask for the subnet n, when subnet n option is on.Default IP Gateway Settingsset ip gateway option { on | off }Speciﬁes whether the Motorola Netopia® Gateway should send packets to a default Gateway if it does not know how to reach the destination host.set ip gateway interface { ip-address | ppp-vccn }Speciﬁes how the Motorola Netopia® Gateway should route information to the default Gateway. If you select ip-address, you must enter the IP address of a host on a local or remote network. If you specify ppp, the Motorola Netopia® unit uses the default gateway being used by the remote PPP peer.IP-over-PPP Settings. Use the following commands to conﬁgure settings for routing IP over a virtual PPP interface.☛ NOTE:For a DSL platform you must identify the virtual PPP interface [vccn], a number from 1 to 8. set ip ip-ppp [vccn] option { on | off }Enables or disables IP routing through the virtual PPP interface. By default, IP routing is turned on. If you turn off IP routing and save the new conﬁguration, the Motorola Netopia® Gateway clears IP routing set-tingsset ip ip-ppp [vccn] address ip_addressAssigns an IP address to the virtual PPP interface. If you specify an IP address other than 0.0.0.0, your Motorola Netopia® Gateway will not negotiate its IP address with the remote peer. If the remote peer does not accept the IP address speciﬁed in the ip_address argument as valid, the link will not come up.The default value for the ip_address argument is 0.0.0.0, which indicates that the virtual PPP interface will use the IP address assigned to it by the remote peer. Note that the remote peer must be conﬁgured to supply an IP address to your Motorola Netopia® Gateway if you enter 0.0.0.0 for the ip_address argu-ment.$

$Administrator’s Handbook264set ip ip-ppp [vccn] peer-address ip_addressSpeciﬁes the IP address of the peer on the other end of the PPP link. If you specify an IP address other than 0.0.0.0, your Motorola Netopia® Gateway will not negotiate the remote peer's IP address. If the remote peer does not accept the address in the ip_address argument as its IP address (typically because it has been conﬁgured with another IP address), the link will not come up.The default value for the ip_address argument is 0.0.0.0, which indicates that the virtual PPP interface will accept the IP address returned by the remote peer. If you enter 0.0.0.0, the peer system must be con-ﬁgured to supply this address.set ip ip-ppp [vccn] restrictions { admin-disabled | none }Speciﬁes restrictions on the types of trafﬁc the Motorola Netopia® Gateway accepts over the PPP virtual circuit. The admin-disabled argument means that access to the device via telnet, web, and SNMP is disabled. RIP and ICMP trafﬁc is still accepted. The none argument means that all trafﬁc is accepted.set ip ip-ppp [vccn] addr-mapping [ on | off ]Speciﬁes whether you want the Motorola Netopia® Gateway to use network address translation (NAT) when communicating with remote routers. Address mapping lets you conceal details of your network from remote routers. It also permits all LAN devices to share a single IP address. By default, address mapping is turned “On”.set ip ip-ppp [vccn] auto-sensing [ off | dhcp/pppoe | pppoe/pppoa ]Enables or disables DHCP/PPPoE or PPPoE/PPPoA autosensing on the speciﬁed interface. Setting this to DHCP/PPPoE enables automatic sensing of your WAN connection type: PPPoE or DHCP. The gateway attempts to connect using PPPoE ﬁrst. If the Gateway fails to connect after 60 seconds, it switches to DHCP. As soon as it can connect via DHCP, the Gateway chooses and sets DHCP as its default. Otherwise, after attempting to connect via DHCP for 60 seconds, the Gateway switches back to PPPoE. The Gateway will continue to switch back and forth in this manner until it successfully connects. Similarly, selecting PPPoE/PPPoA causes the Gateway to attempt to connect by trying these protocols in parallel, and using the ﬁrst one that is successful.set ip ip-ppp [vccn] rip-send { off | v1 | v2 | v1-compat | v2-MD5 }Speciﬁes whether the Motorola Netopia® Gateway unit should use Routing Information Protocol (RIP) broad-casts to advertise its routing tables to routers on the other side of the PPP link. An extension of the original Routing Information Protocol (RIP-1), RIP Version 2 (RIP-2) expands the amount of useful information in the packets. While RIP-1 and RIP-2 share the same basic algorithms, RIP-2 supports several new features. For example, inclusion of subnet masks in RIP packets and implementation of multicasting instead of broad-casting. This last feature reduces the load on hosts which do not support routing protocols. RIP-2 with MD5 authentication is an extension of RIP-2 that increases security by requiring an authentication key when routes are advertised.This command is only available when address mapping for the speciﬁed virtual circuit is turned “off”.If you specify v2-MD5, you must also specify a rip-send-key. Keys are ASCII strings with a maximum of 31 characters, and must match the other router(s) keys for proper operation of MD5 support.$

265set ip ip-ppp [vccn] rip-receive { off | v1 | v2 | v1-compat | v2-MD5 }Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-casts to update its routing tables with information received from other routers on the other side of the PPP link.If you specify v2-MD5, you must also specify a rip-receive-key. Keys are ASCII strings with a maximum of 31 characters, and must match the other router(s) keys for proper operation of MD5 support.set ip ip-ppp vccn igmp-null-source-addr [ on | off ]Speciﬁes whether you want the Motorola Netopia® Gateway to identify the source IP address of every IGMP packet transmitted from this interface as 0.0.0.0 when mcast-fwd is set to on. This complies with the requirements of TR-101, and removes the need for a publicly advertised IP address on the WAN interface.set ip ip-ppp vccn mcast-fwd [ on | off ]Speciﬁes whether you want the Motorola Netopia® Gateway interface to act as an IGMP proxy host.set ip ip-ppp vccn unnumbered [ on | off ]Speciﬁes whether you want the Motorola Netopia® Gateway to have its WAN interface unnumbered, i.e. set to 0. set ip ip-ppp vccn dns acquired-dns-priority [ 0 - 255 ]Sets the priority for DNS acquired via PPP. See “Domain Name System Settings” on page 255 for more information.

Administrator’s Handbook266Static ARP SettingsYour Motorola Netopia® Gateway maintains a dynamic Address Resolution Protocol (ARP) table to map IP addresses to Ethernet (MAC) addresses. Your Motorola Netopia® Gateway populates this ARP table dynam-ically, by retrieving IP address/MAC address pairs only when it needs them. Optionally, you can deﬁne static ARP entries to map IP addresses to their corresponding Ethernet MAC addresses. Unlike dynamic ARP table entries, static ARP table entries do not time out.You can conﬁgure as many as 16 static ARP table entries for a Motorola Netopia® Gateway. Use the follow-ing commands to add static ARP entries to the Motorola Netopia® Gateway static ARP table:set ip static-arp ip-address ip_addressSpeciﬁes the IP address for the static ARP entry. Enter an IP address in the ip_address argument in dot-ted decimal format. The ip_address argument cannot be 0.0.0.0.set ip static-arp ip-address ip_address hardware-address MAC_addressSpeciﬁes the Ethernet hardware address for the static ARP entry. Enter an Ethernet hardware address in the MAC_address argument in nn.nn.nn.nn.nn.nn (hexadecimal) format.IGMP Forwardingset ip igmp-forwarding [ off | on ]Turns IP IGMP forwarding off or on. The default is off.IPsec Passthroughset ip ipsec-passthrough [ off | on ]Turns IPsec client passthrough off or on. The default is on.IP Prioritizationset ip prioritize [ off | on ]Allows you to support trafﬁc that has the TOS bit set. This defaults to off.

267Differentiated Services (DiffServ)set diffserv option [ off | on ]Turns the DiffServ option off (default) or on. on enables the service and IP TOS bits are used, even if no ﬂows are deﬁned. Consequently, if the end-point nodes provide TOS settings from an application that can be interpreted as one of the supported states, the Gateway will handle it as if it actively marked the TOS ﬁeld itself.☛ NOTE:The Gateway itself will not override TOS bit settings made by the endpoints. Support for source-provided IP TOS priorities within the Gateway is achieved simply by turning the Diff-Serve option “on” and by setting the lohi-asymmetry to adjust the behavior of the Gateway’s internal queues.set diffserv lohi-ratio [ 60 - 100 percent ]Sets a percentage between 60 and 100 used to regulate the level of packets allowed to be pending in the low priority queue. The default is 92. It can be used in some degree to adjust the relative throughput band-width for low- versus high-priority trafﬁc.☛ NOTE:diffserv lohi-ratio has been removed for VDSL, ADSL bonded units.

Choose the protocol number from this ﬁeld.•direction – Allows you to choose whether to apply the marking and gateway queue behavior for inbound packets, outbound packets, or to both. If the Gateway is used as an “edge” gateway, its more important function is to mark the packets for high-priority streams in the outbound direction.•start-port/end-port – Allows you to specify a range of ports to check for a particular ﬂow, if the protocol selection is TCP or UDP.•inside-ip/mask – If you want packets originating from a certain LAN IP address to be marked, enter the IP address and subnet mask here. If you leave the address equal to zero, this check is ignored for out-bound packets. The check is always ignored for inbound packets. The DiffServe queuing function must be applied ahead of NAT; and, before NAT re-maps the inbound packets, all inbound packets are des-tined for the Gateway's WAN IP address.•outside-ip/mask – If you want packets destined for and originating from a certain WAN IP address to be marked, enter this address and subnet mask here. If you leave the address equal to zero, the outside address check is ignored. For outbound ﬂows, the outside address is the destination IP address for the packets. For inbound packets, the outside address is the source IP address for the packets.Note: When setting the Inside/Outside IP Address/Netmask settings, note that a netmask value can be used to conﬁgure for a network rather than a single IP address.•qos – Allows you to specify the Quality of Service for the ﬂow: off, assure, expedite or network-con-trol. These are used both to mark the IP TOS byte and to distribute packets into the queues as if they were marked by the source. QoS Setting TOS Bit Value BehaviorOff TOS=000 This custom ﬂow is disabled. You can activate it by selecting one of the two settings below. This setting allows you to pre-deﬁne ﬂows without actually activating them.Assure TOS=001 Use normal queuing and throughput rules, but do not drop pack-ets if possible. Appropriate for applications with no guaranteed delivery mechanism.Expedite TOS=101 Use minimum delay. Appropriate for VoIP and video applications.Network Control TOS=111 Use highest possible priority.

271Queue ConﬁgurationBeginning with Firmware Version 7.7.4, the queuing characteristics of all “N” and “-02” model Gateway’s WAN interface can now be conﬁgured for:•strict priority queuing (as currently)•weighted fair queuing•rate-limiting funnel☛ Note:The conﬁguration mechanism is designed to be ﬂexible enough to accommodate complex queuing requirements. Conﬁgurations not supported by the Gateway will be ﬂagged during con-ﬁguration veriﬁcation.You conﬁgure the WAN outbound queue as follows:•create and conﬁgure one or more queues, which can be a basic queue or a priority queue comprising a group of basic queues, a weighted fair queue comprising a group of basic queues, or a funnel compris-ing a group of basic queues;•assign a queue instance to the Ethernet WAN interface;•map packet attributes to a queue.The same queue name can be assigned to multiple interfaces which require identical queue conﬁguration, however currently the only interface available for queueing conﬁguration is ethernet 1.To help you conﬁgure queues, and to maintain compatibility with previous ﬁrmware releases, several queues are set up automatically on upgrade to Version 7.7, or upon a factory reset.

Administrator’s Handbook272set queue name queue_name option [ on | off ] type [ basic | wfq | priority | funnel ]Creates a queue named queue_name and assigns a type:•basic – Basic Queue•wfq – Weighted Fair Queue•priority – Priority Queue•funnel – Funnel QueueBasic Queueset queue name basic_queue_name option [ on | off ]set queue name basic_queue_name type basicSpeciﬁes the Basic Queue named basic_queue_name attributes. Basic queues have one input and one output. The basic queue is assigned an ID, with the following attribute: when the queue is full, discard.By default, the following Basic Queues are created:•basic_q0•basic_q1•basic_q2•basic_q3

The default is on.Session Initiation Protocol, is a signaling protocol for Internet conferencing, telephony, presence, events notiﬁcation and instant messaging.RTSP Passthroughset ip ethernet B rtsp-passthrough [ off | on ]Turns Real Time Streaming Protocol application layer gateway client passthrough on or off. RTSP is a proto-col used for streaming media. It allows a client remotely to control a streaming media server. A typical application is Video-on-Demand (VoD). The default is on.Static Route SettingsA static route identiﬁes a manually conﬁgured pathway to a remote network. Unlike dynamic routes, which are acquired and conﬁrmed periodically from other routers, static routes do not time out. Consequently, static routes are useful when working with PPP, since an intermittent PPP link may make maintenance of dynamic routes problematic.You can conﬁgure as many as 32 static IP routes for a Motorola Netopia® Gateway. Use the following com-mands to maintain static routes to the Motorola Netopia® Gateway routing table:set ip static-routes destination-network net_addressSpeciﬁes the network address for the static route. Enter a network address in the net_address argu-ment in dotted decimal format. The net_address argument cannot be 0.0.0.0.set ip static-routes destination-network net_address netmask netmaskSpeciﬁes the subnet mask for the IP network at the other end of the static route. Enter the netmask argu-ment in dotted decimal format. The subnet mask associated with the destination network must represent the same network class (A, B, or C) or a lower class (such as a class C subnet mask for class B network number) to be valid.

$277set ip static-routes destination-network net_address interface { ip-address | ppp-vccn }Speciﬁes the interface through which the static route is accessible.set ip static-routes destination-network net_address gateway-address gate_addressSpeciﬁes the IP address of the Gateway for the static route. The default Gateway must be located on a net-work connected to the Motorola Netopia® Gateway conﬁgured interface.set ip static-routes destination-network net_address metric integerSpeciﬁes the metric (hop count) for the static route. The default metric is 1. Enter a number from 1 to 15 for the integer argument to indicate the number of routers (actual or best guess) a packet must traverse to reach the remote network.You can enter a metric of 1 to indicate either:•The remote network is one router away and the static route is the best way to reach it;•The remote network is more than one router away but the static route should not be replaced by a dynamic route, even if the dynamic route is more efﬁcient. set ip static-routes destination-network net_address rip-advertise [ splitHorizon | always | never ]Speciﬁes whether the gateway should use Routing Information Protocol (RIP) broadcasts to advertise to other routers on your network and which mode to use. The default is splitHorizon.delete ip static-routes destination-network net_addressDeletes a static route. Deleting a static route removes all information associated with that route.IPMaps Settingsset ip-maps name <name> internal-ip <ip address>Speciﬁes the name and static ip address of the LAN device to be mapped.set ip-maps name <name> external-ip <ip address>Speciﬁes the name and static ip address of the WAN device to be mapped.Up to 8 mapped static IP addresses are supported.$

Administrator’s Handbook278Network Address Translation (NAT) Default SettingsNAT default settings let you specify whether you want your Motorola Netopia® Gateway to forward NAT traf-ﬁc to a default server when it doesn’t know what else to do with it. The NAT default host function is useful in situations where you cannot create a speciﬁc NAT pinhole for a trafﬁc stream because you cannot antici-pate what port number an application might use. For example, some network games select arbitrary port numbers when a connection is being opened. By identifying your computer (or another host on your network) as a NAT default server, you can specify that NAT trafﬁc that would otherwise be discarded by the Motorola Netopia® Gateway should be directed to a speciﬁc hosts.set nat-default mode [ off | default-server | ip-passthrough ]Speciﬁes whether you want your Motorola Netopia® Gateway to forward unsolicited trafﬁc from the WAN to a default server or an IP passthrough host when it doesn’t know what else to do with it. See “Default Server” on page 89 for more information.set nat-default dhcp-enable [ on | off ]Allows the IP passthrough host to acquire its IP address via DHCP, if ip-passthrough is enabled. set nat-default address ip_addressSpeciﬁes the IP address of the NAT default server.set nat-default host-hardware-address MAC_address }Speciﬁes the hardware (MAC) address of the IP passthrough host. If the MAC address is speciﬁed as all-zeroes, the ﬁrst DHCP client that requests an IP address gets the passthrough address.Network Address Translation (NAT) Pinhole SettingsNAT pinholes let you pass speciﬁc types of network trafﬁc through the NAT interfaces on the Motorola Neto-pia® Gateway. NAT pinholes allow you to route selected types of network trafﬁc, such as FTP requests or HTTP (Web) connections, to a speciﬁc host behind the Motorola Netopia® Gateway transparently.To set up NAT pinholes, you identify the type(s) of trafﬁc you want to redirect by port number, and you spec-ify the internal host to which each speciﬁed type of trafﬁc should be directed.The following list identiﬁes protocol type and port number for common TCP/IP protocols:•FTP (TCP 21)•telnet (TCP 23)•SMTP (TCP 25),•TFTP (UDP 69)•SNMP (TCP 161, UDP 161) set pinhole name nameSpeciﬁes the identiﬁer for the entry in the router's pinhole table. You can name pinhole table entries sequentially (1, 2, 3), by port number (21, 80, 23), by protocol, or by some other naming scheme.

279set pinhole name name protocol-select { tcp | udp }Speciﬁes the type of protocol being redirected.set pinhole name name external-port-start [ 0 - 49151 ]Speciﬁes the ﬁrst port number in the range being translated.set pinhole name name external-port-end [ 0 - 49151 ]Speciﬁes the last port number in the range being translated.set pinhole name name internal-ip internal-ipSpeciﬁes the IP address of the internal host to which trafﬁc of the speciﬁed type should be transferred.set pinhole name name internal-port [ 0 - 65535 ]Speciﬁes the port number your Motorola Netopia® Gateway should use when forwarding trafﬁc of the spec-iﬁed type. Under most circumstances, you would use the same number for the external and internal port.PPPoE /PPPoA SettingsYou can use the following commands to conﬁgure basic settings, port authentication settings, and peer authentication settings for PPP interfaces on your Motorola Netopia® Gateway.Conﬁguring Basic PPP Settings. ☛ NOTE:For the DSL platform you must identify the virtual PPP interface [vccn], a number from 1 to 8.set ppp module [vccn] option { on | off }Enables or disables PPP on the Motorola Netopia® Gateway.set ppp module [vccn] auto-connect { on | off }Supports manual mode required for some vendors. The default on is not normally changed. If auto-connect is disabled (off), you must manually start/stop a ppp connection.set ppp module [vccn] mru integerSpeciﬁes the Maximum Receive Unit (MRU) for the PPP interface. The integer argument can be any num-ber between 128 and 1492 for PPPoE; 1500 otherwise.

Administrator’s Handbook280set ppp module [vccn] magic-number { on | off }Enables or disables LCP magic number negotiation.set ppp module [vccn] protocol-compression { on | off }Speciﬁes whether you want the Motorola Netopia® Gateway to compress the PPP Protocol ﬁeld when it transmits datagrams over the PPP link.set ppp module [vccn] lcp-echo-requests { on | off }Speciﬁes whether you want your Motorola Netopia® Gateway to send LCP echo requests. You should turn off LCP echoing if you do not want the Motorola Netopia® Gateway to drop a PPP link to a nonresponsive peer.set ppp module [vccn] echo-period integerSpeciﬁes the number of seconds the Motorola Netopia® Gateway should wait before sending another echo from an LCP echo request. The integer argument can be any number from between 5 and 300 (seconds).set ppp module [vccn] lost-echoes-max integerSpeciﬁes the maximum number of lost echoes the Motorola Netopia® Gateway should tolerate before bringing down the PPP connection. The integer argument can be any number from between 1 and 20.set ppp module [vccn] failures-max integerSpeciﬁes the maximum number of Conﬁgure-NAK messages the PPP module can send without having sent a Conﬁgure-ACK message. The integer argument can be any number between 1 and 20.set ppp module [vccn] conﬁgure-max integerSpeciﬁes the maximum number of unacknowledged conﬁguration requests that your Motorola Netopia® Gateway will send. The integer argument can be any number between 1 and 20.set ppp module [vccn] terminate-max integerSpeciﬁes the maximum number of unacknowledged termination requests that your Motorola Netopia® Gateway will send before terminating the PPP link. The integer argument can be any number between 1 and 10. set ppp module [vccn] restart-timer integerSpeciﬁes the number of seconds the Motorola Netopia® Gateway should wait before retransmitting a con-ﬁguration or termination request. The integer argument can be any number between 1 and 30.

281set ppp module [vccn] connection-type { instant-on | always-on }Speciﬁes whether a PPP connection is maintained by the Motorola Netopia® Gateway when it is unused for extended periods. If you specify always-on, the Motorola Netopia® Gateway never shuts down the PPP link. If you specify instant-on, the Motorola Netopia® Gateway shuts down the PPP link after the number of seconds speciﬁed in the time-out setting (below) if no trafﬁc is moving over the circuit.set ppp module [vccn] time-out integerIf you speciﬁed a connection type of instant-on, speciﬁes the number of seconds, in the range 30 - 3600, with a default value of 300, the Motorola Netopia® Gateway should wait for communication activity before terminating the PPP link.Conﬁguring Port Authentication. You can use the following command to specify how your Motorola Neto-pia® Gateway should respond when it receives an authentication request from a remote peer.The settings for port authentication on the local Motorola Netopia® Gateway must match the authentica-tion that is expected by the remote peer. For example, if the remote peer requires CHAP authentication and has a name and CHAP secret for the Motorola Netopia® Gateway, you must enable CHAP and specify the same name and secret on the Motorola Netopia® Gateway before the link can be established.set ppp module [vccn] port-authentication option [ off | on | pap-only | chap-only ]Specifying on turns both PAP and CHAP on, or you can select PAP or CHAP. Specify the username and password when port authentication is turned on (both CHAP and PAP, CHAP or PAP.) Authentication must be enabled before you can enter other information.set ppp module [vccn] port-authentication username usernameThe username argument is 1 – 255 alphanumeric characters. The information you enter must match the username conﬁgured in the PPP peer's authentication database. set ppp module [vccn] port-authentication password passwordThe password argument is 1 – 128 alphanumeric characters. The information you enter must match the password used by the PPP peer.

If set to on, this interface acts as an IGMP proxy host, and IGMP packets are transmitted and received on this interface on behalf of IGMP hosts on the LAN interface. See “IGMP (Internet Group Management Protocol)” on page 100 for more informa-tion.set ip ip-ppp vcc1 igmp-null-source-addr [ off | on ]Enables or disables IGMP null source address, if mcast-fwd is set to on. If enabled, the source IP address of every IGMP packet transmitted from this interface is set to 0.0.0.0. This complies with the requirements of TR-101, and removes the need for a publicly advertised IP address on the WAN interface.Ethernet Port Settingsset ethernet ethernet A mode { auto | 100M-full | 100M-full-ﬁxed | 100M-half-ﬁxed | 10M-full-ﬁxed | 10M-half-ﬁxed | 100M-half | 10M-full | 10M-half }Allows mode setting for the ethernet port. Only supported on units without a LAN switch, or dual ethernet products (338x). In the dual ethernet case, “ethernet B” would be speciﬁed for the WAN port. The default is auto.

Administrator’s Handbook284802.3ah Ethernet OAM Settings802.3ah Ethernet in the First Mile (EFM) Operations Administration and Maintenance (OAM) is a group of network management functions that provide network fault indication, performance information, and diagno-sis using special-purpose Ethernet OAM frames. These are exchanged between your Gateway and service provider Access Node (AN) devices for network fault management, performance analysis and fault isolation.All VDSL and Ethernet WAN Motorola Netopia Gateways support Ethernet OAM options.More Ethernet Packet-Transfer-Mode (PTM) enabled xDSL Motorola Netopia Gateways will support 802.3ah Ethernet OAM options in future releases.802.3ah Ethernet OAM exchanges periodic Ethernet OAM heartbeat frames between the endpoints of the physical link being monitored, and thus discovers and keeps-alive the Link connectivity and reports faults if the link goes down. Supported OAM request and response types are: remote loopback enable, remote loop-back disable, variable request, variable response.set ethernet oam ah option [ off | on ]Enables or disables Ethernet OAM. Default is off.set ethernet oam ah pass-through [ off | on ]Enable or disable Ethernet OAM pass-through mode. Default is off. Warning: This is a DEBUG feature. Leave it off unless you know exactly what you are doing.set ethernet oam ah mode [ active | passive ]Speciﬁes the Ethernet OAM mode. Default is active.set ethernet oam ah pdu-size-max [ 64 - 1518 ]Speciﬁes the Maximum Protocol Data Unit (PDU) size. Default is 1518.set ethernet oam ah discovery-timer [ 1 - 300 ]Speciﬁes the discovery timer value for continuity check in seconds. Range is 1 – 300 seconds. Default is 1.set ethernet oam ah keepalive-timer [ 5 - 305 ]Speciﬁes the keep-alive timer value in seconds. Range is 5 – 305 seconds. Default is 5.etheroam ah pingSends OAM remote loopback request in active mode.

285Command Line Interface Preference SettingsYou can set command line interface preferences to customize your environment. set preference verbose { on | off }Speciﬁes whether you want command help and prompting information displayed. By default, the command line interface verbose preference is turned off. If you turn it on, the command line interface displays help for a node when you navigate to that node.set preference more linesSpeciﬁes how many lines of information you want the command line interface to display at one time. The lines argument speciﬁes the number of lines you want to see at one time. The range is 1-65535. By default, the command line interface shows you 22 lines of text before displaying the prompt: More …[y|n] ?.If you enter 1000 for the lines argument, the command line interface displays information as an uninter-rupted stream (which is useful for capturing information to a text ﬁle).

Administrator’s Handbook286Port Renumbering SettingsIf you use NAT pinholes to forward HTTP or telnet trafﬁc through your Motorola Netopia® Gateway to an internal host, you must change the port numbers the Motorola Netopia® Gateway uses for its own conﬁgu-ration trafﬁc. For example, if you set up a NAT pinhole to forward network trafﬁc on Port 80 (HTTP) to another host, you would have to tell the Motorola Netopia® Gateway to listen for conﬁguration connection requests on a port number other than 80, such as 6080.After you have changed the port numbers the Motorola Netopia® Gateway uses for its conﬁguration trafﬁc, you must use those port numbers instead of the standard numbers when conﬁguring the Motorola Neto-pia® Gateway. For example, if you move the router's Web service to port “6080” on a box with a system (DNS) name of “superbox”, you would enter the URL http://superbox:6080 in a Web browser to open the Motorola Netopia® Gateway graphical user interface. Similarly, you would have to conﬁgure your telnet application to use the appropriate port when opening a conﬁguration connection to your Motorola Netopia® Gateway.set servers web-http [ 1 - 65534 ]Speciﬁes the port number for HTTP (web) communication with the Motorola Netopia® Gateway. Because port numbers in the range 0-1024 are used by other protocols, you should use numbers in the range 1025-65534 when assigning new port numbers to the Motorola Netopia® Gateway web conﬁguration interface. A setting of 0 (zero) will turn the server off.set servers telnet-tcp [ 1 - 65534 ]Speciﬁes the port number for telnet (CLI) communication with the Motorola Netopia® Gateway. Because port numbers in the range 0-1024 are used by other protocols, you should use numbers in the range 1025-65534 when assigning new port numbers to the Motorola Netopia® Gateway telnet conﬁguration interface. A setting of 0 (zero) will turn the server off.☛ NOTE:You cannot specify a port setting of 0 (zero) for both the web and telnet ports at the same time. This would prevent you from accessing the Gateway.

287Security SettingsSecurity settings include the Firewall, Packet Filtering, Stateful Inspection, and IPSec parameters. Some of the security functionality is keyed.Firewall Settings (for BreakWater Firewall)set security ﬁrewall option [ ClearSailing | SilentRunning | LANdLocked ]The 3 settings for BreakWater are discussed in detail on page page 142.SafeHarbour IPSec SettingsSafeHarbour VPN is a tunnel between the local network and another geographically dispersed network that is interconnected over the Internet. This VPN tunnel provides a secure, cost-effective alternative to dedi-cated leased lines. Internet Protocol Security (IPsec) is a series of services including encryption, authenti-cation, integrity, and replay protection. Internet Key Exchange (IKE) is the key management protocol of IPsec that establishes keys for encryption and decryption. Because this VPN software implementation is built to these standards, the other side of the tunnel can be either another Motorola Netopia® unit or another IPsec/IKE based security product. For VPN you can choose to have trafﬁc authenticated, encrypted, or both.When connecting the Motorola Netopia® unit in a telecommuting scenario, the corporate VPN settings will dictate the settings to be used in the Motorola Netopia® unit. If a parameter has not been speciﬁed from the other end of the tunnel, choose the default unless you fully understand the ramiﬁcations of your param-eter choice.set security ipsec option (off) {on | off}Turns on the SafeHarbour IPsec tunnel capability. Default is off.

For example, after 82800 seconds (23 hours) or 1 Gbyte has been transferred (whichever comes ﬁrst) the key will begin to be renegotiated.•The hard parameters indicate that the renegotiation must be complete or the tunnel will be disabled. For example, 86400 seconds (24 hours) means that the renegotiation must be complete within one day. Both ends of the tunnel set parameters, and typically they will be the same. If they are not the same, the rekey event will happen when the longest time period expires or when the largest amount of data has been sent.

297SNMP SettingsThe Simple Network Management Protocol (SNMP) lets a network administrator monitor problems on a net-work by retrieving settings on remote network devices. The network administrator typically runs an SNMP management station program on a local host to obtain information from an SNMP agent such as the Motor-ola Netopia® Gateway.set snmp community read nameAdds the speciﬁed name to the list of communities associated with the Motorola Netopia® Gateway. By default, the Motorola Netopia® Gateway is associated with the public community.set snmp community write nameAdds the speciﬁed name to the list of communities associated with the Motorola Netopia® Gateway.set snmp community trap nameAdds the speciﬁed name to the list of communities associated with the Motorola Netopia® Gateway.set snmp trap ip-traps ip-addressIdentiﬁes the destination for SNMP trap messages. The ip-address argument is the IP address of the host acting as an SNMP console.set snmp sysgroup contact contact_infoIdentiﬁes the system contact, such as the name, phone number, beeper number, or email address of the person responsible for the Motorola Netopia® Gateway. You can enter up to 255 characters for the contact_info argument. You must put the contact_info argument in double-quotes if it contains embedded spaces.set snmp sysgroup location location_infoIdentiﬁes the location, such as the building, ﬂoor, or room number, of the Motorola Netopia® Gateway. You can enter up to 255 characters for the location_info argument. You must put the location_info argument in double-quotes if it contains embedded spaces.SNMP Notify Type Settingsset snmp notify type [ v1-trap | v2-trap | inform ]Sets the type of SNMP notiﬁcations that the system will generate: •v1-trap – This selection will generate notiﬁcations containing an SNMPv1 Trap Protocol Data Unit (PDU)•v2-trap – This selection will generate notiﬁcations containing an SNMPv2 Trap PDU•inform – This selection will generate notiﬁcations containing an SNMPv2 InformRequest PDU.

Administrator’s Handbook298System SettingsYou can conﬁgure system settings to assign a name to your Motorola Netopia® Gateway and to specify what types of messages you want the diagnostic log to record.set system name nameSpeciﬁes the name of your Motorola Netopia® Gateway. Each Motorola Netopia® Gateway is assigned a name as part of its factory initialization. The default name for a Motorola Netopia® Gateway consists of the word “Netopia-3000/XXX” where “XXX” is the serial number of the device; for example, Netopia-3000/9437188. A system name can be 1 – 255 characters long. Once you have assigned a name to your Motor-ola Netopia® Gateway, you can enter that name in the Address text ﬁeld of your browser to open a connec-tion to your Motorola Netopia® Gateway.☛ NOTE:Some broadband cable-oriented Service Providers use the System Name as an important identiﬁcation and support parameter. If your Gateway is part of this type of network, do NOT alter the System Name unless speciﬁcally instructed by your Service Provider.set system diagnostic-level { off | low | medium | high | alerts | failures }Speciﬁes the types of log messages you want the Motorola Netopia® Gateway to record. All messages with a level equal to or greater than the level you specify are recorded. For example, if you specify set system diagnostic-level medium, the diagnostic log will retain medium-level informational messages, alerts, and failure messages. Specifying off turns off logging.Use the following guidelines:•low - Low-level informational messages or greater; includes trivial status messages.•medium - Medium-level informational messages or greater; includes status messages that can help monitor network trafﬁc.•high - High-level informational messages or greater; includes status messages that may be signiﬁcant but do not constitute errors. The default.•alerts - Warnings or greater; includes recoverable error conditions and useful operator information.•failures - Failures; includes messages describing error conditions that may not be recoverable.

299set system ftp-server option [ off | on ]Enables or disables a simple FTP server in the Gateway. If enabled, the Gateway will accept binary embed-ded software images (‘.bin’) ﬁles or command line conﬁguration ﬁles.set system log-size [ 10240... 65536 ]Speciﬁes a size for the system log. The most recent entries are posted to the beginning of the log. When the log becomes full, the oldest entries are dropped. The default is 30000.set system persistent-log [ off | on ]When set to on, causes the log information to be kept in ﬂash memory.set system idle-timeout { telnet [ 1...120 ] | http [ 1... 120 ] }Speciﬁes a timeout period of inactivity for telnet or HTTP access to the Gateway, after which a user must re-login to the Gateway. Defaults are 5 minutes for HTTP and 15 minutes for telnet.set system username { administrator name | user name }Speciﬁes the usernames for the administrative user – the default is admin; and a non-administrative user – the default is user.set system password { admin | user }Speciﬁes the administrator or user password for a Motorola Netopia® Gateway. When you enter the set system password command, you are prompted to enter the old password (if any) and new password. You are prompted to repeat the new password to verify that you entered it correctly the ﬁrst time. To prevent anyone from observing the password you enter, characters in the old and new passwords are not displayed as you type them. For security, you cannot use the “step” method to set the system password.A password can be as many as 8 characters. Passwords are case-sensitive. Passwords go into effect immediately. You do not have to restart the Motorola Netopia® Gateway for the password to take effect. Assigning an administrator or user password to a Motorola Netopia® Gateway does not affect communications through the device. Supported FTP commandsMODE (data transfer mode (only Streaming supported)NOOP (send back ok)PORT (specify client address:port for data)QUIT (quit)STOR (send ﬁle to FTP server)SYST (get system info about FTP server)TYPE (set data representation type, ASCII and IMAGE (BIN) only supported)USER (send username for authentication)

You can specify the protocol, port, IP-, port-, and URL-server. •The interval setting speciﬁes the broadcast update frequency. Part of sequence control. The interval is the spacing between heartbeats, in d:h:m:s.•The contact-email setting is a quote-enclosed text string giving an email address for the Gateway’s administrator. •The location setting is a text string allowing you to specify your geographical or other location, such as “Secaucus, NJ.”• The number setting is part of the sequence control. This is the number of heartbeats to send, at each “interval”, before sleeping. For example, if this is 20, in the above layout, each heartbeat sequence will send out a total 20 heartbeats, spaced at 30 second intervals, and then sleep for 30 minutes. So to have the Gateway send out packets “forever”, this number can be set very high. If it is 1440 and the interval is 1 minute, say, the heartbeat will go out every minute for 1440 minutes, or one day, before sleeping.•The sleep setting is part of sequence control. This is the time to sleep before starting another heart-beat sequence, in d:h:m:s.set system ntp option [ off | on ]:server-address (north-america.pool.ntp.org)alt-server-address (pool.ntp.org):time-zone [ -12 - 12 ] update-period (60) [ 1 - 65535 ]: daylight-savings [ off | on ]Speciﬁes the NTP server address, time zone, and how often the Gateway should check the time from the NTP server. The NTP server-address and alt-server-address can be entered as DNS names as well as IP addresses. NTP time-zone of 0 is GMT time; options are -12 through 12 (+/- 1 hour increments from GMT time). update-period speciﬁes how often, in minutes, the Gateway should update the clock. daylight-sav-ings speciﬁes whether daylight savings time is in effect; it defaults to off.set system zerotouch option [ on | off ]Enables or disables the Zero Touch option.$

301Zero Touch refers to automatic conﬁguration of your Motorola Netopia® Gateway. The Motorola Netopia® Gateway has default settings such that initial connection to the Internet will succeed.

$303Wireless Settings (supported models)set wireless option ( on | off )Administratively enables or disables the wireless interface.set wireless network-id ssid { network_name }Speciﬁes the wireless network id for the Gateway. A unique ssid is generated for each Gateway. You must set your wireless clients to connect to this exact id, which can be changed to any 32-character string.set wireless auto-channel mode { off | at-startup | continuous }Speciﬁes the wireless AutoChannel Setting for 802.11G models. AutoChannel is a feature that allows the Motorola Netopia® Gateway to determine the best channel to broadcast automatically. For details, see “Advanced” on page 56.set wireless default-channel { 1...14 }Speciﬁes the wireless 2.4GHz sub channel on which the wireless Gateway will operate. For US operation, this is limited to channels 1–11. Other countries vary; for example, Japan is channel 14 only. The default channel in the US is 6. Channel selection can have a signiﬁcant impact on performance, depending on other wireless activity in proximity to this AP. Channel selection is not necessary at the clients; clients will scan the available channels and look for APs using the same ssid as the client.set wireless network-id closed-system { on | off }When this setting is enabled, a client must know the ssid in order to connect or even see the wireless access point. When disabled, a client may scan for available wireless access points and will see this one. Enable this setting for greater security. The default is on.set wireless mode { both-b-and-g | b-only | g-only }Speciﬁes the wireless operating mode for connecting wireless clients: both-b-and-g, b-only, or g-only, and locks the Gateway in that mode.☛ NOTE:If you choose to limit the operating mode to B or G only, clients using the mode you excluded will not be able to connect.set wireless multi-ssid option { on | off }Enables or disables the multi-ssid feature which allows you to add additional network identiﬁers (SSIDs or Network Names) for your wireless network. When enabled, you can specify up to three additional SSIDs with separate privacy settings for each. See below.$

For 40/64bit encryption, you need 10 digits; 26 digits for 128bit, and 58 digits for 256bit WEP. Valid hexa-decimal characters are 0 – 9, a – f. set wireless no-bridging [ off | on ]When set to on, this will block wireless clients from communicating with other wireless clients on the LAN side of the Gateway.set wireless tx-power [ full | medium | fair | low | minimal ]Sets the wireless transmit power, scaling down the router's wireless transmit coverage by lowering its radio power output. Default is full power. Transmit power settings are useful in large venues with multiple wire-less routers where you want to reuse channels. Since there are only three non-overlapping channels in the 802.11 spectrum, it helps to size the Gateway’s cell to match the location. This allows you to install a router to cover a small “hole” without conﬂicting with other routers nearby.

Administrator’s Handbook308Wireless Privacy Settingsset wireless network-id privacy option { off | WEP | WPA-PSK | WPA-802.1x }Speciﬁes the type of privacy enabled on the wireless LAN. off = no privacy; WEP = WEP encryption; WPA-PSK = Wireless Protected Access/Pre-Shared Key; WPA-802.1x = Wireless Protected Access/802.1x authentication. See “Wireless” on page 53 for a discussion of these options.WPA provides Wireless Protected Access, the most secure option for your wireless network. This mecha-nism provides the best data protection and access control. PSK requires a Pre-Shared Key; 802.1x requires a RADIUS server for authentication.WEP is Wired Equivalent Privacy, a method of encrypting data between the wireless Gateway and its clients. It is strongly recommended to turn this on as it is the primary way to protect your network and data from intruders. Note that 40bit is the same as 64bit and will work with either type of wireless client. The default is off.A single key is selected (see default-key) for encryption of outbound/transmitted packets. The WEP-enabled client must have the identical key, of the same length, in the identical slot (1..4) as the wireless Gateway, in order to successfully receive and decrypt the packet. Similarly, the client also has a ‘default’ key that it uses to encrypt its transmissions. In order for the wireless Gateway to receive the client’s data, it must likewise have the identical key, of the same length, in the same slot. For simplicity, a wireless Gate-way and its clients need only enter, share, and use the ﬁrst key.set wireless network-id privacy pre-shared-key stringThe Pre Shared Key is a passphrase shared between the Router and the clients and is used to generate dynamically changing keys, when WPA-PSK is selected or enabled. The passphrase can be 8 – 63 charac-ters. It is recommended to use at least 20 characters for best security.set wireless network-id privacy default-keyid { 1...4 }Speciﬁes which WEP encryption key (of 4) the wireless Gateway will use to transmit data. The client must have an identical matching key, in the same numeric slot, in order to successfully decode. Note that a client allows you to choose which of its keys it will use to transmit. Therefore, you must have an identical key in the same numeric slot on the Gateway.For simplicity, it is easiest to have both the Gateway and the client transmit with the same key.
