Initial Configuration4-144

5-1Chapter 5: System ConfigurationThe wireless AP/Router offers a user-friendly web-based management interface for the configuration of all the unit’s features. Any PC directly attached to the unit can access the management interface using a web browser, such as Internet Explorer (version 6.0 or above).This chapter describes the wireless AP/Router’s configurable features, all of which may be accessed through the web interface. Note: Before accessing the web interface, first set the device to Router or AP Mode using the switch on the bottom panel. Note that the unit reboots when the operating mode is changed.It is recommended to make initial configuration changes by connecting a PC directly to one of the wireless AP/Router's LAN ports. The wireless AP/Router has a default IP address of 192.168.2.1 and a subnet mask of 255.255.255.0. If your PC is set to "Obtain an IP address automatically" (that is, set as a DHCP client), you can connect immediately to the web interface. Otherwise, you must set your PC IP address to be on the same subnet as the wireless AP/Router (that is, the PC and wireless AP/Router addresses must both start 192.168.2.x).To access the configuration menu, follow these steps:1. Use your web browser to connect to the management interface using the default IP address of 192.168.2.1.2. Log into the wireless AP/Router management interface by entering the default username “admin” and password also “smcadmin,” then click Login.Note: It is strongly recommended to change the default user name and password the first time you access the web interface. For information on changing user names and passwords, See “Admin Accounts and Remote Administration” on page 5-60Figure 5-1. Login Page

Wireless Settings5-215Wireless SettingsThe IEEE 802.11n interfaces include configuration options for radio signal characteristics and wireless security features. The wireless AP/Router can operate in five modes, mixed 802.11b/g/n, mixed 802.11b/g, 802.11b only, 802.11g only or 802.11n only. Also note that 802.11g is backward compatible with 802.11b, and 802.11n is backward compatible with both 802.11b/g at slower data transmit rates.Each radio supports two virtual access point (VAP) interfaces, referred to as WLAN1 and WLAN2. Each VAP functions as a separate access point, and can be configured with its own Service Set Identification (SSID) and security settings. However, most radio signal parameters apply to both VAP interfaces. The configuration options are nearly identical, and are therefore both covered in this section of the manual.Traffic to specific VAPs can be segregated based on user groups or application traffic. Both VAPs can have up to 64 wireless clients, whereby the clients associate with these VAPs the same as they would with a physical access point.Note: The radio channel settings for the access point are limited by local regulations, which determine the number of channels that are available. See “Specifications” on page B-1“ for additional information on the maximum number channels available.The hardware switch feature to toggle between Router and AP Mode, located on the base of the wireless AP/Router, affects some of the Wireless Interface parameters. However, most radio signal parameters apply in both modes so will be described together in the following sections.Changing settings in the Wireless Settings configuration and clicking “submit" prompts you to either “Reboot” for your changes to immediately take effect, or “Continue” to continue making configuration changes without them taking effect until you next reboot.Figure 5-15. Changing Settings

System Configuration5-225Choosing to reboot after making configuration changes triggers a countdown window that requires 60 seconds to complete.Figure 5-16. Implementing Changed SettingsBasic SettingsThe Basic Setting page allows you to enable the wireless interface, select which radio mode to use, choose the transmit frequency and configure SSIDs. Click on "Wireless Settings," followed by "Basic Setting."Note: There are several variables to consider when selecting a radio mode that make it fully functional. Simply selecting the mode you want is not enough to ensure full compatibility for that mode. Information on these variables may be found in the Advanced Setting section.Figure 5-17. Basic Radio Settings•WLAN – Enables the communication for the VAP wireless interface. (Default: Enabled)•WLAN Mode – Defines the radio mode for the VAP interface.(Default: 802.11b/g/n Mixed)Note: Enabling the wireless AP/Router to communicate with 802.11b/g clients in both 802.11b/g/n Mixed and 802.11n modes also requires that HT Operation in the Advanced Settings menu be set to Mixed. Setting HT Operation to Green Field is exclusive for 802.11n client communication only and prevents 802.11 b/g communication.-802.11b/g/n Mixed: All 802.11b/g/n clients can communicate with the wireless AP/Router (up to 300 Mbps), but data transmission rates may be slowed to compensate for 802.11b/g clients.

(Default: Auto): -Auto: The wireless AP/Router enables its protection mechanism for 802.11b clients when they are detected in the network. When 802.11b clients are not detected, the protection mechanism is disabled.-Always On: Forces the unit to always use protection for 802.11b clients, whether they are detected in the network or not.-Always Off: Forces the unit to never use protection for 802.11b clients. This prevents 802.11b clients from connecting to the network.Note: Enabling “Always On” b/g Protection can slow throughput for 802.11g/n clients by as much as 50%. •HT Operation Mode – Packets from 802.11n clients are referred to as High Throughput (HT) Greenfield packets, in other words packets that can be transmitted at rates of up to 300 Mbps assuming that HT Channel Bandwidth is set to 20/40Mhz, see HT Channel Bandwidth next page. Note: Some 802.11n wireless clients may be capable of transmission rates of up to 600 Mbps, however the wireless AP/Router will only be able to connect to them at a maximum transmission rate of 300 Mbps.

Wireless Settings5-255802.11b/g packets are referred to as non-HT packets, being transmitted at lower throughput rates. HT mixed format frames contain a preamble compatible with the non-HT receivers.HT Greenfield frames do not contain a non-HT compatible part. Support for HT Greenfield format is optional. An HT station that does not support the reception of an HT Greenfield format frame must be able to detect that an HT Greenfield format frame is an HT transmission (as opposed to a non-HT transmission). In this case the receiver must decode the high throughput signal (HT-SIG) in the packet header and determine if the HT-SIG cyclic redundancy check (CRC) passes. (Default: Mixed)•HT Channel Bandwidth – The wireless AP/Router provides a channel bandwidth of 40 MHz by default giving an 802.11g connection speed of 108 Mbps (sometimes referred to as Turbo Mode) and a 802.11n connection speed of up to 300 Mbps. Setting the HT Channel Bandwidth to 20 MHz slows connection speed for 802.11g and 802.11n to 54 Mbps and 74 Mbps respectively and ensures backward compliance for slower 802.11b devices. (Default: 20/40Mhz)•HT TX Aggregate MSDU – This option enables Mac Service Data Unit (MSDU) aggregation. (Default: Enabled)WLAN1~WLAN2 — Stipulates settings specific to each VAP interface.•Hide SSID – Hiding the SSID of the VAP increases security of the network but does not allow clients to detect your presence on the network and requires that clients already know your SSID. (Default: Disabled)•WMM Support – Wi-Fi Multimedia (WMM), also known as Wireless Multimedia Extensions (WME), is a Wi-Fi Alliance interoperability certification. It provides basic Quality of Service (QoS) features for IEEE 802.11 wireless network. Enabling WMM support provides prioritization of Wi-Fi data packets on four categories voice, video, best effort, and background. (Default: Enabled)•Save – Saves and enables the Advanced Wireless Setting configuration.•Cancel – Restores the previous Advanced Wireless Setting configuration information.

System Configuration5-265WLAN SecurityThe wireless AP/Router’s wireless interface is configured by default as an “open system,” which broadcasts a beacon signal including the configured SSID. Wireless clients with a configured SSID of “ANY” can read the SSID from the beacon, and automatically set their SSID to allow immediate connection to the wireless network.To improve wireless network security, you have to implement two main functions:• Authentication – It must be verified that clients attempting to connect to the network are authorized users.• Traffic Encryption – Data passing between the unit and clients must be protected from interception and eavesdropping.For a more secure network, the wireless AP/Router can implement one or a combination of the following security mechanisms:• Wired Equivalent Privacy (WEP)• IEEE 802.1X• Wi-Fi Protected Access (WPA) or WPA2The security mechanisms that may be employed depend on the level of security required, the network and management resources available, and the software support provided on wireless clients.WLAN1 and WLAN2 SecurityThe wireless AP/Router supports two virtual access point (VAP) interfaces referred to as WLAN1 and WLAN2. Each VAP functions as a separate access point, and can be configured with its own security settings.Note: WDS settings may only be configured for WLAN1, See “WDS Settings” on page 5-33. WLAN2 only operates as an access point service.Note: Configuring WLAN1 to operate in Bridge mode automatically disables WLAN2.Click "Wireless Settings" followed by either "WLAN1 Security" or "WLAN2 Security."

Wireless Settings5-295Security Settings — The security settings determine the authentication mode and enable WEP keys. •Authentication Mode – Configures the authentication mode used by clients.(WLAN1/WLAN2 Defaults: Open)-Open: Open-system authentication accepts any client attempting to connect the wireless AP/Router without verifying its identity. In this mode the default encryption type is "None." -Shared: The shared-key approach uses Wired Equivalent Privacy (WEP) to verify client identity by distributing a shared key to clients before attempting authentication.-WEP Auto: Allows WLAN clients to associate using Open-WEP (uses WEP for encryption only) or Shared-WEP ( uses WEP for authentication and encryption). If enabled, you must configure at least one key for the VAP interface and all its clients. Wired Equivalent Privacy (WEP) provides a basic level of security, preventing unauthorized access to the network and encrypting data transmitted between wireless clients and the wireless AP/Router. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network.-WPA Personal or WPA2 Personal: The WPA or WPA2 Personal mode uses a common password phrase, called a Pre-Shared Key, that must be manually distributed to all clients that want to connect to the network. Specify a key as an easy-to-remember form of letters and numbers. The WPA Preshared Key can be input as ASCII string (8-63 characters) or Hexadecimal format (length is 64). All wireless clients must be configured with the same key to communicate with the VAP interface.

System Configuration5-305-WPA Enterprise or WPA2 Enterprise: The WPA Enterprise mode uses IEEE 802.1X as its basic framework for user authentication and dynamic key management. IEEE 802.1X access security uses Extensible Authentication Protocol (EAP) and requires a configured RADIUS authentication server to be accessible in the enterprise network. If you select WPA or WPA2 Enterprise mode, be sure to configure the RADIUS settings. See “RADIUS” on page 5-32 for more information. -WPA/WPA2 Personal: The WPA/WPA2 Personal Mode allows both WPA and WPA2 clients to join the network. The WPA Preshared Key can be input as ASCII string (8-63 characters) or Hexadecimal format (length is 64). All wireless clients must be configured with the same key to communicate with the VAP interface.-WPA/WPA2 Enterprise: Defines a transitional mode of operation for networks moving from WPA security to WPA2. WPA/WPA2 Enterprise Mode allows both WPA and WPA2 clients to associate to a common SSID interface. In WPA/WPA2 mixed mode, the unicast encryption cipher (TKIP or AES-CCMP) is negotiated for each client. The access point advertises its supported encryption ciphers in beacon frames and probe responses. WPA and WPA2 clients select the cipher they support and return the choice in the association request to the access point. For mixed-mode operation, the cipher used for broadcast frames is always TKIP. WEP encryption is not allowed.•Encryption Type – Selects the data encryption type to use. (Default: determined by the Authentication Mode selected)- None: Disables data encryption.- WEP: Selects WEP keys for data encryption.-TKIP: Uses Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA specifies TKIP as the data encryption method to replace WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys.-AES: Uses Advanced Encryption Standard (AES) keys for encryption. WPA2 uses AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-CCMP) provides extremely robust data confidentiality using a 128-bit key. Use of AES-CCMP encryption is specified as a standard requirement for WPA2. Before implementing WPA2 in the network, be sure client devices are upgraded to WPA2-compliant hardware.

Wireless Settings5-315-TKIP/AES: Uses either TKIP or AES keys for encryption. WPA/WPA2 mixed modes allow both WPA and WPA2 clients to associate to a common SSID interface. In mixed mode, the unicast encryption cipher (TKIP or AES-CCMP) is negotiated for each client.•Default Key ID – Sets the WEP key used for authentication. (Default: 1; Range: 1~4)•Key 1 ~ Key 4 – Sets WEP key values. The user must first choose between ASCII or Hexadecimal keys. At least one key must be specified. Each WEP key has an index number. The selected key is used for authentication and encryption on the VAP interface. Enter key values that match the key type and length settings. Standard keys are either 5 or 13 alphanumeric characters; or 10 or 26 hexadecimal digits. (Default: ASCII, no preset value) •WPA Group-Key ReKey Method – WPA Rekeying is an extra security measure whereby the broadcast WPA authentication key is automatically changed after a certain time period or after a certain number of packets have been sent. (Default: Disabled)•WPA Group-Key ReKey Interval – The elapsed time after which the wireless AP/Router will change the unicast WPA authentication key. (Default: 0; Range: 0~67108864)•WPA2 Pairwise Master Key Cache Interval – The elapsed time after which the wireless AP/Router will delete the WPA2 master keys from its security association cache. •WPA2 Pre-Authentication Support – Each time a client roams to another access point it has to be fully re-authenticated. This authentication process is time consuming and can disrupt applications running over the network. WPA2 includes a mechanism, known as pre-authentication, that allows clients to roam to a new access point and be quickly associated. The first time a client is authenticated to a wireless network it has to be fully authenticated. When the client is about to roam to another access point in the network, the access point sends pre-authentication messages to the new access point that include the client’s security association information. Then when the client sends an association request to the new access point, the client is known to be already authenticated, so it proceeds directly to key exchange and association. Pre-authentication support attaches a security flag to the packet header. (Default: Disabled)

System Configuration5-325RADIUSRemote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network.A RADIUS server must be specified for the access point to implement IEEE 802.1X network access control and Wi-Fi Protected Access (WPA) wireless security.Click "WLAN1/WLAN2 Security" and be sure that an "Enterprise" mode is selected.Note: This guide assumes that you have already configured RADIUS server(s) to support the access point. Configuration of RADIUS server software is beyond the scope of this guide, refer to the documentation provided with the RADIUS server software.Figure 5-21. RADIUS SettingsRADIUS Setting — Configures RADIUS server settings.Note: RADIUS settings only apply to WPA, WPA2, or WPA/WPA2 Enterprise modes.•RADIUS Server Network – Use the RADIUS Server Network options to specify if the server is located on the local area network, or wide area network. (Default: WAN)• RADIUS Server Address – Specifies the IP address of the RADIUS server.• RADIUS Server Port – The User Datagram Protocol (UDP) port number used by the RADIUS server for authentication messages. (Range: 1024-65535; Default: 1812)• RADIUS Server Key – A shared text string used to encrypt messages between the access point and the RADIUS server. Be sure that the same text string is specified on the RADIUS server. Do not use blank spaces in the string. (Maximum length: 20 characters)

Wireless Settings5-335WDS SettingsThe WLAN1 radio interface can be configured to operate in a mode that allows it to forward traffic directly to other access point units. To set up links between access point units, you must configure the Wireless Distribution System (WDS) forwarding table by specifying the wireless MAC address of all units to which you want to forward traffic.Traffic forwarded to WDS links is automatically converted to 802.11 four-address format frame. This uses the MAC addresses of the station and that of the AP connected to it on the transmitting LAN, and the MAC addresses of the AP functioning as a wireless repeater/bridge and that of the station connected to it on a neighboring LAN in the 802.11 frame header. Ethernet traffic follows a three-address format that is reconstructed for WDS transmission. The wireless AP/Router will reconstruct the frame format upon receival and transmission using the criteria of the receiving and forwarding port location and whether it is Ethernet or wireless in type.Note: The wireless AP/Router does not support the spanning tree algorithm. WDS links should be configured appropriately to avoid causing loops on the network.Up to four WDS links can be specified for each unit in the WDS network.The WDS link can be configured in the following combinations:1. Both two units are configured as Router Mode2. One unit is Router Mode and one unit is AP Bridge Mode3. Both two units are configured as AP Bridge ModeWhen both units are set to Router Mode, be sure to check these settings:• Be sure each unit is configured with a different LAN IP address.• Be sure that only one unit has Internet access on its WAN port.• Be sure the DHCP server is enabled only on one unit. If one unit is providing Internet access, enable the DHCP server on that unit.Note: WDS Settings only apply to WLAN1. WLAN2 is pre-configured to AP mode unless WLAN1 is configured to act as a bridge, in which case WLAN2 is disabled.Figure 5-22. WDS Settings

System Configuration5-345WDS Setting — Configures WDS related parameters. Up to four MAC addresses can be specified for each unit in the WDS network. WDS links may either be manually configured (Bridge and Repeater modes) or auto-discovered (Lazy mode).•WDS – Selects the WDS mode of WLAN1. (Default: Disabled)-Disabled: WDS is disabled.-Bridge: Operates as a standard bridge that forwards traffic between WDS links (links that connect to other AP/wireless bridges, or units in Repeater or Lazy mode) and an Ethernet port. Only data destined for stations which are known to be on the peer Ethernet link, multicast data or data with unknown destinations, need to be forwarded through the WDS link. The Bridge mode does not transmit a beacon, unlike the other three modes. In this mode the wireless AP/Router may also function as a repeater. Note: Enabling “Bridge” mode disables WLAN2.-Repeater – Operates as a wireless repeater, extending the range for remote wireless clients and connecting them to an AP connected to the wired network. WDS peers must be registered with the wireless AP/Router. Repeater mode also supports the dual capability of the VAP functioning as an AP. In this mode, traffic is not forwarded to the Ethernet port from the radio interface. In Repeater mode the wireless AP/Router transmits a beacon.-Lazy – Operates in an automatic mode that detects and learns WDS peer addresses from received WDS four-address format frame packets, without the need to configure a WDS MAC list entry. This feature allows the wireless AP/Router to associate with other wireless AP/Routers in the network and use their WDS MAC list. In Lazy mode the wireless AP/Router sends a beacon.•WDS Encryption Type – Sets the WDS encryption type, the options for which are determined by the Authentication Mode and the Encryption Type selected in the Security Settings.Note: When WDS is disabled or the WDS Encryption Type is set to "none," WDS encryption is also disabled.- When Authentication Mode is set to Open, Shared, or WEP auto; WEP is the only WDS encryption type.- When Authentication Mode is set to WPA Personal, or WPA2 Personal, the WDS encryption type may be TKIP or AES.- None: Disables WDS encryption.- WEP: Uses WEP keys for data encryption.-TKIP: Uses Temporal Key Integrity Protocol (TKIP) keys for encryption as a replacement for WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys.-AES: Uses Advanced Encryption Standard (AES) keys for encryption. Use of AES-CCMP encryption is specified as a standard requirement for WPA2. Before implementing WPA2 in the network, be sure client devices are upgraded to WPA2-compliant hardware.

Wireless Settings5-355-TKIP/AES: Use both TKIP and AES keys for encryption. WPA2 defines a transitional mode of operation for networks moving from WPA security to WPA2.WPA2 Mixed Mode allows both WPA and WPA2 clients to associate to a common SSID interface. In mixed mode, the unicast encryption cipher (TKIP or AES-CCMP) is negotiated for each client.•WDS WPA/WPA2 Pre-Shared Key – This option is available only when Authentication Mode is set to WPA Personal, WPA2 Personal or WPA/WPA2 Personal. Enter a key as an easy-to-remember form of letters and numbers. The WDS WPA/WPA2 Preshared Key can be input as ASCII string (8-63 characters) or Hexadecimal format (length is 64). Other bridge units must be configured with the same key to communicate with this unit.•WDS MAC List – The physical layer address of other bridge units for which this unit communicates as a network node. (12 hexadecimal digits in the form “xx:xx:xx:xx:xx:xx”)Note: In WDS Lazy mode any entries in the WDS MAC List are redundant because the MAC is pre-configured to 00:00:00:00:00:00.

System Configuration5-365MAC Access Control ListsWireless clients can be authenticated for network access by checking their MAC address against a local database configured on the wireless AP/Router. You can configure a list of up to 32 wireless client MAC addresses in the filter list to either allow or deny network access. MAC ACL configuration is the same for both WLAN1 and WLAN2.Figure 5-23. MAC FilterWLAN1/WLAN2 MAC Access Control Setting — Configures all MAC ACL parameters. (Maximum 64 entries are allowed.)• MAC Access Policy – The MAC address filter can be configured to allow or deny network access to listed clients. Select "Allow All but Reject those on MAC List" to permit access from all MAC addresses except those on the ACL list, or "Reject All but Allow those on MAC List" to block access from all MAC addresses except those on the ACL list. (Default: Disabled)•Submit – Implements the selected MAC Access Policy.• Reset – Restores the previous MAC Access Policy configuration information.•Enable – Activates the MAC address into the ACL. • MAC Address – MAC Address to filter, specified in the form of 12 hexadecimal digits, “xx:xx:xx:xx:xx:xx”.• Description – An optional parameter to help identify the selected MAC address. (Range: 1~16 characters)

Click "Change" to save parameters once you have updated them.-Add: Adds a newly configured MAC ACL entry to the list.-Edit: Click "Edit" to highlight a configured MAC ACL filtering rule for changing its parameters.-Delete: Deletes a MAC entry from the list.Associated Client List — Lists the MAC addresses of wireless clients currently associated to the wireless AP/Router.•MAC – A wireless client MAC address.• Description – An optional parameter that helps identify the MAC address of the associated client.

System Configuration5-385Wi-Fi Protected Setup (WPS)Wi-Fi Protected Setup (WPS) is designed to ease installation and activation of security features in wireless networks. WPS has two basic modes of operation, Push-button Configuration (PBC) and Personal Identification Number (PIN). The WPS PIN setup is optional to the PBC setup and provides more security. The WPS button on the wireless AP/Router can be pressed at any time to allow a single device to easily join the network.Note: WPS settings only apply to WLAN1.The WPS Settings page includes configuration options for setting WPS device PIN codes and activating the virtual WPS button.Figure 5-24. WPS SettingsWPS Settings — Enables WPS, locks security settings, and refreshes WPS configuration information.•WiFi Protected Setup – Enables WPS. (Default: Enabled)

Wireless Settings5-395•Lock Security Setting – Enabling this setting and clicking “Submit” or “Reset” allows the wireless AP/Router to retain the previous WPS negotiated security setup after a reboot or power off. Upon booting the unit will not re-authenticate clients that were retained in memory. Only new clients will require authentication. (Default: Disabled) •Submit – Enables the WPS configuration.•Reset – Restores the previous WPS configuration information.AP Security Information — Provides detailed WPS statistical information.•WPS Configured – States if WPS for wireless clients has been configured for this device. (Default: no)•WPS Status – Displays if there is currently any WPS traffic connecting to the wireless AP/Router. (Options: Start WSC Process; Idle; Default: Idle)•SSID – The service set identifier for WLAN1. (Default: mr3305a1)•Auth Mode – The method of authentication used. (Default: Open)•Encryption Type – The encryption type used for WLAN1. (Default: None)•WPAPSK – Displays the pre-shared key if WPA/WPA2 has been enabled. •Refresh – Refreshes the AP Security Information statistics.WPS Config — Configures WPS settings for the wireless AP/Router.•WPS Mode – The wireless AP/Router can be set as a registrar (master) device or an enrollee (client) device:-as Registrar: When the wireless AP/Router is set as the registrar device, enter the PIN code/s of the enrollee device/s and click “start WPS Config" to add the client/s to the network.Note: When the wireless AP/Router is the registrar device, the enrollee device can join the network by entering the wireless AP/Router’s PIN code “61773981.”-as Enrollee: When the wireless AP/Router is set as the enrollee device, the default PIN-Code for the unit is displayed. Click “start WPS Config" to join the network.•WPS Config Method – Selects between methods of broadcasting the WPS beacon to network clients wanting to join the network:-PIN: The wireless AP/Router, along with other WPS devices, such as notebook PCs, cameras, or phones, all come with their own eight-digit PIN code. When one device, the WPS enrollee, sends a PIN code to the wireless AP/Router, it becomes the WPS registrar. After configuring PIN-Code information you must press “start WPS Config" to send the beacon, after which you have up to two minutes to activate WPS on devices that need to join the network.

System Configuration5-405-PBC: This has the same effect as pressing the physical WPS button that is located on the front of the wireless AP/Router. After checking this option and clicking “Start WPS Config” you have up to two minutes to activate WPS on devices that need to join the network.• Add Enrollee PIN Code – In Registrar mode enter the PIN Code for the WDS device that wants to join the network.• PIN Code of this AP – In Enrollee mode this displays the PIN Code for the wireless AP/Router. The default is exclusive for each unit.•Start WPS Config – Sends a handshake beacon to devices wanting to join the network, for a duration of two minutes.

Routing5-415RoutingRouting setup allows a manual method that is used to set up routing between networks. The network administrator configures static routes in a router by entering routes directly into the routing table of a router. Static routing has the advantage of being predictable and easy configuration. Static RouteThis screen is used to manually configure static routes to other IP networks, subnetworks, or hosts. Click "Network Settings" followed by “static Route." (Maximum 32 entries are allowed.)Figure 5-25. Static Route (Router mode)•Enable – Enables the configured route. (Default: Disabled)•Target – A destination network or specific host to which packets can be routed.•Netmask – The subnetwork associated with the destination. This is a template that identifies the address bits in the destination address used for routing to specific subnets. Each bit that corresponds to a “1” is part of the network/subnet number; each bit that corresponds to “0” is part of the host number.•Gateway – The IP address of the router at the next hop to which matching frames are forwarded.•Action – Specifies an action to take on a static route.-Change: By selecting a configured route from the routing table its parameters display in an editable form. Click “Change” to save parameters once you have updated them.-Add: Adds a newly configured route to the list.-Edit: Click "Edit" to highlight an entry in the static MAC list for changing its parameters.-Delete: Deletes a static route from the list.

System Configuration5-425Dynamic RouteThe wireless AP/Router supports RIP 1 and RIP 2 dynamic routing protocol. Routing Information Protocol (RIP) is the most widely used method for dynamically maintaining routing tables. RIP uses a distance vector-based approach to routing. Routes are chosen to minimize the distance vector, or hop count, which serves as a rough estimate of transmission cost. Each router broadcasts its advertisement every 30 seconds, together with any updates to its routing table. This allows all routers on the network to build consistent tables of next hop links which lead to relevant subnets.Figure 5-26. Dynamic Route (Router mode)• WAN Interface – Specifies RIP1, RIP2, RIP1/RIP2, or disables the function for the WAN interface.•LAN Interface – Specifies RIP1, RIP2, RIP1/RIP2, or disables the function for the LAN interface.

Routing5-435Multicast RoutingMulticasting is used to support real-time applications such as videoconferencing or streaming audio. A multicast server does not have to establish a separate connection with each client. It merely broadcasts its service to the network, and any hosts that want to receive the multicast register with their local multicast router. Although this approach reduces the network overhead required by a multicast server, the broadcast traffic must be carefully pruned at every multicast network device it passes through to ensure that traffic is only passed on to the hosts that have subscribed to the service.This device uses IGMP (Internet Group Management Protocol) Snooping to monitor IGMP service requests passing between multicast clients and servers, and dynamically configure the ports that need to forward multicast traffic. Figure 5-27. Multicast Route (Router mode)IGMP Snooping — The wireless AP/Router can passively snoop on IGMP Query and Report packets transferred between IP multicast routers and IP multicast host groups to identify the IP multicast group members. It simply monitors the IGMP packets passing through it, picks out the group registration information, and configures the multicast filters accordingly.•Enable – Enables IGMP snooping on the wireless AP/Router.IGMP Proxy — Collects and sends multicast group membership information onto the upstream interface based on IGMP messages monitored on downstream interfaces, and forwards multicast traffic based on that information.•IGMP Proxy – Enables IGMP proxy on the wireless AP/Router.•Quick Leave – The wireless AP/Router can immediately delete a member port of a multicast service if a leave packet is received at that port.

System Configuration5-445WAN Multicast Routing — IP addresses of upstream multicast routers on the WAN interface. You can add, edit, and delete IP addresses from the list.•IP Address – Specifies an IP address to route to.•Net Mask – Specifies a network mask.FirewallThe wireless AP/Router provides extensive firewall protection by restricting connection parameters to limit the risk of intrusion and defending against a wide array of common hacker attacks.NATNetwork Address Translation (NAT) is a standard method of mapping multiple "internal" IP addresses to one "external" IP address on devices at the edge of a network. For the wireless AP/Router, the internal (local) IP addresses are the IP addresses assigned to PCs and wireless clients by the DHCP server, and the external IP address is the IP address assigned to the WAN port.If you configure the wireless AP/Router as a virtual server, remote users accessing services such as web or FTP at your local site through public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the wireless AP/Router redirects the external service request to the appropriate server (located at another internal IP address).For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the Private IP/Port to 192.168.2.2/80, then all HTTP requests from outside users will be transferred to 192.168.2.2 on port 80. Therefore, by just entering the IP address provided by the ISP, Internet users can access the service they need at the local address to which you redirect them.The more common TCP service port numbers include: HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110.Some applications, such as Internet gaming, videoconferencing, Internet telephony and others, require multiple connections. These applications cannot work with Network Address Translation (NAT) enabled. If you need to run applications that require multiple connections, use port mapping to specify the additional public ports to be opened for each application. Click "Network Settings" followed by "NAT."

System Configuration5-465•DMZ – Enables a specified host PC on the local network to access the Internet without any firewall protection. Some Internet applications, such as interactive games or videoconferencing, may not function properly behind the wireless AP/Router's firewall. By specifying a Demilitarized Zone (DMZ) host, the PC's TCP ports are completely exposed to the Internet, allowing open two-way communication. The host PC should be assigned a static IP address (which is mapped to its MAC address) and this must be configured as the DMZ LAN IP.• DMZ LAN IP – Specifies the IP address of the DMZ.• Non-standard FTP port – Enables routing of traffic through a non-standard FTP port.•Submit – Saves the current NAT configuration.•Reset – Restores the previous NAT configuration information.Virtual Server Mapping — Using the NAT Virtual Server Mapping feature, remote users can access different servers on your local network using your single public IP address.

(Maximum 32 entries are allowed.)•Enable – Enables port triggering on the specified ports. (Default: Disabled)• Trigger Port – Specifies the outbound port, or port range, for example “4040-4080.” (Range: 1~65535, or number1-number2)• Trigger Type – Specifies the trigger port type, TCP or UDP.

You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

License InformationC-2CWe protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.The precise terms and conditions for copying, distribution and modification follow.GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION1. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.2. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.3. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

The GNU General Public LicenseC-3Ca). You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.b). You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.c). If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.4. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:a). Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,b). Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

License InformationC-4Cc). Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.5. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.6. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.7. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.8. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a

The GNU General Public LicenseC-5Cconsequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.9. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.10. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.11. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

License InformationC-6CNO WARRANTY1. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.2. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.END OF TERMS AND CONDITIONS

Access points attached to a wired network, support the creation of multiple radio cells that enable roaming throughout a facility.Advanced Encryption Standard (AES)An encryption algorithm that implements symmetric key cryptography. AES provides very strong encryption using a completely different ciphering algorithm to TKIP and WEP.AuthenticationThe process to verify the identity of a client requesting network access. IEEE 802.11 specifies two forms of authentication: open system and shared key.Backbone The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is unloaded onto a local system.BeaconA signal periodically transmitted from the access point that is used to identify the service set, and to maintain contact with wireless clients.Broadcast KeyBroadcast keys are sent to stations using dynamic keying. Dynamic broadcast key rotation is often used to allow the access point to generate a random group key and periodically update all key-management capable wireless clients.Dynamic Host Configuration Protocol (DHCP)Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options.

Hypertext Transfer Protocol (HTTP)HTTP is a standard used to transmit and receive all data over the World Wide Web.IEEE 802.11bA wireless standard that supports wireless communications in the 2.4 GHz band using Direct Sequence Spread Spectrum (DSSS). The standard provides for data rates of 1, 2, 5.5, and 11 Mbps.IEEE 802.11gA wireless standard that supports wireless communications in the 2.4 GHz band using Orthogonal Frequency Division Multiplexing (OFDM). The standard provides for data rates of 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps. IEEE 802.11g is also backward compatible with IEEE 802.11b.IEEE 802.11nA wireless standard that supports wireless communications in the 2.4 GHz band using Orthogonal Frequency Division Multiplexing (OFDM). The standard provides for data rates of 27, 54, 81, 108, 162, 216, 243, 270, 300 Mbps. IEEE 802.11n is also backward compatible with IEEE 802.11b/g.InfrastructureAn integrated wireless and wired LAN is called an infrastructure configuration.Local Area Network (LAN)A group of interconnected computer and support devices.MAC AddressThe physical layer address used to uniquely identify network nodes. Network Time Protocol (NTP)NTP provides the mechanisms to synchronize time across the network. The time servers operate in a hierarchical-master-slave configuration in order to synchronize local clocks within the subnet and to national time standards via wire or radio.

Glossary-3GlossaryOpen SystemA security option which broadcasts a beacon signal including the access point’s configured SSID. Wireless clients can read the SSID from the beacon, and automatically reset their SSID to allow immediate connection to the nearest access point. Orthogonal Frequency Division Multiplexing (ODFM)OFDM allows multiple users to transmit in an allocated band by dividing the bandwidth into many narrow bandwidth carriers.Repeater and BridgeRepeater and bridge can provide an extended link to a remote access point from the wired LAN. Access Point working in this mode could connect to another AP in Access Point mode or Repeater and Bridge mode. Whenever there are two APs having wireless link together (one in Access Point or Repeater and Bridge mode, another using Repeater and Bridge mode), and also have wired link separately, these two APs are also working as “bridging” for the two wired links.Service Set Identifier (SSID)An identifier that is attached to packets sent over the wireless LAN and functions as a password for joining a particular radio cell; i.e., Basic Service Set (BSS). Session KeySession keys are unique to each client, and are used to authenticate a client connection, and correlate traffic passing between a specific client and the access point.Shared KeyA shared key can be used to authenticate each client attached to a wireless network. Shared Key authentication must be used along with the 802.11 Wireless Equivalent Privacy algorithm. Simple Network Time Protocol (SNTP)SNTP allows a device to set its internal clock based on periodic updates from a Network Time Protocol (NTP) server. Updates can be requested from a specific NTP server, or can be received via broadcasts sent by NTP servers.Temporal Key Integrity Protocol (TKIP)A data encryption method designed as a replacement for WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys. Trivial File Transfer Protocol (TFTP)A TCP/IP protocol commonly used for software downloads.

GlossaryGlossary-4Virtual Access Point (VAP)Virtual AP technology multiplies the number of Access Points present within the RF footprint of a single physical access device. With Virtual AP technology, WLAN users within the device’s footprint can associate with what appears to be different access points and their associated network services. All the services are delivered using a single radio channel, enabling Virtual AP technology to optimize the use of limited WLAN radio spectrum.Wi-Fi Protected AccessWPA employs 802.1X as its basic framework for user authentication and dynamic key management to provide an enhanced security solution for 802.11 wireless networks.Wired Equivalent Privacy (WEP)WEP is based on the use of security keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded from network traffic.WPA Pre-shared Key (WPA-PSK)WPA-PSK can be used for small office networks with a limited number of users that may not need a high level of security. WPA-PSK provides a simple security implementation that uses just a pre-shared password for network access.
