SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 5 2. Gateway Overview Your gateway has many ports, switches and LEDs. Let’s take a look at the different options. Depending upon your model of gateway, your gateway may have some or all of the features listed below 2.1 Ports and Buttons (1 Port Ethernet Gateway) (1 Port Wireless Gateway) (4 Ports Ethernet Gateway) (4 Ports Wireless Gateway) RESET: The RESET button will set the gateway to its factory default setting and reset the gateway. You may need to place the gateway into its factory defaults if the configuration is changed, you loose the ability to enter the gateway via the web interface, or following a software upgrade, and you loose the ability to enter the gateway. To reset the gateway, simply press the reset button for more than 10 seconds. The gateway will be reset to its factory defaults and after about 30 seconds the gateway will become operational again. POWER: Connect the power adapter that came the Gateway. Using a power supply with a different voltage rating will damage this product. Make sure to observe the proper power requirements. The power requirement is 12 volts. LAN (local area network) port(s): Connect to Ethernet network devices, such as a PC, hub, switch, or router. Some gateways come with a single LAN connection and some come with four LAN connections. Depending on the connection, you may need a cross over cable or a strait through cable. USB (universal serial port): Connects this port to a PC’s USB port. The gateway only supports Window’s based PCs via an RNDIS driver (included in the software). ADSL port: This is the WAN interface which connects directly to your phone line.

WLAN LED: This LED is lighted when a wireless link is established and flashes when the data is sending/receiving via wireless. (wireless models) PPP LED: This LED is lighted when a PPP link is established and flashes when the data is sending/receiving via PPP. (Ethernet models) LAN LED: The LED is lighted when a connection is established to LAN port and flashes when LAN port is sending/receiving data. (The number of LAN ports depends on your model.) USB LED: The LED is lighted when a connection is established to USB port and flashes when USB port is sending/receiving data.

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 7 3. Installing Your Gateway 1. Locate an optimum location for the gateway. 2. For connections to the Ethernet and DSL interfaces, refer to the quick start guide. 3. Connect the AC Power Adapter. Depending upon the type of network, you may want to put the power supply on an uninterruptible supply. Only use the power adapter supplied with the gateway. A different adapter may damage the product. Now that the hardware installation is complete, proceed to Chapter 4: Setting up your gateway

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 8 4. Setting up Your Gateway This section will guide you through your gateway’s configuration. The gateway is shipped with a standard default bridge configuration; for most users, you may want to change the gateway from a bridge to a router. 4.1 Log into Your Gateway To configure your gateway, open your web browser. You may get an error message at this point; this is normal. Don’t panic. Continue following these directions. Type the default IP address (192.168.1.1) Press the Enter key and the following screen, shown in Figure 1 will appear. The default user name is Admin (case sensitive) and the password is Admin (case sensitive). Note: Before setting up your gateway, make sure you have followed the quick start guide. You should have your computers configured for DHCP mode and have proxies disabled on your browser. Also if you access the Gateway, and instead of getting a login screen, the browser instead displays a login redirection screen, you should check your browser's setting, and verify that JavaScript support is enabled. Also, if you do not get the screen shown in Figure 1, you may need to delete your temporary Internet files (basically flush the cached web pages). Figure 1 (Log-in screen)

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 9 4.2 Home Screen The first screen (Figure 2) that appears (after the log in screen) is the Home screen. From this screen the user can setup the modem (configure the LAN and WAN connection(s), configure the advanced configuration options within the modem (security, routing, and filtering), access tools that are helpful for debug purposes, obtain the status of the modem, and view the extensive online help. The basic layout of the Home page consists of a page selection list across the top of the browser window. The footer displays gateway status, connection information, and other useful information. The center display is where most of the configuration will take place. Figure 2 (Home page)

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 10 4.3 Setup To setup your gateway with a basic configuration, from the Home page, select Setup. Figure 3 illustrates the setup page. The page is broken into two subsections the WAN configuration and the LAN configuration. Before configuring the Gateway, there are several concepts that you should be familiar with on how your new Gateway works. Please take a moment to familiarize yourself with these concepts, as it should make the configuration much easier. Figure 3 (Setup page) 4.3.1 Wide Area Network Connection On the other side of the Gateway is where your Wide Area Network (WAN) connection; also referred to as a broadband connection. This WAN connection is different for every WAN supplier. Most of the configuration you will perform will be in this area. 4.3.2 Local Area Network Connection On one side of your Gateway, you have your own Local Area network (LAN) connections. This is where you plug in your local computers to the Gateway. The Gateway is normally configured to automatically provide all the PC's on your network with Internet addresses. 4.4 Configuring the WAN Before the gateway will pass any data between the LAN interface(s) and the WAN interface, the WAN side of the modem must be configured. Depending upon your DSL service provider or your ISP, you will need some (or all) of the information outlined below before you can properly configure the WAN: • Your DSL line VPI and VCI • Your DSL encapsulation type and multiplexing • Your DSL training mode (default is MMODE)

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 12 (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.4.1.2 PPPoA Connection Setup PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells which are carried over the DSL line. PPP or Point-to-Point protocol is a method of establishing a network connection / session between network hosts. It usually provides a mechanism of authenticating users. LLC and VC are two different methods of encapsulating the PPP packet. Contact your ISP to make sure which encapsulation is being supported. By selecting PPPoA, you are forcing your gateway to terminate the PPPoA connection. The advantage is that the PPPoA termination is done within the gateway and not on your PC; this frees up your PC resources and allows multiple users to utilize the PPPoA connection. To configure the gateway for PPPoA, click on Setup and then click on New Connection. The default PPPoE connection setup is displayed. At the Type field select PPPoA and the PPPoA connection setup page is displayed; figure 5 illustrates a typical PPPoA configuration. Give your PPPoA connection a unique name; the name must not have spaces and cannot begin with numbers. In this case the unique name is called PPPOA1. Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select the VPI and VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL service provider is using 0,40. Also select the quality of service (QOS); leave the default value if you are unsure or the ISP did not provide this information. Following is a description of the different options: a. Username: The username for the PPPoA access; this is provided by your DSL service provider or your ISP. b. Password: The password for the PPPoA access; this is provided by your DSL service provider or your ISP. c. On-Demand: Enables on-demand mode. The connection will disconnect if no activity is detected after the specified idle timeout value. d. Idle Timeout: Specifies that PPPoA connection should disconnect if the link has no activity detected for n seconds. This field is used in conjunction with the On-Demand feature. To ensure that the link is always active, enter a 0 in this field. e. Keep Alive: When on-demand option is not enable, this value specifies the time to wait without being connected to your provider before terminating the connection. To ensure that the link is always active, enter a 0 in this field. f. Maxfail: As long as a DSL connection is established, the gateway will attempt to establish a PPPoA connection. If after n consecutive failed connection attempts the gateway will wait for some random time before trying to establish the connection again. A value of 0 means no limit. g. Set Route: Specify this connection as the default-route. h. MRU: Maximum Receive Unit the DSL connection can receive. It is a negotiated value that asks the provider to send packets of no more than n bytes. The maximum specified value is 1500 although some DSL/ISP providers require a larger value. The minimum MRU value is 128. i. Debug: Enables PPPoA connection debugging facilities. Debugging is talked about later.

The apply button will temporarily save this connection. To make the change permanent you need to click on Tools (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.4.1.3 PPPoE Connection Setup PPPoE is also known as RFC 2516. It is a method of encapsulating PPP packets over Ethernet. PPP or Point-to-Point protocol is a method of establishing a network connection/session between network hosts. It usually provides a mechanism of authenticating users. To configure the gateway for PPPoE, click on Setup and then click on New Connection. The default PPPoE connection setup is displayed. At the Type field select PPPoE and the PPPoE connection setup page is displayed; figure 6 illustrates a typical PPPoE configuration. Give your PPPoE connection a unique name; the name must not have spaces and cannot begin with numbers. In this case the unique name is called PPPOE1. Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select the VPI and VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL service provider is using 0,30. Also select the quality of service (QOS); leave the default value if you are unsure or the ISP did not provide this information. Following is a description of the different options: j. Username: The username for the PPPoE access; this is provided by your DSL service provider or your ISP. k. Password: The password for the PPPoE access; this is provided by your DSL service provider or your ISP. l. On-Demand: Enables on-demand mode. The connection will disconnect if no activity is detected after the specified idle timeout value. m. Idle Timeout: Specifies that PPPoE connection should disconnect if the link has no activity detected for n seconds. This field is used in conjunction with the On-Demand feature. To ensure that the link is always active, enter a 0 in this field.

Keep Alive: When on-demand option is not enable, this value specifies the time to wait without being connected to your provider before terminating the connection. To ensure that the link is always active, enter a 0 in this field. o. Maxfail: As long as a DSL connection is established, the gateway will attempt to establish a PPPoE connection. If after n consecutive failed connection attempts the gateway will wait for some random time before trying to establish the connection again. A value of 0 means no limit. p. Set Route: Specify this connection as the default-route. q. MRU: Maximum Receive Unit the DSL connection can receive. It is a negotiated value that asks the provider to send packets of no more than n bytes. The maximum specified value is 1500 although some DSL/ISP providers require a larger value. The minimum MRU value is 128. r. Enforce MRU: Check this box if you experience problems accessing the Internet over a PPPoE connection. This feature will force all TCP traffic to conform with PPP MRU by changing TCP Maximum Segment Size to PPP MRU. s. Debug: Enables PPPoE connection debugging facilities. Debugging is talked about later. Figure 6 (PPPOE Connection Setup) To complete the connection you must now click the apply button. The apply button will temporarily save this connection. To make the change permanent you need to click on Tools (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.4.1.4 DHCP Connection Setup Dynamic Host Configuration Protocol (DHCP) allows the gateway to automatically obtain the IP address from the server. This option is commonly used in situations where IP is dynamically assigned and is not known prior to assignment.

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 15 To configure the gateway for a DHCP connection, click on Setup and then click on New Connection. The default DHCP connection setup is displayed. At the Type field select DHCP and the DHCP connection setup page is displayed; figure 7 illustrates a typical DHCP configuration. Give your DHCP connection a unique name; the name must not have spaces and cannot begin with numbers. In this case the unique name is called DHCP1. Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select the VPI and VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL service provider is using 0,35. Also select the quality of service (QOS); leave the default value if you are unsure or the ISP did not provide this information. If your DSL line is connected and your DSL/ISP provider is supporting DHCP, you can click the renew button and the gateway will retrieve an IP address, Subnet mask, and Gateway address. At anytime, you can renew the DHCP address by clicking on the renew button; in most cases you will never have to use this button. Figure 7 (DHCP Connection Setup) To complete the connection you must now click the apply button. The apply button will temporarily save this connection. To make the change permanent you need to click on Tools (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.4.1.5 Static Connection Setup Static is used whenever a known static IP is assigned. The accompanying information such as the Subnet mask and the gateway should also be specified. Up to three Domain Name Server (DNS) addresses can also be specified. These servers would enable you to have access to other web servers. Valid IP addresses range is from 0.0.0.0 to 255.255.255.255.

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 18 4.5 Configuring the WLAN Before you can use the wireless to access Internet or wire LAN via the modem, you must enable the AP functionality of this modem first. You can enable it following below setting, Setup Æ Wireless Æ Enable AP. Then you can select a channel to use and entry your AP’s SSID. Note: you must Restart Access Point for Wireless changes to take effect. Enable AP: enable/disable AP functionality Channel: select the working channel this AP will used SSID: service set ID Advanced: additional parameter setting

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 19 Following is a description of the different options: Beacon Period: Beacon is a special broadcast packet sent by AP, the unit is 1024 us DTIM Period: Delivery Traffic Indication Message (DTIM), if AP have broadcast packets need to transmit in Beacon packet will include this parameter, to indicates the number of Beacon intervals between successive DTIMs, default value is 2 RTS Threshold: if the packet size is large than this value, AP will start RTS/CTS transmitted, default value is 2347 bytes Frag Threshold: if the packet size is large than this value, AP will fragment this packet, default value is 2346 bytes Power Level: adjust the Tx power level, there have 5 levels you can choice, Full, 50%, 25%, 12% and 6%, default is Full power b/g Mode: select the operation mode of wireless, Mixed (b and g), b only, b+ (22M) and g only, default is Mixed Hidden SSID: by default SSID information will include in the beacon packet to notice user, for security issue you can remove SSID from beacon. 4.6 Configuring the LAN By default, your gateway has DHCP server (LAN side) enabled. If you already have a DHCP server running on your network, you must disable one of the two DHCP servers; if you plug a second DHCP server into the network, you will experience network errors and the network will not function normally.

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 20 4.6.1 Enable/Disable DHCP To enable or disable DHCP go to the Home screen, Click setup. Under LAN Setup, select DHCP Configuration. This will bring up the screen shown in Figure 10. The Start IP Address is where the DHCP server starts issuing IP addresses. This value must be greater than the gateways IP address value. For example if the gateways IP address is 192.168.1.1 (default) than the starting IP address must be 192.168.1. 2 (or higher). The End IP Address is where the DHCP server stops issuing IP addresses. The ending address cannot exceed a subnet limit of 254. Hence the max value for our default gateway is 192.168.1.254. If the DHCP server runs out of DHCP addresses, users will not get access to network resources. If this happens you can increase the Ending IP address (to the limit of 255) or reduce the lease time. The Lease Time is the amount of time a network user will be allowed connection to the Gateway with their current dynamic IP address. The amount of time is in units of seconds; the default value is 3600 seconds (1 hour). Note: If you change the start or end values, make sure the values are still within the same subnet as the gateways IP address. In other words, if the gateways IP address is 192.168.1.1 (default) and you change the DHCP start/end IP addresses to be 192.128.1.2/192.128.1.100, you will not be able to communicate to the gateway if your PC has DHCP enabled. Figure 10 (DHCP Server configuration)

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 21 In addition to the DHCP server feature, the gateway supports the DHCP relay function. When the gateway is configured as DHCP server, it assigns the IP addresses to the LAN clients. When the gateway is configured as DHCP relay, it is responsible for forwarding the requests and responses negotiating between the DHCP clients and the server. See figure 11. Figure 11 (Example of a DHCP Relay configuration) By turning off the DHCP server and relay the network administrator must carefully configure the IP address, Subnet Mask and DNS settings of every computer on your network. Do not assign the same IP address to more than one computer and your Gateway must be on the same subnet as all the other computers. The apply button will temporarily save this connection. To make the change permanent you need to click on Tools (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.6.2 Changing the gateways IP address You can change the gateway’s IP address by going to the Home screen, click setup and under LAN Setup, select Management. This will bring up the screen shown in Figure 12. 4.6.2.1 Static IP address assignment Your gateway’s default IP address and subnet mask are 192.168.1.1/255.255.255.0; this subnet mask will allow the gateway to support 254 users. If you want to support a larger number of users you can change the subnet mask; but remember. The DHCP server is defaulted to only give out 255 IP addresses. Further remember that if you change your gateways’ IP address and you have DHCP enabled, the DHCP configuration must reside within the same subnet. The default gateway is the routing device used to forward all traffic that is not addressed to a station within the local subnet. Your ISP will provide you with the default gateway Address. Figure 12 shows a default gateway address of 10.247.16.1 because this was the default gateway defined when the CLIP connection was configured. The hostname can be any alphanumeric word that does not contain spaces. The domain name is used to in conjunction with the host name to uniquely identify the gateway. To access the gateway’s web pages the user can type 192.168.1.1 (the gateway’s default IP address) or type mygateway.ar7.

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 30 4.7.4 Port Forwarding Using the Port Forwarding page, you can provide local services (for example web hosting) for people on the Internet or play Internet games. When users send this type of request to your network via the Internet, the Gateway will forward those requests to the appropriate PC. Port forwarding can be used with DHCP assigned addresses but remember that a DHCP address is dynamic (not static). For example, if you were configuring a netmeeting server, you would want to assign this server a static IP address so that the IP address is not reassigned. Also remember that if an Internet user is trying to access an Internet application, they must use the WAN IP address. The port forwarding will translate the WAN IP address into a LAN IP address. To configure a service, game, or other application select the external connection (for example the Internet connection), from the Home screen, click Advanced and under Advanced, select Port Forwarding. Next select the computer hosting the service and add the corresponding firewall rule. If you want to add a custom application, select the User category, click New and fill in the port, protocols and description for your application. For example, if you want to host a Netmeeting session, from the Home screen, click Advanced and under Advanced, select Port Forwarding. First select the IP address for your Netmeeting server. Next select the Audio/Video category and add Netmeeting to the applied rules box. To view the management rules, highlight Netmeeting and select view; this will display the pre configured protocols and ports that Netmeeting will use. Now assuming that your WAN connection is correct, you can run Netmeeting from your server and call users that are on the Internet. If you know your WAN IP address, users can call you. Figure 14 illustrates a typical Port Forwarding configuration. Figure 14 (Port Forwarding: Netmeeting) The apply button will temporarily save this connection.

At the system commands page, click on Save All. 4.7.5.1 DMZ configuration Setting a computer (on your local network) as a DMZ forwards any network traffic that is not redirected to another computer via the port-forwarding feature to the computer's IP address. This opens the access to the DMZ computer from the Internet. 4.7.5.2 Enable Remote Web Enabling the Remote Web on your local network allows Web requests that come from the Internet to be re-routed to a Web Server that is on a different subnet. This is different that the Web server rule that is configurable via the port-forwarding page. In this case, the web server is on a different subnet.

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 32 4.7.5.3 Enable Remote Telnet Enabling the Remote Web on your local network allows telnet requests that come from the Internet to be re-routed to a telnet Server that is on a different LAN IP subnet. This is different that the telnet server rule that is configurable via the port-forwarding page. In this case, the telnet server is on a different subnet. 4.7.5.4 Enable Incoming ICMP Ping Enabling the Incoming Internet Control Message Protocol (ICMP) Ping will allow Echo requests to come into the gateway. The gateway will respond with an ICMP Echo response message. The option allows the DSL provider or ISP to determine the following: a. The status of the network. b. Tracking and isolating hardware and software problems. c. Testing, measuring, and managing networks. 4.7.6 Access Control Access control can also be called port blocking. Specific types of traffic that is destined to a selected LAN IP address can be blocked. To enable any of the Access Control features, from the Home screen, click Advanced and under Advanced, select Access Control. A page similar to the port-forwarding page appears. Similar to the port-forwarding page, an IP address can be added to a rule. All Access Control rules have precedence over rules that were added via the port-forwarding page. The apply button will temporarily save this connection. To make the change permanent you need to click on Tools (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.7.7 LAN clients To add a LAN client, from the Home screen, click Advanced and under Advanced, select LAN Clients. If DHCP is used, all DHCP clients are automatically assigned. If a fixed IP address server is on the LAN and you want this server to be visible via the WAN, you must add its IP address. Once the IP address has been added to you can apply Port Forwarding and Access Control rules to this IP address. The apply button will temporarily save this connection. To make the change permanent you need to click on Tools (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.7.8 Bridge Filters The bridge filtering mechanism provides a way for the users to define rules to allow/deny frames through the bridge based on source MAC address, destination MAC address and/or frame type. When bridge filtering is enabled, each frame is examined against the defined filter rules sequentially, and when a matched is determined, the appropriate filtering action (determined by the access type selected ... i.e. allow or deny) is performed. The user should note that the bridge filter will only examined frames from interfaces which are part of the bridge itself. Twenty filter rules are supported with bridge filtering. To enable Bridge Filters, from the Home screen, click Advanced and under Advanced, select Bridge Filters. Figure 16 illustrates a typical Bridge filter configuration.

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 33 The User Interface for Bridge Filter allows the user to add/edit/delete, as well as, enables the filter rules. To add rules, simply define the source MAC address, destination MAC address and frame type with desired filtering type (i.e. allow/deny), and press the “Add” button. The MAC address must be in a xx-xx-xx-xx-xx-xx format, with 00-00-00-00-00-00 as “don’t care”. Blanks can be used in the MAC address space, and would be considered also as “don’t care”. To edit/modify an existing filter rule, select the desired rule created previously from “Add” in the “Edit” select box. The selected filter rule will appear on top section, as with the “Add” filter rule. Make the desired change to the MAC address, frame type and/or access type, and press “Apply”. To delete filter rule(s), select the filter rule entry to delete in the “Delete” selection box. Note that multiple deletions are possible. Once all the desired filter rule(s) is/are selected for deletion, press the “Apply” button. The “Select All” select box can also be used to delete the entire filter rule. It provides a quick method of selecting all filter rules for deletion. The “Enable Bridge Filters” button allow the user to enable or disable bridge filtering. It can be set/unset during any add/edit/delete operation. It can also be set/unset independently by just pressing the “Apply” button. Figure 16 (Bridge Filters) Note: The bridge filter table contains 3 hidden rules. These rules are entered automatically by the system to ensure the user does not "lock" them out of the system. The first rule allows any and all ARP frames through the system. The second rule allows all IPv4 frames with the destination MAC address of the bridge to go through. The third rule allows all IPv4 frames with the source MAC address of the bridge to go through.

At the system commands page, click on Save All. 4.7.9 Multicast Multicasting is a form of limited broadcast. UDP is used to send datagrams to all hosts that belong to what is called a "host group." A host group is a set of zero or more hosts identified by the same destination IP address. The following statements apply to host groups. a. Anyone can join or leave a host group at will. b. There are no restrictions on a host's location. c. There are no restrictions on the number of members that may belong to a host group. d. A host may belong to multiple host groups. e. Non-group members may send UDP datagrams to the host group. Multicasting is useful when data needs to be sent to more than one other device. For instance, if one device is responsible for acquiring data that many other devices need, then multicasting is a natural fit. Note that using multicasting as opposed to sending the same data to individual devices uses less network bandwidth. To enable Multicasting, from the Home screen, click Advanced and under Advanced, select Muliticast. Figure 17 illustrates a typical Multicast configuration.

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 35 4.7.10 Static Routing If the Gateway is connected to more than one network, you may need to set up a static route between them. A static route is a pre-defined pathway that network information must travel to reach a specific host or network. You can use static routing to allow different IP domain users to access the Internet through the Gateway. The New Destination IP is the address of the remote LAN network or host to which you want to assign a static route. Enter the IP address of the host for which you wish to create a static route here. For a standard Class C IP domain, the network address is the first three fields of the New Destination IP, while the last field should be 0. The Subnet Mask identifies which portion of an IP address is the network portion, and which portion is the host portion. For a full Class C Subnet, the Subnet Mask is 255.255.255.0. The Gateway IP address should be the IP address of the gateway device that allows for contact between the Gateway and the remote network or host. The Hop Count determines the maximum number of steps between network nodes that data packets will travel. A node is any device on the network (such as a router or switch). To enable Static Routing, from the Home screen, click Advanced and under Advanced, select Static Routing. Figure 18 illustrates a typical Static Route.

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 36 4.7.11 Dynamic Routing Dynamic Routing allows the Gateway to automatically adjust to physical changes in the network. The Gateway, using the RIP protocol, determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network. The Direction determines the direction that RIP routes will be updated. Selecting In means that the Gateway will only incorporate received RIP information. Selecting Out means that the Gateway will only send out RIP information. Selecting both means that the Gateway will incorporate received RIP information and send out updated RIP information. The protocol is dependent upon the entire network. Most networks support Rip v1. If RIP v1 is selected, routing data will be sent in RIP v1 format. If Rip V2 is selected, routing data will be sent in RIP v2 format using subnet broadcasting. If Rip V1 Compatible is selected, routing data will be sent in RIP v2 format using multicasting. To enable Dynamic Routing, from the Home screen, click Advanced and under Advanced, select Dynamic Routing. Figure 19 illustrates a typical Dynamic Route.

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 37 4.8 Tools The gateway supports a host of tools which will allow you to customize and debug your gateway. 4.8.1 System Commands To make the changes permanent you need to click on Tools (at the top of the page) and select System Commands. The following commands are used to configure the gateway: a. Save all: Press this button in order to permanently save the current configuration of the Gateway. If you do re-start the system without saving your configuration, the Gateway will revert back to the previously saved configuration. b. Restart: Use this button to re-start the system. If you have not saved your configurations, the Gateway will revert back to the previously saved configuration upon re-starting. NOTE: Connectivity to the unit will be lost. You can reconnect after the unit reboots. c. Restore Defaults: Use this button to restore factory default configuration. NOTE: Connectivity to the unit will be lost. You can reconnect after the unit reboots. 4.8.2 Remote Log The remote log feature is used in conjunction with the PC tool (software provided with your gateway). For PPPoE and PPPoA connections, you can select debug if you want to log the connection information. This is helpful when trying to debug connection problems. The remote log feature will forward all logged information to the remote PC. The type of information forwarded to the remote PC depends upon the Log level. Each log message is assigned a severity level, which indicates how seriously the triggering event affects Gateway functions. When you configure logging, you must specify a severity level for each facility; messages that belong to the facility and are rated at that level or higher are logged to the destination. Table 1 defines the different severity levels. To forward logging information, you need to click on Tools (at the top of the page) and select Remote Log. Table 1 (Severity Level)

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 38 4.8.3 User Management You can change your gateway’s username and password by going to the Home screen, under the tools menu, click User Management. From here you can change the login name and password. You can also change the idle timeout; you will need to log back onto the gateway once the timeout expires. If you forget your password, you can press and hold the reset to factory defaults button for 10 seconds (or more). The gateway will reset to its factory default configuration and all custom configurations will be lost. The apply button will temporarily save this connection. To make the change permanent you need to click on Tools (at the top of the page) and select System Commands. At the system commands page, click on Save All. 4.8.4 Update Gateway You can remotely upgrade the gateway’s firmware by going to the Home screen, under the tools title, click Update Gateway. This will bring up the screen shown in Figure 19. SOHOSpeed ADSL Gateway will provide two different images; one image is the kernel (operating system) and the other image is the file system. To upgrade the firmware, click browse, find the firmware file to download. Make sure this is the correct file. Click on upgrade firmware (as shown in Figure 20). Once the upgrade is complete the gateway will reboot. You will need to log back onto the gateway after the firmware upgrade is complete. The firmware upgrade should take less that 5 minutes to complete. If it takes longer than 5 minutes, something has gone wrong. Note: Do not remove power from the gateway during the firmware upgrade procedure. Figure 20 (Update Gateway)

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 39 4.8.5 Ping Test Once you have your gateway configured, it is a good idea to make sure you can Ping the network. You can get to the Ping web page by going to the Home screen, under the Tools title, click Ping Test. Type the target address that you want to pin. If you have your PC connected to the gateway via the default DHCP configuration, you should be able to Ping the network address 192.168.1.1. If your ISP has provided their server address you can try to ping the address. If the pings for both the WAN and the LAN side complete, and you have the proper protocols configured, you should be able to surf the Internet. By default when you select ping test, the gateway will ping itself 3 times. As shown in Figure 21, the gateway passed the Ping test; this basically means that the TCP/IP protocol is up and running. If this first Ping test does not pass, the TCP/IP protocol is not loaded for some reason; you should restart the modem. Figure 21 (Ping test) 4.8.6 Modem Test The Modem Test is used to check whether your Modem is properly connected to the WAN Network. This test may take a few seconds to complete. To perform the test, select your connection from the list and press the Test button. Before running this test, make sure you have a valid DSL link; if the DSL link is not connected, this test will always fail. Also the DSLAM must support this feature; not all DSLAMs have F4 and F5 support. 4.8.7 UI Support If you are having difficulty viewing the gateways’ web pages, you can change the resolution. You can get to the UI support page by going to the Home screen, under the Tools title, click UI support. The modem supports 640x480, 800x600, and 1024x780 (default).

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 41 5. Appendix A: Troubleshooting Below is a list of commonly asked questions. Before calling technical support, please look through these issues to see if they help solve your problem. 5.1 The gateway is not functional. 1. Check to see that the power LED is green and than the network cables are installed correctly. Refer to the quick start guide for more details. 2. Check to see that the LAN and WAN LEDs are green. 3. Check to see that the DSL LED is green 4. Make sure you are not connecting the USB and the Ethernet port at the same time. You must only use 1 interface at a time. 5. Check the settings on your PC. Again, refer to the quick start guide for more details 6. Check the gateway’s settings. 7. From your PC, can you PING the gateway? Assuming that the gateway has DHCP enabled and your PC is on the same subnet as the gateway, you should be able to PING the gateway. 8. Can you PING the WAN? Your ISP should have provided the IP address of their server. If you can ping the gateway and your protocols are configured correctly, you should be able to ping the ISPs network. If you cannot PING the ISPs network, make sure your using the correct protocols with the correct VPI/VCI values. 9. Make sure NAT is enabled for your connection. If NAT is disabled you the gateway will not route frames correctly. 5.2 I can’t connect to the gateway. 1. Check to see that the power LED is green and that the network cables are installed correctly; see the quick start guide for more details. 2. Make sure you are not connecting the USB and the Ethernet port at the same time. You must only use 1 interface at a time. 3. Make sure that your PC and the gateway is on the same network segment. The gateway’s default IP address is 192.168.1.1. If you are running a Windows based PC, you can open a DOS window and type IPCONFIG; make sure that the network adapter that is connected to the gateway is within the same 192.168.1.x subnet. 4. Also, your PC’s Subnet Mask should match the gateways subnet mask. The gateway has a default subnet mask of 255.255.255.0. 5. If this still does not work, press the reset button for 10 seconds. This will place the gateway into its factory default state. Go through the above procedures again. 6. Make sure NAT is enabled for your connection. If NAT is disabled you the gateway will not route frames correctly.

SOHOSpeed ADSL Ethernet/Wireless Gateway User’s Manual 42 5.3 The LEDs blink in a sequential pattern. This typically means that either the kernel or flash file system is corrupted. The only way to recover from this type of failure is via the PC tool. You need to install the PC tool that was provided with SOHOSpeed ADSL Gateway and perform the following steps: 1. In windows disable all network adapters except the one, which is connected to the gateway. 2. Disable zone alarm or any IP blocking software that is running of the PC. 3. Run the PC tool application. At the IP address prompt, type 192.168.1.1 and retrieve/assign IP address. The PC application should come back with information about the gateway. You then need to load the kernel image, flash file system, and config.xml file to the flash. 4. Once all three codes have been loaded into the gateway, the gateway will automatically reboot. As long as there is no problem with the Flash memory, the gateway should be functional and the LEDs should light correctly. 5.4 The DSL Link LED continues to blink but does not go solid. 1. This means that the DSL line is trying to train but for some reason it cannot establish a valid connection. The main cause of this is that you are too far away from the central office. Contact your DSL service provider for further assistance. 5.5 The DSL Link LED is always off. 1. Make sure you have DSL service. You should get some kind of information from your ISP which states that DSL service is installed. You can usually tell if the service is installed by listening to the phone line; you will hear some high-pitched noise. If you do not hear high-pitched noise, contact your ISP. 2. Verify that the phone line is connected directly to the wall and to the line input on the gateway. If the phone line is connected to the phone side of the gateway or you have a splitter installed on the phone line, the DSL light will not come on.

SOHOSpeed ADSL Ethernet/Wireless Router User’s Guide 43 6. Gateway terms What is a firewall? A firewall is protection between the Internet and your local network. It acts similarly to the firewall in your car, protecting the interior of the car from the engine. Your car's firewall has very small opening that allow desired connections from the engine into the cabin (gas pedal connection, etc), but if something happens to your engine, you are protected. The firewall in the Gateway is very similar. Only the desired connections that you allow are passed through the firewall. These connections are normally originating from the local network; such as web browsing, checking your email, downloading a file, and playing a game. However, in some cases, you can allow incoming connections so that you can run programs like a web server. What is NAT? NAT stands for Network Address Translation. Another name for it is Connection Sharing. What does this mean? Your ISP provides you with a single network address for you to access the Internet through. However, you may have several machines on your local network that want to access the Internet at the same time. The Gateway provides NAT functionality that converts your local network addresses to the single network address provided by your ISP. It keeps track of all these connections and makes sure that the correct information gets to the correct local machine. Occasionally, there are certain programs that don't work well through NAT. Some games, and some specialty applications have a bit of trouble. The Gateway contains special functionality to handle the vast majority of these troublesome programs and games. NAT does cause problems when you want to run a SERVER though. When running a server, please see the DMZ section below. What is a DMZ? DMZ really stands for Demilitarized Zone. It is a way of separating out part of your local network so that is more open to the Internet. Suppose that you want to run a web-server, or a game server. Normal servers like these are blocked from working by the NAT functionality. The solution is to "isolate" the single local computer into a DMZ. This makes the single computer look like it is directly on the Internet, and others can access this machine. Your machine isn't really directly connected to the Internet, and it really has an internal local network address. When you provide the servers network address to others, you must provide the address of the Gateway. The Gateway "fakes" the connection to your machine. You should use the DMZ when you want to run a server that others will access from the Internet. Internal programs and servers (like print servers, etc) should NOT be connected to the DMZ What is a Gateway? The Internet is so large that a single network cannot handle all of the traffic and still deliver a reasonable level of service. To overcome this limitation, the network is broken down into smaller segments or subnets that can deliver good performance for the stations attached to that segment. This segmentation solves the problem of supporting a large number of stations, but introduces the problem of getting traffic from one subnet to another. To accomplish this, devices called routers or gateways are placed between segments. If a machine wishes to contact another device on the same segment, it transmits to that station directly using a simple discovery technique. If the target station does not exist on the same segment as the source station, then the source actually has no idea how to get to the target. One of the configuration parameters transmitted to each network device is its default gateway. This address is configured by the network administrators and it informs each personal computer or other network device where to send data if the target station does not reside on the same subnet as the source. If your machine can reach all stations on the same subnet (usually a building or a sector within a building), but cannot communicate outside of this area, it is usually because of an incorrectly configured default gateway.
