manual abstract
• Your company’s network is 134.177.0.0. When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the gateway, and a second route was created to your local network for all 192.168.1.x addresses. With this configuration, if you try to access a device on the 134.177.0.0 network, your router forwards your request to the ISP. The ISP forwards your request to the company where you are employed, and the request will likely be denied by the company’s firewall. In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.1.100. The static route would look like Figure 5-8. In this example: • The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.0.x addresses. • The Gateway IP Address fields specify that all traffic for these addresses should be forwarded to the ISDN router at 192.168.1.100. • A metric value of 1 will work since the ISDN router is on the LAN. • Private is selected only as a precautionary security measure in case RIP is activated. Advanced Configuration v1.0, May 2007 108 Mbps Wireless Router WGT624 v4 Reference Manual Enabling Remote Management Access Using the Remote Management page, you can allow a user or users on the Internet to configure, upgrade, and check the status of your WGT624 v4 wireless router. Note: Be sure to change the router’s default configuration password to a very secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of letters (both uppercase and lowercase), numbers, and symbols. Your password can be up to 30 characters. To configure your router for remote management: 1. On the main menu, under the Advanced heading, select Remote Management. Figure 5-9 2. Select the “Turn Remote Management On” check box. 3. Specify which external addresses will be allowed to access the router’s remote management. Note: For enhanced security, restrict access to as few external IP addresses as practical. a. To allow access from any IP address on the Internet, select “Everyone”. Advanced Configuration v1.0, May 2007 108 Mbps Wireless Router WGT624 v4 Reference Manual b. To allow access from a range of IP addresses on the Internet, select an IP address range. Enter a beginning and ending IP address to define the allowed range. c. To allow access from a single IP address on the Internet, select Only This Computer. Enter the IP address that will be allowed access. 4. Specify the Port Number that will be used for accessing the management interface. Web browser access normally uses the standard HTTP service port 80. For greater security, you can change the remote management Web interface to a custom port by entering that number in the box provided. Choose a number between 1024 and 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP. 5. Click Apply to have your changes take effect. Note: When accessing your router from the Internet, you will type your router’s WAN IP address into your browser’s address (in IE) or location (in Netscape) box, followed by a colon (:) and the custom port number. For example, if your external address is 134.177.0.123 and you use port number 8080, you must enter in your browser. Using Universal Plug and Play (UPnP) Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network. Figure 5-10 Advanced Configuration v1.0, May 2007 108 Mbps Wireless Router WGT624 v4 Reference Manual • Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is enabled. If disabled, the router will not allow any device to automatically control the resources, such as port forwarding (mapping), of the router. • Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations will ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic. • Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it ma...
