D6200 WiFi DSL Modem Router
Static Routes
Static routes provide more routing information to your WiFi DSL modem router. Under usual
circumstances, the WiFi DSL modem router has adequate routing information after it has
been configured for Internet access, and you do not need to configure more static routes.
You have to configure static routes only for unusual cases such as multiple WiFi DSL modem
routers or multiple IP subnets on your network.
As an example of when a static route is needed, consider the following case:
•Your primary Internet access is through a cable modem to an ISP.
•You have an ISDN WiFi DSL modem router on your home network for connecting to the
company where you are employed. This WiFi DSL modem router’s address on your LAN
is 192.168.1.100.
•Your company’s network address is 134.177.0.0.
When you first configured your WiFi DSL modem router, two implicit static routes were
created. A default route was created with your ISP as the gateway, and a second static route
was created to your local network for all 192.168.1.x addresses. With this configuration, if
you attempt to access a device on the 134.177.0.0 network, your WiFi DSL modem router
forwards your request to the ISP. The ISP forwards your request to the company where you
are employed, and the request is likely to be denied by the company’s firewall.
In this case you have to define a static route, telling your WiFi DSL modem router that
134.177.0.0 should be accessed through the ISDN WiFi DSL modem router at
192.168.1.100. In this example:
•The Destination IP Address and IP Subnet Mask fields specify that this static route
applies to all 134.177.x.x addresses.
•The Gateway IP Address field specifies that all traffic for these addresses should be
forwarded to the ISDN WiFi DSL modem router at 192.168.1.100.
•A metric value of 1 works since the ISDN WiFi DSL modem router is on the LAN.
•Private is selected only as a precautionary security measure in case RIP is activated.
