Using Static Routes
Static Routes provide additional routing information to your router. Under normal circumstances,
the router has adequate routing information after it has been configured for Internet access, and
you do not need to configure additional static routes. You must configure static routes only for
unusual cases such as multiple routers or multiple IP subnets located on your network.

Static Route Example
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 router on your home network for connecting to the company where
you are employed. This router’s address on your LAN is 192.168.0.100.
you are employed. This router’s address on your LAN is 192.168.0.100.
•
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 ADSL modem wireless router, and a second static route was created
to your local network for all 192.168.0.x addresses. With this configuration, if you attempt to
access a device on the 134.177.0.0 network, your router will forward 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 192.168.0.100. The static route would look like
through the ISDN router at 192.168.0.100. The static route would look like
.
Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the
dynamic DNS service will not work because private addresses will not be routed
