Static Routes
Static routes provide additional routing information to your modem router. Typically, you do
not need to add static routes. You have to configure static routes only for unusual cases such
as multiple 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.
• Y
ou have an ISDN modem router on your home network for connecting to the company
where you are employed. This modem router’s address on your LAN is 192.168.0.100.
• Y
our company’s network address is 134.177.0.0.
When you first configured your 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 192.168.0.x addresses. With this configuration, if you
attempt to access a device on the 134.177.0.0 network, your 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.
