Use 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 need to

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:

• Y

our primary Internet access is through a cable modem to an ISP.

• Y

ou 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.

• Y

our 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 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 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 need to define a static route, te

lling your router that 134.177.0.0 should be

accessed through the ISDN router at 192.168.0.100.

In this example:

• The Destina

tion IP Address and IP Subnet Mask fields specify that this static route

applies to all 134.177.x.x addresses.

• The Gateway IP Address f

ields specify that all traffic for these addresses should be

forwarded to the ISDN router at 192.168.0.100.

• In th

e Metric field, a value of 1 will work since the ISDN router is on the LAN.

This represents the number of routers between you

r network and the destination. This is

a direct connection, so it is set to 1.

• Private is se

lected only as a precautionary security measure in case RIP is activated.
