Static routes provide additional routing information to your router. Under usual 
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 have to 
configure static routes only for unusual cases such as multiple routers or multiple IP subnets 
located 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 router on your home network for connecting to the company where 
you are employed. This 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 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 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 router that 134.177.0.0 should be 
accessed through the ISDN 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 router at 192.168.1.100. 

A metric value of 1 works because the ISDN router is on the LAN. 

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