Custom Static Routes
Typically, you do not need to add static routes unless your network includes multiple routers
or multiple IP subnets.
or multiple IP subnets.
As an example of when a static route is needed, consider the following case:
•
Your main Internet access is through a cable modem to an ISP.
•
You use an ISDN cradle on your home network for connecting to the company where you
are employed. This cradle’s address on your LAN is 192.168.100.100.
are employed. This cradle’s address on your LAN is 192.168.100.100.
•
Your company’s network address is 134.177.0.0.
When you set up your cradle, 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 192.168.100.x addresses. With this configuration, if you try to access a device
on the 134.177.0.0 network, your cradle forwards your request to the ISP. The ISP forwards
your request to the company where you are employed, and the company firewall is likely to
deny the request.
created with your ISP as the gateway, and a second static route was created to your local
network for all 192.168.100.x addresses. With this configuration, if you try to access a device
on the 134.177.0.0 network, your cradle forwards your request to the ISP. The ISP forwards
your request to the company where you are employed, and the company firewall is likely to
deny the request.
In this case you must define a static route, telling your cradle to access 134.177.0.0 through
the ISDN cradle at 192.168.100.100. Here is an example:
the ISDN cradle at 192.168.100.100. Here is an example:
•
The Destination IP Address and IP Subnet Mask fields specify that this static route
applies to all 134.177.x.x addresses.
applies to all 134.177.x.x addresses.
•
The Gateway IP Address field specifies that all traffic for these addresses will be
forwarded to the ISDN cradle at 192.168.100.100.
forwarded to the ISDN cradle at 192.168.100.100.
•
A metric value of 1 works because the ISDN cradle is on the LAN.

The Private check box is selected only as a precautionary security measure in case RIP
