5. Click Reset to discard any changes and revert to the previous settings.

For example, you may require a static route if:

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

• You have an ISDN firewall on your home network for connecting to the company where you

are employed. This firewall’s address on your LAN is 192.168.1.100.

• Your company’s network is 134.177.0.0.

When you first configured your firewall, two implicit static routes were created. A default route

was created with your ISP as the gateway, and a second static route was cre ated to your local

network for all 192.168.1.x addresses. With this c onfiguration, if you attempt to access a device on

the 134.177.0.0 network, your firewall 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 firewall that 134.177.0.0 should be accessed

through the ISDN firewall 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 fields specifies that all traffic for these addresses should be

forwarded to the ISDN firewall at 192.168.1.100.

• A Metric value of 1 will work since the ISDN firewall is on the LAN.

• Private is selected only as a precautionar y security measure in case RIP is activated.

Enabling Universal Plug and Play (UPnP)

Universal Plug and Play (UPnP) can improve the overall networking experience through automatic

discovery and device interoperability. UPnP helps devices, such as Internet appliances and

computers, access the network and connect to other devices as needed. UPnP devices can

automatically discover the services from other registered UPnP devices on the network.
