Static Route Example 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 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 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 precautionary security measure in case RIP is activated.

Static Route Example

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 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 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 precautionary security measure in case RIP is activated.

Enabling Trend Micro Antivirus Enforcement

If you installed the Trend Micro Client/Server Messaging Suite for SMB on your local network,

the firewall can enforce antivirus scanning. When Antivirus Enforcement is selected, local PCs
