Setting Up Internal Static Routes

The Internal Network Setup Screen (Figure 4.12) lets you specify the set of internal networks and their gateways. You do not need to make an entry for the network that the internal interface of the firewall is directly attached to, but only for other internal networks that are connected to the firewall's internal network via gateways/routers (not LAN bridges).

 

  

Figure 4.12: The Internal Network Setup Screen

The fields in this screen are:

Address

The numeric IP address of the network (e.g. 192.168.1.16)

Gateway

The numeric IP address of the gateway between the network and the inside interface of the firewall.

Netmask

The address mask of the network (e.g. 255.255.255.240)

This information is used by the firewall to determine how to route traffic to internal hosts, as well as to determine whether a given IP address belongs to a host on the inside network, or on the outside network.
