Figure 4.48: The Address Group Setup Screen

The Address Groups Setup Screen can be used to add or delete address groups. Each address group has a name, and it is the names that are configured here. To add or remove addresses from a particular group, you need to move the cursor onto the group name and press F4. This will bring up the Address Group Setup Screen (Figure 4.48).

To use an address group when setting up a TCP proxy or TCP/UDP gateway, enter the group name surrounded by square brackets in place of an address. If a group name is specified in place of an address when setting up a service, the `Bits' field in the service setup screen will be ignored.

The Address Group Setup Screen contains the list of host or network addresses in a specific group. Addresses can be added to or removed from the group within this screen. The `Bits' field allows you to specify how many bits must be matched; for example, for a host address you should specify 32 bits, for a class C-style network address you should specify 24 bits, and so on.
