Using Aliases

Aliases provide a simple way to remember host IP addresses, host ranges, and network IP addresses. They function in a similar fashion to email distribution lists--combining addresses and names into easily recognizable groups. Use aliases to quickly build service filter rules. Aliases cannot, however, be used to configure the network itself.

WatchGuard automatically adds six aliases to the basic configuration:

Group	Function
firebox	Addresses assigned to the three Firebox interfaces and any related networks or device aliases
trusted	Any host or network routed through the physical Trusted interface
optional	Any host or network routed through the physical Optional interface
external	Any host or network routed through the physical External interface; in most cases, the Internet
dvcp_nets	Any network behind the DVCP client
dvcp_local_nets	Any network behind the DVCP server

A host alias takes precedence over a Windows NT or RADIUS group with the same name.
