About network interface setup
A primary component of the WatchGuard Firebox setup is the configuration of network interface IP addresses.
When you run the Quick Setup Wizard, the external and trusted interfaces are set up so traffic can flow through
the Firebox. You can use the procedures in this section to change this configuration after you run the Quick
Setup Wizard, or to add other components of your network to the configuration. For example, you can set up
an optional interface for public servers such as a web server.
A firewall physically separates the networks on your Local Area Network (LAN) from those on a Wide Area
Network (WAN) like the Internet. One of the basic functions of a firewall is to move packets from one side on
the firewall to the other. The common name for this is routing. To route packets correctly, the firewall must
know what networks are accessible through each of its interfaces.
