If Your Isp Uses Dhcp - Watchguard Firebox X15 User Manual

Configure external interfaces
You must configure your external network manually if you do not use the Network Setup Wizard.
When you configure the external network, set the method your Internet service provider (ISP) uses to give you
an IP address for your Firebox. If you do not know the method, get the information from your ISP or corporate
network administrator. For information about IP addressing methods, see
You can also configure your primary external interface as a wireless interface.

If your ISP uses DHCP

In the default configuration, the Firebox X Edge e-Series gets its external address information through DHCP.
If your ISP uses DHCP, your Edge gets a new external IP address when it starts and connects to the ISP network.
