How to Configure an xDSL WAN Connection with an Internal DSL Modem in Bridge Mode

In Bridge Mode, your firewall is connected to your ISP through the WAN1 interface of the DSL modem. The firewall initiates the xDSL connection. The public IP address is set via DHCP on the ppp1 interface.

Step 1. (optional) Change IP of Built-In DSL Modem
