Configuring an interface for PPPoE
Use the following procedure to configure any FortiGate interface to use PPPoE.
If you configure the interface to use PPPoE, the FortiGate unit automatically
broadcasts a PPPoE request. You can disable connect to server if you are configuring
the FortiGate unit offline and you do not want the FortiGate unit to send the PPPoE
request.
By default, the FortiGate unit also retrieves a default gateway IP address and DNS
server IP addresses from the PPPoE server. You can disable the option Retrieve
default gateway and DNS from server if you do not want the PPPoE server to
configure these FortiGate settings.
