Configuring an interface for PPPoE
If you configure the interface to use PPPoE, the FortiGate unit automatically broadcasts a
PPPoErequest. When configuring the FortiGate unit offline and you do not want the
FortiGate unit to send the PPPoE request, do not enable Connect to Server.
FortiGate units support many PPPoE RFC features (RFC 2516) including unnumbered
IPs, initial discovery timeout and PPPoE Active Discovery Terminate (PADT).
To configure an interface for PPPoE
1 Go to System > Network > Interface .
2 Select Create New or select the Edit icon of an existing interface.
3 In the Addressing mode section, select PPPoE .

On low end models, this is enabled by default.
When VDOMs are enabled, you can override the internal DNS only on
the management VDOM.
Connect to Server Enable so that the interface automatically attempts to connect to a DHCP
server. Disable this option if you are configuring the interface offline.
