Interface
System Network
Override internal DNS Enable Override internal DNS to use the DNS addresses retrieved
from the DHCP server instead of the DNS server IP addresses on
the DNS page.
On models numbered 100 and lower, you should also enable
Obtain DNS server address automatically in System > Network >
Options. See “DNS Servers” on page 100.
Connect to server Enable Connect to Server so that the interface automatically
attempts to connect to a DHCP server. Disable this option if you
are configuring the interface offline.
Configuring an interface for PPPoE or PPPoA
If you configure the interface to use PPPoE or PPPoA, the FortiGate unit
automatically broadcasts a PPPoE or PPPoA 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 or PPPoA request.
FortiGate units support many of the PPPoE RFC features (RFC 2516) including
unnumbered IPs, initial discovery timeout and PPPoE Active Discovery Terminate
(PADT).
PPPoA is only available on FortiGate models that support ADSL.
Go to System > Network > Interface. Select Create New or select the Edit icon
of an existing interface. In the Addressing mode section, select PPPoE or PPPoA.
