You can configure primary and secondary DNS server addresses, or you can
configure the FortiGate unit to obtain DNS server addresses automatically. To obtain
addresses automatically, at least one interface must use the DHCP or PPPoE
addressing mode. See
“DHCP” on page 50 . See “PPPoE” on page 51 .
If you enable DNS Forwarding on an interface, hosts on the attached network can use
the interface IP address as their DNS server. DNS requests sent to the interface are
forwarded to the DNS server addresses you configured or that the FortiGate unit
obtained automatically.
