get system interface
The CLI lists the IP address, netmask, and other settings for each of the FortiGate
interfaces.
To configure DNS server settings
• Set the primary and secondary DNS server IP addresses. Enter
config system dns
set primary <address_ip>
set secondary <address_ip>
end
Example
config system dns
set primary 293.44.75.21
set secondary 293.44.75.22
end
To add a default route
Add a default route to configure where the FortiGate-5000 module sends traffic that
should be sent to an external network (usually the Internet). Adding the default route
also defines which interface is connected to an external network. The default route is
not required if the interface connected to the external network is configured using
DHCP or PPPoE.
