System network

System network settings control how the FortiGate unit connects to and interacts with
your network. Basic network settings start with configuring FortiGate interfaces to
connect to your network and configuring the FortiGate DNS settings.

More advanced network settings include adding VLAN subinterfaces and zones to the
FortiGate network configuration.
