Configuring the networks
If you are running the FortiGate unit in NAT/Route mode, the networks must be
configured to route all Internet traffic to the IP address of the FortiGate interface to
which they are connected.
If you are using the FortiGate unit as the DHCP server for your internal network,
configure the computers on your internal network for DHCP.
Make sure that the connected FortiGate unit is functioning properly by connecting to
the Internet from a computer on the internal network. You should be able to connect to
any Internet address.
Next steps
You can use the following information to configure FortiGate system time, to register
the FortiGate unit, and to configure antivirus and attack definition updates.
Refer to the FortiGate Administration Guide for complete information on configuring,
monitoring, and maintaining the FortiGate unit.
