Figure 6: FortiGate-60 NAT/Route mode connections
If you are operating the FortiGate unit in NAT/Route mode, your networks must be
configured to route all Internet traffic to the IP address of the FortiGate interface to
which they are connected. For your internal network, change the default gateway
address of all computers and routers connected directly to your internal network to the
IP address of the FortiGate internal interface. For your DMZ network, change the
default gateway address of all computers and routers connected directly to your DMZ
network to the IP address of the FortiGate DMZ interface. For the external network,
route all packets to the FortiGate WAN1 or WAN 2 interface.
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 your internal network. You should be able to connect
to any Internet address.
