If you are running 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 the 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 the 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 external 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 the internal network. You should be able to connect to
any Internet address.
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.
To set the date and time
For effective scheduling and logging, the FortiGate system date and time must be
accurate. You can either manually set the system date and time or configure the
FortiGate unit to automatically keep its time correct by synchronizing with a Network
Time Protocol (NTP) server.

To use NTP to set the FortiGate date and time
1 Go to System > Config > Time.
2 Select Synchronize with NTP Server to configure the FortiGate unit to use NTP to
automatically set the system time and date.
