FortiGate-400 Installation and Configuration Guide
When you have completed the initial configuration, you can connect the FortiGate unit
between your internal network and the Internet.
The FortiGate-400 has four 10/100Base-TX connectors that can be connected to up
to four different networks. You can connect them in any configuration. When you first
power on the FortiGate-400, the interfaces and zones are configured for the following
connections:
• interface 1 to connect to your internal network,
• interface 2 to connect to your public switch or router and the Internet,
• interface 3 to connect to a DMZ network,
• interface 4/HA to connect to another FortiGate-400 for high availability (see
availability" on page
Note: You can also create redundant connections to the internet by connecting two interfaces
to separate Internet connections. For example, you could connect interface 2 and 3 to different
Internet connections, each provided by a different service provider. See
example: Multiple connections to the Internet" on page
To connect the FortiGate unit running in NAT/Route mode:
1 Connect interface 1 to the hub or switch connected to your internal network.
2 Connect interface 2 to the public switch or router provided by your Internet Service
Provider.
3 Optionally connect interface 3 to your DMZ network.
You can use a DMZ network to provide access from the Internet to a web server or
other server without installing the servers on your internal network.
4 Optionally connect the 4/HA interface to a fourth network (not shown in
Connecting the FortiGate unit to your networks
