Connecting the FortiGate unit to the network(s)
When you have completed the initial configuration, you can connect the FortiGate
unit between your internal network and the Internet.
The following network connections are available on the FortiGate unit:
• Internal for connecting to your internal network
• WAN1 for connecting to the Internet
• WLAN is the interface to the wireless LAN on the FortiWiFi models
• DMZ is the interface to the DMZ network
To connect the FortiGate unit
1 Connect the Internal interface to the hub or switch connected to your internal
network.
2 Connect the External interface to the Internet.
Connect to the public switch or router provided by your Internet Service Provider.
If you are a DSL or cable subscriber, connect the WAN1 interface to the internal or
LAN connection of your DSL or cable modem.

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.
