FortiGate-200 Installation Guide
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 External interface to the internal or
LAN connection of your DSL or cable modem.
3 Optionally connect the DMZ interface 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.
