Connecting the FortiGate unit to your networks

FortiGate-100 Installation and Configuration Guide
When you have completed the initial configuration, you can connect the FortiGate unit
between your internal network and the Internet.
There are three 10/100Base-TX connectors on the FortiGate-100:
• Internal for connecting to your internal network
• External for connecting to the Internet
• DMZ for connecting to a DMZ network
Note: You can also connect both the external and DMZ interfaces to different Internet
connections to provide a redundant connection to the Internet. See
Multiple connections to the Internet" on page
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.
