Installing a FortiGate in NAT mode

In this example, you connect and configure a new FortiGate in NAT mode, to securely connect a private network to the Internet.

In NAT mode, you install a FortiGate as a gateway, or router, between two networks. Typically, you set the FortiGate up between a private network and the Internet, which allows the FortiGate to hide the IP addresses of the private network using NAT.

NAT mode is the most commonly used operating mode for a FortiGate.
