Description

This article describes how to obtain the WAN IP from the FortiGate CLI.

Scope

All versions of FortiOS.

Solution

Run the following command in the CLI:

diagnose system wan ip

This will grab the public IP of the default connection from https://api.ipify.org.

If multiple WAN connections are in place and it is necessary to obtain the public IP for a specific one, run the following

diagnose system wan ip <interface_name>

This is useful when the FortiGate is behind the NAT and the public IP of the WAN connection(s) is not known.
