Testing a VPN

To confirm that a VPN between two networks has been configured correctly, use the ping command from one internal network to connect to a computer on the other internal network. The IPSec VPN tunnel starts automatically when the first data packet destined for the VPN is intercepted by the FortiGate unit.

To confirm that a VPN between a network and one or more clients has been configured correctly, start a VPN client and use the ping command to connect to a computer on the internal network. The VPN tunnel initializes automatically when the client makes a connection attempt. You can start the tunnel and test it at the same time by pinging from the client to an address on the internal network.
