How to test your VPN solution

If the following tests show that your tunnel is not working, see the How To Note How To Troubleshoot A Virtual Private Network (VPN).

Check the The simplest way to test a tunnel is to ping from one LAN to the other.

LANs are

reachable From a PC attached to one peer, ping a PC attached to the other peer. For example, you can test the VPN between branch office 1 and headquarters by pinging any PC in the branch office 1 LAN from any PC in the headquarters LAN. If a PC in the branch office 1 LAN has an address of 192.168.141.1, that means using the following command at the command prompt on a PC at headquarters:

ping 192.168.141.1

If a Microsoft Windows PC’s IP address was assigned dynamically, you can find out what it is by using the following command at the command prompt:

ipconfig

Check traffic To tell if traffic passes through the tunnel, perform a traceroute from one LAN to the goes through other—so from a PC attached to one peer, perform a traceroute to a PC attached to the

the VPN other peer. For example, if a PC in the branch office 1 LAN has an address of 192.168.141.1, that means using the following command at the command prompt on a (Windows) PC at headquarters:

tracert 192.168.141.1

If traffic goes through the tunnel, the traceroute may display IP addresses from one or both peers’ private networks and public interfaces. If it shows other public IP addresses, then traffic is not passing through the tunnel.
