Testing the tunnel
The simplest way to tell if traffic is passing through the tunnel is to perform a traceroute from
the Windows 2000 client to a PC in the router’s LAN. To do this, use the following command at
the command prompt on the Windows 2000 client:
tracert <ip-address>
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.
Checking the connection from the Windows client
To check your connection details, right-click on your connection icon (e.g. Virtual Private
Connection to Head Office) in the Network Connections folder, or on your desktop.
Click Status. Then click the Details tab to check your connection information, as shown in the
following figure.
Troubleshooting
If your tunnel is not working, see the How To Note How To Troubleshoot A Virtual Private Network
(VPN).
This How To Note has detailed information about testing and troubleshooting VPNs on the
router.
