Troubleshooting

To start troubleshooting a VPN connection, break the issue into zones. Start with

the physical connection (Zone 1). Verify that you have a green status and link

light. Build up to Zone 2. Verify that local communication exists to the ExtendNet

VPN by pinging from a local workstation, such as ping <local IP address>.

Ensure that a workstation can communicate with the ExtendNet VPN using the

InterprEYES utility to check the ExtendNet VPN’s current IP address, subnet

mask, and default gateway. Another good test is to see if a client workstation can

initiate a VPN session locally utilizing Microsoft’s VPN adapter (DUN on

Windows 95 or 98 and a RAS connection in Windows NT). In Zone 3, verify that

communication exists with the Internet. Ping a domain name by entering the

following (or some other domain name) at a command line: ping

www.extendedsystems.com.

Zone 4 is the most common cause of issues. By default, a router or firewall is

configured to deny all traffic from the Internet. This means a remote user trying to

connect to the ExtendNet VPN will never reach the ExtendNet VPN server (in

Zone 1) because the packets will be refused by the firewall/router at Zone 4.

Check your forwarding rules for the firewall/router to make sure these packet

types are allowed through. If remote clients are getting errors connecting to the

ExtendNet VPN (specifically error 650 or 629) but clients in Zone 2 can reach the

VPN, it is most likely due to the firewall. In Zone 5, verify the client DUN is
