We installed Ciscos VPN client 3.6 on both XP Pro and w2000 machines. The VPN connection can be established, but drops after 30 seconds to 30 minutes. We are using DSL and seem to have no other Internet or network problems (win2000 server) I added ForcedKeepAlives to the configuration file for the Cisco client. This didn't help. The DSL provider says our line is clean. Any ideas for troubleshooting this?

Actually I'm wondering about the devices in which the clients are coming through, such as modems, Cable Routers etc.?

You may have to list out each device and consider them to determine where the problem lies.

We were experiencing a similar problem at one of our remote sites. After swapping out the modem, the router, and the cable the problem finally turned out to be an intermittant short on the phone line (DSL). Good luck.

If you are access a network remotely, try this to see if it helps. Some keep alives are not very effective and I turn off the keep alive and run an extended ping through the firewall of our network so the firewall knows info is being passed. You can try this: Go to start, run, type in cmd and hit enter. From the command prompt type: ping -t hostname. I send the ping to my Unix box on the intranet which keeps me alive for 12 hours at a time.
