Topic: VPN reliability

[cliff]

Ive been using the pptp vpn functionality with mixed results. Using win2k clients (ms built in vpn client) in a variable latency environment, the connection sometimes goes "dead", that is it thinks it is connected but will not pass data. when I disconnect and reconnect, it works. Any ideas on how to improve reliability? Is this a server issue or a client issue? The problem seems to be especialy troublesome when wireless networks are involved. Any ideas would be great.

It's neither, it's a protocol issue, and you can't do anything about it. The Internet drops packets from time to time, and wireless is probably more susceptible than most. TCP was designed to handle this. PPTP, OTOH, sucks really badly in the face of lost packets. Designed by Microsoft, OK?
