I'm trying to connect via VPN to our corporate network using an ADSL connection. My system is Win XP Servicepack 2, and the VPN connection is L2TP-IpSec, I use a SpeedTouch 510 modem.
I can successfully connect and open an ssh-connection (using cygwin) to one of the local servers - but after a short time the connection hangs, e.g. I issue an 'ls' (unix-style) and some lines are returned and than it stops dead. But the VPN connection still lives and I can open up another ssh session - which will die the same way soon after.
As far as I know the MTU size is set correctly by the firewall. I was told that it's not necessary to change settings on my local machine. The VPN setup works for other people - but I'm the only one using ADSL. I'm far from an expert with VPN and I would appreciate any hints to get this running.
Thanks in advance, Stephan
