Hello I must summarize what your problem is: * You can connect the two peers. * You can transmit pacakges. * It may break and do not reconnect because a call manager is still there.
Have you tried to remove the firewall rules, so they are not a problem? I assume that you have read: http://pptpclient.sourceforge.net/howto-diagnosis.phtml On Mon, Apr 11, 2005 at 08:57:49PM +0200, Robert Kloibhofer wrote: > Hi > and thanks for your quick respond. > > > > After stopping pppd, ps -aux shows a process called > > > "pptp: call manager for 10.0.0.138" > > > Sending SIGKILL (kill -9 ; SIGTERM doesn't do anything) to this process, > > > and reconnecting works fine. > > > > If kill -9 do not work, this os not a problem in pptp-linux.

Ahh that is a different thing. :) If this is the case I think the call manager here is the process that try to connect.
