Public bug reported:
I have an Ubuntu desktop machine at home and also an Ubuntu 7.10 desktop machine at work.
I can connect to work from home using PPTP VPN (to a Windows 2003
Server). The VPN connection works fine - I can browse samba shares and
use sftp. I can SSH in to my desktop machine and use the command line
without any issues.
However, as soon as I attempt to launch a program which uses X11
forwarding the entire VPN connection immediately stops working, I can no
longer ping any machines at work.
I can connect to the machine with the X11 forwarding option without
issue (ssh user at WorkMachine -X), the problem occurs when I run a program
Tested (as the client) using Ubuntu 7.10 and Hardy beta - same problem happens on both.
However, X11 forwarding from my Ubuntu desktop at work is fine if I connect to work from home using Windows XP with Putty & Xming.
Not sure if the problem is in SSH, or VPN.
