Good morning,
Is it possible to establish a PPTP connection from a guest running Windows
2000 Professional SP4 to a remote machine running Windows Server 2003 using
user-mode networking?
It appears to me that the problem is that GRE protocol packets are not being
successfully transmitted. I can create a PPTP connection to the VPN server
from the host machine and, using iptraf on the external interface, I see GRE
packets being transmitted. However, when I initiate the connection from the
guest machine, using iptraf, I see the initial connection using TCP to port
1723 on the server but no GRE protocol packets are detected.
Thanks for your help.
Until next time, Colin.

GRE is not supported by user mode networking. Try bridging or VDE.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
