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.
