I am running a Windows 2000 network with RRAS and IAS, if i turn off the
WinXP firewall on the workstation trying to connect I can connect to the
VPN, if I turn on the Firewall I cannot...? Any Ideas why this would happen?

Thanks
Gavin...
 
The actual VPN encrypted data travels through the Internet as IP packets
with special headers. For PPTP this is GRE (IP protocol 47). If a firewall
anywhere in the path blocks GRE, the VPN connection fails.
