I am trying to establish a VPN server using a Windows 2000
Server box which is connected to the net via a NetGear
DG834 Router/Modem.

I have installed and configured the Routing and Remote
Access service, enabled access for the account I am using
in Active Directory, and created appropriate Firewall
rules to open the 1732 and 500 VPN ports for PPTP
communication. I have even tried turning off the Firewall
completely and following problem still occurs.

When I try to connect using a Win 2000 Pro client which is
using a dial-up connection, I get an Error message
721 "The remote computer is not responding".

There is nothing glaringly obvious in the access profiles
or authentication settings, I have tried using no
encryption and even no authentication and same problem
still occurs.

Any help on this would be greatly appreciated!

Thanks,
 
You need to open TCP port 1723 (NOT 1732) and allow IP Protocol 47 (GRE).
You do not need TCP or UDP 500 open for PPTP.
