Question : Configuring Vigor 2600 for VPN

Hi Guys

Im trying to setup a VPN connection to our office. We have a vigor 2600 bt broadband router which is connected to ISA 2004 server and ISA is connected to our network.

I've setup a VPN connection on ISA and configured it properly, so if i connect to ISA's external address from DMZ it works fine, but if connect from the Internet it just hangs at "verifying Username and Password" and then stops. Im using PPTP.

All the articles i've read are saying i need to forward the TCP port 1723 and IP protocol 47 (GRE) to the ISA's external address. I've opened up the TCP 1723 port on the vigor but i can find IP 47 any where on the Vigor. I've tried TCP 47 and UDP 47. but they dont seem to work.

Any ideas on why it only gets as far as "Verifying Username and password" and how i can forward the IP 47 port to ISA if thats what the problem is?

Thanks for your help.

Sho
