Difficulty in setting up VPN on Windows Server 2003

Please let me know if there's a better forum for this question. I am trying
to set up VPN on Windows Server 2003. I have a firewall between the cable
modem and the server box and no machines connected to the server.

I installed VPN, but not the router services, and told it to hand out IP
addresses as it likes (no range specified). I created a user group and
placed my account in that user group and then created a Remote Access Policy
that allows that group to access VPN. I configured the LinkSys firewall to
forward ports 1723, 47, 500, 4500, and 50 (both TCP and UDP protocols) to
the server. When I try and VPN into the machine, I get a "computer does
respond" error after it tries to authenticate the username and password.

I wasn't sure about the ports to forward...are the ports correct above? I
tried specifying the protocol on the client box for PPTP (in case the client
was choosing L2TP), but no go. Installed IAS and DHCP to see if that would
help...but nothing has helped. Note that when I installed VPN it asked for
a network connection to the internet, which I gave it, and then it asked for
the network connection to the internal network...but since I have no
internal network I picked an unused network card. It didn't seem to care...

Any ideas? I've read the white papers and I thought I followed the
directions but no luck yet.

Thanks,

Hi,

Instead of opening TCP port 47, you need to configure therouter to allow IP
protocol 47 (GRE). Set the clients to use PPTP.
