IPSec Win2K server with VPN Terminal services

I am preparing a server for co-location. It is a Win2k server with SQL 2000. All service packs are installed.

What I would like to do is use TS (Admin Mode) through a VPN  connection ONLY and block it to the outside world. VPN & RDP are working now, but the port is open. I have tried to block the port, but even with a VPN connection it will not allow a RDP connection if the port is "blocked"

I have taken a lot of security steps ( MS Baseline Security & SQL C2) to try to enhance security. This is a stand alone server.

There is one network card installed and I have an IPSEC policy to allow 80,443,20/21 in and out. I have blocked all other traffic.
I have tried applying a Permit action to "remote" connections

The answer should contain steps to allow a Terminal Services RDP connection via VPN while blocking port 3389 to external traffic.

Thank you.

This might not be the answer you are looking for, but have you considered using a firewall device and VPN to that rather than the win2k box itself?  Then use TS to connect to the box.  Its usually better to structure it this way, the hardware forewall will be faster and more secure.

Otherwise, let me try to mirror back what you are asking for:
VPN to Win2k box and allow TS to that same box after the vpn connects.  Is this right?

You could assign an additional internal, non-routable IP to the box. (192.168.1.10 for example) and then allow 3389 to that IP, but block it to the public address.  Then with the VPN you should be able to connect to the internal address with TS.

Again, I usually go the other way, with a hardware firewall, but I think the other way should work.
