VPN support from a LinkSYS BEFWS11 S4 v.2 Router

I can create a VPN connection within my network behind the firewall. I have a W2K Active Directory Domain employing a single internal RRAS server (also W2K). The internet gateway is the LinkSYS router mentioned above. I am trying to see if I can access my network via a VPN connection outside of my internal network. I know that the LinkSYS router is probably not designed for this but I have been able to use it's port forwarding options to gain access with pcANYWHERE and Windows Terminal Services.

From the information I have, I know that PPTP employs port 1723 via TCP and L2TP uses port 1701 over UDP. I have forwarded those port calls to my internal RRAS server so that when I call upon the public IP address of my router with a VPN session, the call should go to the RRAS server and authenticate. I also have the PPTP and IPSec pass through options enabled. However, this fails and I don't find anything in the event logs for a clue.

I am mainly doing this to finish my MCSE so this is not something I would not recommend in practice, but I would like to see if it could make it work as I have described. If the LinkSYS Router will not allow this then I would like to know now instead of wasting any more time.

Thanks for any replys.

There is a small sentence in the user guide that says that if you're using port-forwarding, you must disable DHCP server. Not sure why.
Also, PPTP uses not just 1723, but protocol #47 (GRE) to establish the tunnel. GRE has no concept of ports, so about your only option is to put the server's ip in as the DMZ host.

Setting up the W2K Router as the DMZ host in the LinkSYS worked. I am able to connect remotely without a problem. In fact, I went to my neighborhood Panera Bread which has WI-FI and this is where I am now testing this.

The only thing I have noticed that does not work is access to a DFS share. I can connect to any server share or map a drive, but I can not access the DFS share. Any ideas on resolving this? Also, can you shed any light on the security risks of leaving the W2K router in the DMZ? I am sure there are some.
