"Virtual LAN Gaming"

Hi all!
I've been wondering about how/if a VPN server can be used to play LAN-only multiplayer games over the internet..?

The scenario I'm thinking about is this:
1. I want to use a W2K VPN server that allows incoming VPN connections to hand out private ip addresses to clients logging in.
2. On another computer on my LAN I set up a multiplayer game, and clients connected through the VPN should be able to join this, as they are "virtually" on the same LAN as I am.

I've tried the basic PPTP setup, and made the connection, however, the game (Microprose GP3) is unable to locate the multiplayer game. I have no idea which ports/protocols this game (or others) use for their connections.

I was advised to try L2TP as PPTP has issues with portforwarding, but I got stuck on digital certificates needed for L2TP.

Anyone got this working who could provide me some info??

i THINK (not sure, don't really remember) that i used to VPN into my previous company and play Quake 3 on the local company lan.  

no idea what vpn setup to use or anything, just fairly certain that it could be done.

there is probably a tutorial in ms knowledge base for vpn on 2k, i know theres one for xp.

Setting up VPN on W2K is the least of my worries, I'm looking for a way of "tricking" LAN-only multiplayer-games into accepting a VPN-designated private ip-address as a LAN-address and thus allowing a connection between one or more gaming-clients via a VPN server. If the problem lies in overhead, in port-forwarding or other limitations, I'd like to know. Also, if setting up L2TP as a VPN protocol is the way to go, some specific pointers as to how this is done would be appreciated.

I dont know if this is an appropriate solution for anyone here, but a friend and I setup 2 Linksys BEFSX41 VPN routers and established a secure IPSec tunnel between our LANs.  We were able to host games such as UT, Diablo 2, Nascar 2002, Sports Car GT, Monster Truck Madness 2 and connect from both LANs using each others internal LAN IPs.  No port forwarding or DMZ was necessary, gameplay was fine and the VPN setup took 5 minutes.

I can't see how any of these comments answer my question, and I was hoping that the recent W2k3 hotfix which fixes NAT traversal issues with VPN connections could be of assistance, but I guess this thread now is closed...?
