I'm using Windows Server 2008. Currently I have IIS installed and I'm hosting a few web sites. What I'd like to know is if I can install a VPN server on this same machine so that I can have other people, VPN in and we can play LAN games. Is this going to be possible? I only have one NIC on this machine. I already installed the VPN using a guide I found online but I don't know how to set it up so the clients can just put in a username/password to connect.
