I have a small LAN set up at my house. The LAN consists of my computer and my kid's computer. We share the internet via a 4 port Linksys router. Can both the kid's and myself play the same multiplayer game such as Team Fortress or CS at the same time over the internet. I have a feeling that we can't because we are sharing one IP address but I wasn't sure. I figured I'd ask the question before I go out and buy two games. Thanks for the advice!
