Yah.. most should disable the c mags.
We've been running a server and haven't seen much in the way of net problems. We do co-op mostly with 40 enemy.
It did take an act of congress to get the server up behind a win2k shared internet connection. Gotta love absolutely zero documentation on port forwarding for that one. I also love that they expect you to forward port 80 for this game. Bwahahaha. I think I'll stick to IP connections.
