How does Kali work?
A Kali makes itself look like a normal IPX (LAN) network driver. Your LAN games operate normally, but instead of looking for opponents on a LAN, it looks for opponents across the Internet. For most games this trick works great. The only problems occur when the game expects the connection to be faster or needs to send more data than a typical modem connection can provide. The result is that you might be limited in the number of players that can be in the same game. Some games are affected more than others so you cannot expect the same performance for all of your games.
