How does ZoneAlarm affect gaming?
Attending a LAN party or playing a game that is connected online? Although standalone games rarely create issues with ZoneAlarm, the new generation of connected games may attempt to open lines of communications with other PCs on your LAN or on the Internet. Since these connections are similar to the communication that Trojan Horses or other malware often attempt, they may not be allowed by ZoneAlarm. If you’re connected to a LAN where you know the other players, you can add that LAN to your “Trusted Zone” and use a lower level of security. Alternately, review the user manual for your game and determine what ports need to be opened. Then, use the “Expert Rules” in paid versions of ZoneAlarm to allow the required communication.
