Okay, i got two systems running Windows XP SP3, ESET Smart Security 3.0 Business Edition. I have both systems on a Linksys router connected to a Cable modem which is besides the point. Anyhow, i want to setup either system to see each other through lan games, i.e. Call of duty, Call of Duty World at war, Far cry 2. So far i just disable ESET Firewall to get them to see each other. I'm using Automatic Mode on both systems, and pretty much got most of the security checked except the Runtime Packers and Advance Heuristics in the Real-Time file system protection setup. I have set on both systems the Strict Protection setting in the Trusted Zone. I also have on both systems unchecked the allowed services as well. I can only ping from either system only if the Allow Sharing is selected instead of Strict Protection. Even when i have the ESET Firewall disabled i'm still not able to see either system in Far Cry 2. I just need someone to send me in the right direction, and possible ports for either games, thank you.
