I've had many problems over the years configuring a direct TCP/IP setup for 1 VS 1 LAN gaming. Mostly due to incorrect addresses or antivirus blocking. Still i've managed to resolve the problems. I am using the standart IP setup: 192.168.2.1 for PC1 and 192.168.2.2 for PC2. First question: Does the subnet mask and default gateway matter? I just leave the subnet mask 255.255.0.0 and the default gateway i leave empty. Or should i not? Second question: I have a dual RJ45 motherboard. One is connected to the internet, the other to the LAN. But if LAN is enabled between the 2 computers, my internet connection is lost. How to resolve that? Third question: Since i have dual LAN motherboard, could i host a LAN sever for 2 other computers? So that 3 people could play in one server?
