Well, my young cousin really likes minecraft. He comes over and spends time with me every now and then. When he does, we usually play minecraft, as it is one of the few games I actually like. Anyway, he wanted his friend to play on the world we created. I don't want him on the global multiplayer server, but a custom one I am fine with.
I set up the minecraft server, and it should work, expect for one little thing. The firewall.
I have a few computers in my network, I have an AT&T 2Wire box. The computer I am running the server on is my Mac. Now, I could just disable the firewall for the few hours we play, but I really would prefer to not do that. Instead, is it possible for me to take the IP Address of his friend's computer, and allow that address to bypass my firewall?
If you have another idea, feel free to share it.
