Hey guys, me and my brother have been really excited about the LAN servers in 1.3, because we will finally get to play Minecraft together. But, as we found out today, we can't connect to a LAN server. We've opened a world to LAN, but it won't show up on the multiplayer list. We've also tried to directly connect with the IP but it doesn't work. I fear that our problem is that we have the same IP, but I don't know if that matters.
Can anyone help?
