I was all psyched yesterday when my server was at last up and running. All ports open, server cfg in place, and it finally showed up on the Master list, I checked it on one of my computers and connected to it normally (I added my external IP to my favorites) Later some friends were over and I asked my friend to join. He typed in my external IP to his favorites as well but he timed out, He also did not see it in the master list (but I still did) the only way he ended up joining was by going through it in LAN not Internet. Any ideas?

Nevermind, The problem was so stupid I dont even want to talk about it, its fixed though
