Hi, my friend experienced a strange problem, when he host, nobody can join or see his server. But I got another case, when I host, all people can see my server and join in, but he cannot see my server in the game list (WTF?)

What did I and he need to do?

did he try hitting the "refresh" button in #AG? (your friend)

if he has a router thats the problem, luckily there is a method to tell the router to open its ports.
