OK, i have opened all the ports on my router and some friends can join my server, but only one can't see my server, why?
You sure it is not your friend who has something wrong on his end ? Provide some more detail.
He is using an ADSL connection with a Port Ethernet Hub and when i create a server everyone can connect, but he can't. I've passed him my ip and he see the adress ip and not my server name. He says me that when he try to connect he see Waiting connection.
Has he disabled any firewalls / virus scanners he may have ?
