As the title says, i'm having some problems setting a server on my pc to run some "practice events". Basically, once i start the server, i see it in the LAN section and i can join it. My friend, on different connection, can see the server in the server list but he can't choose a car and after a while it says "unable to contact the server". My brother, on the same connection but different computer, can join without any problem from the LAN section. I've opened the ports 9600 and 8081 both udp and tcp, selected 6 skins because the server has 6 spots. Do you have any idea of what could be the problem?
