So I've been messing around in UDK and managed to launch a dedicated server console. I can join using my public IP Address although if my friend tries to join using "open HOSTIP" he gets stuck in the loading screen. I have the ports open on my side, does he need to open them too or anything? or am I doing something wrong.
Also I am using this to launch the UDK as a server; 'UDK.exe server DM-Test?game=UTGame.UTTeamGame?listen=true' If anyone has experience in this any help is appreciated.
