Just installed the classic UT from Steam and discovered that LAN gaming doesn’t work. When you try and host a game you get;
Your network configuration may not be compatible with
hosting matches. Please check your router’s manual for
instructions on setting up “Port forwarding” or a “DMZ
server”.
The easiest way around this is to get the Host to write down their IP address. Then they should start a LAN game as normal, ignore the dumb error message. Then the other players start UT open the console (F10) and type; open {Host IP Address}
NB if you the client gets an error complaining that they don’t have Steam Authentication then they should close UT, go to Task Manager and kill any Steam processes and try again.
I checked, it is almost 2016 and we’re having to do this :s
