My friend is over my house with his computer and we are looking to play some custom zs in LAN. However, when I try to host a LAN lobby or he does I get the error the game session is no longer available when I can clearly see on his screen it is. We both are connected to the same network, we both have legit copies but it won't let us play. I have already downloaded the LAN fix and did the "+set net_port 28960" fix, yet none of these work I am hoping one of you guys has a different fix I am desperate this has been going on for so long I just wanna play some LAN with my friend  .

Thanks, Ziftos
