Not sure if this even goes in here. I'm having some weird problems with creating a listen server. I need help testing a view things on a map I'm working on so i ask my friends. A couple days ago my friend connects perfectly fine to the server, but my other friend couldn't connect. Next day, that friend who couldn't connect connected fine. Today, i ask him to test again, and he couldn't connect, along with my other friend that i asked. Idk what the hell is going on. I do the same exact thing each time.
Load the map up, type in sv_lan 0, restart the map, give my IP to a friend, he types in connect MYIP, and joins and or doesn't join.
Didn't change anything, and for some reason sometimes they can connect, and sometimes they cant.
