Can I host on one pc and play the game on another pc? Like I cant connect to my game from a different pc it says: "Cant Connect, Problems connecting to BYOND, Firewall blah blah" But Other people can connect and I dont have WIFI problems.
If you're using a router you would normally need to set up a proxy. But if other players can log in that wouldn't be the problem. Could it be some kind of multi-key feature in the src?
How could I figure it out?
Open src, ctrl+F all the <code>Login()</code> procs until you see something under it relative to multikeying.
Sure you can host on one pc and play on the other you just have to set the ip for hosting pc while just play on the other one.

Ps. make sure there isnt any multikey coding that restrict you from doing same ip different account shit
