I cant connect to my friend

Hello facepunch.
So , I wanna play Gmod with my friend . He creates server and bla bla bla .
So , im connecting to him , and ALWAYS get timed out.

Forward ports

Damn , week ago all worked fine

Maybe its because you have no friends?

I have the same problem, and I do know that you forward ports to fix it, but can I get a nice, simple, non-tech support language walkthrough on how to forward them? Surprisingly, I can figure out LUA and Hammer, but I don’t understand much about any DCIP 22.763 port that you have to plug into slot J27 or something. Make the correct assumption I have no knowlege about this stuff.
