Cant Host a Server

I know this is FAR from a new problem, but I figure by now you guys must be pro’s at troubeshooting this.

Alright, I have set up a static IP, forwarded my ports to 27015 or whatever, and have it for both TCP DCP or whatever. And still no dice.

I tried going into console and typing “sv_lan 0” (without quotes of course) and having the client type "connect my.ip.add.ress:27015 (except it was actually my IP)

AND STILL NO DICE.

Help me facepunch, you my only hope.

Apparently, you didn’t port fowrard correctly. That’s all I can say.
