It would seem that noone can connect to my server and, before you ask, yes I have looked up multiple guides on port forwarding for garry's mod, I have tried sv_lan 0, nothing seems to work. I currently have the folowing ports forwarded:
TCP 27020-27039
UDP 1200
TCP 27000-27015
UDP 27015
UDP 27020
What am I doing wrong? Because I am totally sure that it is something obvious that I should shoot myself for missing.
