Happens for all games, not just Garry’s Mod. Just that Garry’s Mod is the one I’m trying to host for the most.
Basically, it’s all setup fine with port forwards ETC. People from all over the world can connect, and people in my LAN can also connect. However, two of my friends, both who only live 2 or 3 streets down from me, cannot. They get the “server not responding” error.
Any ideas as to why this might be?
