I tried googling it and got linked to a thread here.
It was by Jorici and I prettymuch have the same problem:
Alright, before anyone asks, I CAN host at my mother's house, I did the exact same thing to host a gmod server there as I did here, only one difference, I cannot at my dad's house. It's weird because I can host other games.
Things I can host:
-Minecraft
-SS13
-Swat 4
Things I cannot host:
-Source games (Tf2, gmod...)
-Blockland
I port forwarded properly, (port 27015), and I THINK I am using the right IP. Not sure, but when I type in ipconfig in the command console, the IPv4 address is under the "Wireless LAN adapter Wireless Network Connection 2" tab, and I do not know if that is correct or not. I don't know what I am doing wrong, or if I am doing anything wrong.
