Me and my friend have garry's mod, but neither of us know how to set up a server. We try hamachi but it doesn't work! I try to host, and she tries to host but it doesn't work! But this isn't the only game we use hamachi with. We use it for Star Wars: Battlefront II (the one from 2005.) Minecraft, and Minecraft: Windows 10 editon. All work fine. Please and thank you.
P.S. In case you need to know, my friend has a slow connection. But we connect just fine.
