Trying to figure out how to host Garry's Mod games (not dedicated servwer)

I have tried many times to get it to work, but nothing seems to be working. I go to “Create Multiplayer”, select gametype, and start the game. The server appears, but it won’t respond for anyone. I have followed the instructions on “”, and have all the ports I need opened. It just won’t work. I have also put “sv_lan 0” and “heartbeat”, but they don’t help.

I came here seeking help because you guys seem to know what you’re talking about. Anyone have any advice on what to do? I would really appreciate it if you did.

Port forward lacks all needed ports.

First, as a work around, tell your friends to connect by typing
connect youripaddress
in console.

Next, there is another port that’s the master server list, but I don’t remember it. All I know is I have these forwarded:

27000-27015 to my ip udp/tcp
and some other port at a really low range for the friends network. Use search and find that one.

I have opened these ports:
TCP 27014-27050
UDP 27000-27030
TCP 4380
UDP 1200

I have a 2Wire2701HG-B Router.

And, I might just try that suggestion. I hope I can figure this thing out.

Try opening Tcp 27015 and udp 27015

I have the same problem

He just did port forward 27015.
