Nobody can join my gmod server (port forwarding issue)

[HexicDragon]

I know how to port forward, I've done it and it worked just fine with my minecraft server and stuff.

I'm creating a gmod server, and i can go on it, but other people can't connect. it's definitely a port forwarding issue, but i'm trying to figure out how to fix it.

I've read through this thread, http://forums.srcds.com/viewtopic/15755, which seems pretty similar to the problem i have, but id on't really understand how they fixed it.

I have both 27015 and 27005 port forwarded on TCP/UDP, but when i go on a port checker website it says the port is not open.

If anyone could help me that would be great

i have the same problem, people can connect for like the forst 60 seconds then it says server not responding.
maybe there's a timeout setting we dont know about?
