Hey, I am having a problem with my Gmod 13 server. I set up this server yesterday and I use DarkRP and ULX with it. One problem, I can only see this server in LAN. I tried commands like heartbeat and sv_lan 0 but it never helps. Any help would be VERY appreciated.

I don't think you can see it yourself because YOU'RE the hosting it.
It happens to me. People can join my server, but when I right click and View server Info on them it says "Server not responding" when it's working properly.
I can also not see it on the masterlist, I assume other people can. Maybe get a friend to check for you.
