Is rcon possible with port 27015 blocked?

[Terin]

For various reasons, port 27015 is unavailable on my router, so I'm using port 27016 and beyond for my dedicated servers. However, this makes rcon unavailable, since it looks for a connection on the 27015 port. Is there any way to change that port, or can I not use rcon without port 27015?

rcon is using the same port as the gameserver. However it's using TCP and not UDP. You might need to forward or open TCP 27016 on your router too.

Oh yeah, that might be the case for me. I think I forwarded 27015 once as TCP and UDP, but probably did just UDP for 27016. I'll have to check that later, thanks.

No, it looks like the range of ports past 27015 is forwarded for both TCP and UDP. I'm able to connect to the servers just fine, but rcon just refuses to work. Working on ports other than the default is the only time this has happened, which leads me to believe that the rcon port is currently stuck on 27015.

Do a netstat -a and check if the system is listening on TCP 27016

It looks like there's no TCP listening on the range of ports, just UDP. 27015 is listening for TCP for some reason, which is strange.

It looks like I'd need to do something on Linux's end in order to have rcon work. How would I open TCP ports there?

I don't think it's a linux problem. More like maybe a bug on the linux srcds. I'm running my server on windows so I can't help that much more. Which game are you running and what's your startup command line for this server?

[Terin]

I'm running all the SteamPipe games and Garry's Mod, and it exists for all of them. My startup command is currently

screen -A -d -m -S tf2-ds /home/user/Steam/SteamApps/tf/srcds_run -game tf +map koth_nucleus +maxplayers 24 -port 27025

So nothing out of the ordinary there, as far as I can tell.

Jeah...looks fine. All I can say is that on my windows box it works fine with each server using the TCP port for rcon.
