Garrysmod incoming ports

Is there any specific ports that SRCDS/hl2.exe uses for incoming connections? I need to block them at the firewall level.

what would be the point in having a source dedicated server running if you wanted to block all incoming srcds traffic?

is there anything specific you are trying to do?

No, we want to limit it to the specific ports SRCDS uses, and block everything else.
It would stop many strange exploit attacks.

ohh I see

just be careful if you are doing that with a remote dedicated server; you don’t want to accidently block remote access to it when setting up your firewall rules or block connections to any other services you are hosting like a web server etc

anyway you just need to forward the tcp/udp port that is binded to your srcds server
