is there a way to target specifically which processes have access and such for ports/connections? makes things pretty secure and easy aswell.Ī side follow up question that I hadn't thought about. and even if I need rcon I can easily log into my vps and do things to the server console from there. I have a seperate admin module currently in testing which removes the need for a rcon. as for rcon I won't need to worry about whitelisting an ip or anything. will I run into any sort of issues with this sort of setup in the iptables? I want to ensure all 4 are fully up and running while also being secure aswell. These are all running on the same machine btw with their resources devided out as they need them so they don't interfere with each other. I'm currently running 3 servers on gmod aswell as a teamspeak3 server. (btw a slight bit of background is important here) I've done some stuff with iptables already just getting things exactly right isn't always my strong suit. So if I have 3 instances of srcds_linux open with thier own ports specifically for them this is how I'd block rcon completly correct?
