title: How to setup CentOS port forwarding on a VPS?
body: <p>I bought a VPS for my game since I was developing and hosting it on my own network. I would simple do port forwarding between my router and my machine, making the config on the router's page. Now, I don't know how to do the same thing on the VPS (SSH). I read something about <code>iptables</code> but Idk if it is what I'm searching for. I just want to open an UDP port. There was Apache running fine and I stopped it. What commands should I use?</p>
