I was reading around portforwarding.com and a in the readme/walkthrough it said that game servers (or any type of server for that matter) require certain ports. Where on earth do you find that information? Whenever I tried to set up a server along with setting up ports, I never found that information in any readme or tutorial online for that game (except just recently when I found portforwarding.com). And the only time I got information such as that was Steam server setups, but it never went into any detail on how they aquired the ports, just that it was the right ports. On port forwarding for certain games are, I would like to know how portforwarding.com aquired those 'right' ports in the first place?

Well, there are several ways of doing this.

First of all you can just run the server, and see what ports are being used by firing up WireShark and taking a look at the packets.

Secondly, you can look at tutorials on the internet - I know for a fact that there are plenty of Steam server tutorials which state what ports are used. If you search my website for "CS:Source," you'll find my own tutorial - the port list is on there too

HTH,

O no, I never said that there wasn't a Steam tutorial that didn't tell you what ports to use. I just never found that told you how you find out. Thank you I'll look into WireShark.

I started up MOHAA dedicated server and I saw this line... is this the port number I was looking for or no?

Opening IP socket: localhost:12203

Yes, that is the port number you were looking for: 12203

I know BF2 (Battlefield 2) displays it's port whenever you search for games in MP or even SP. When you start an SP game, your IP and port are displayed. Very handy for your LAN, since other people can simply plug into the same switch and use their game to connect to each other. I think you can do co-op and MP with that easily, not to mention playing in a huge LAN...
