I've never been able to host and I've never been able to fix it, but what I do know is that I have to allow port 6112-6119 TCP and UDP
out and in. Does anyone know how to manually do this without having to buy a $30 program online? I've check Tech Support but it's entirely offline now, and the people you need to call and/or email do nothing but give me a number for a support box on the forums. Even then, that does nothing for me.

Seriously, learn to google.

You would just go to your router page and place those ports to your ip
Most routers you do not really need to set up a static ip.
(For newer linksys routers you will need to set up a static ip or it will not work.)

For the portforward.com website the skip the advertisement button is on the top right.
(He probably google it and did not see the skip)

I tried that guide. Didn't fully understand it.. Also that program costs $30, which is what i was talking about.

Don't use the program then. You asked for manual anyway.
That site is the best site to tell you how to port forward. It has detailed step-by-step descriptions for pretty much any router. If you don't understand that one you won't understand any other.

What is it you don't understand? Try to follow the steps just as they tell you. Heck they even have screenshots.

Oh and btw. you only need ports 6112 TCP and UDP.
6113+ are not needed. That's for WC3.

I too spent a great deal of time trying to forwards my ports without installing a program. Tell me what operating system you're running and what firewall you're using and I could tell you how to open your ports. I have good knowledge manually opening the Windows 7 ports using the Windows Firewall and it's pretty much the same as Windows Vista. On Windows XP is much easier, since on Windows 7 it's well hidden so that people don't screw around.

iirc, port forwarding has to do with your router and firewall, and nothing really to do with your OS.

He needs the OS for the firewall.

Try this program. I haven't tried it, but it is free:

Good point guys.
Marine do you need help opening ports of your software firewall or on your router?
In any case the site I linked to offers pretty good guides for software firewalls too.

I don't see any open source router/firewall systems in that list. Not that I really care, since I don't need instructions on how to forward ports. I suppose it would be useful for someone who has one but doesn't know how to forward ports on it, though.
