Omg I just had this wild idea and it fixed my hosting. O_O OK now that you people know how to port forward, I assume you know how to access your router here
1. Now, somewhere, probably under maintenance, there should be a subsection titled "Connected Devices", or something along those lines. Click it.
2. Look for the name of your computer. It will replace space with a hyphen.
3. Once you have found your computer's name, look for the IP address beside your computer's name. E.g. 192.168.0.x
4. REMEMBER THIS NUMBER!
5. Go back to port forwarding, and make the ports 2302, 2303, 8871, and 80 open and where it asks for the server IP, enter the number you remembered. NOT 192.168.0.1, as all that will do is redirect toward your router.
I realize some of you have different routers, but mine just happens to be that way. If you have a different one, go to portforward.com and find your model, and do pretty much the same thing. I think. So yea.
