Is there something wrong with this?

My hosting STILL isn't working on the master server.

Your IP address is wrong. You're supposed to use your private IP but that's clearly a public one. Press start and in the search box type cmd (or if you happen to be on Windows XP click run and type it) to open the command prompt. Once there, type IP config and look for IPv4 address. That's the address you type there.

What port forwarding does is direct any information sent to that port to your specific PC, as opposed to any of the other devices in your house. That's why you need your PC's IP.
