Help Port Forwarding

[Jeffer]

Typing the IP number in the address bar doesnt work so I'm trying to do this with the default gateway. I opened everything up and typed IPconfig. The next step says... Several numbers will appear.
The one next to "Default Gateway" is the number you enter in step 1A of the port forwarding tutorial.

Do I enter this into the black box or what? I don't know what to type to edit the IP number. Please help me on what to do in this step.

Type it in the URL box, otherwise known as the Address Bar.

Type it in the URL box, otherwise known as the Address Bar.

It didnt show up though. Am I supposed to type it while the black box is open or something?
