Veiwing the routers settings in the web browser

Is the pc you are using connected wirelessly? Only computers connected with a cable are allowed to access the configuration page.

If you have a computer connected to it (possibly wireless) find out the ip address by opening command prompt and typing ipconfig . then there should be something labeled default gateway. Copy and paste the default gateway into your browser and hit enter. It should ak you for a username and password, type in the on that you set it up with. Now, you need to find out the IP address of the xbox, and then navigate through the router config and find where to forward the port. From there it should be pretty self explanator. Hope it works!
