This guide will show you how to enable and configure port forwarding on the D-Link 704P Cable/DSL Residential Gateway.  I assume that you already have the router up and running before you try to open up port forwarding.

You should see the following login screen.


Type in the password to the router and click "Login". You'll see the "Device Information" page.

Scroll to the bottom of the screen and click on the "Save" button.

Now click on the "Reboot" button.  A dialog box will ask "Reboot right now?".  Click "OK".


As the router restarts you'll see this message:


Then the router will display the Device Information page again.  You can click "Log Out".
