How do I set-up Port Forwarding on my Motorola Cable Modem Gateway?

Port Forwarding opens ports to deliver traffic from the Internet directly to devices like game consoles, security cameras, web servers, etc. Ordinarily, the router’s firewall would block this traffic.

What is needed:
The IP address of the client device (i.e. your PC, gaming console, security camera)
The port number(s) and the protocol (TCP, UDP, or both)

Open up a web browser (i.e. Internet Explorer, Firefox, Chrome, Safari, etc).  Type into the address box and press Enter.  You will be directed to a Login page.

Type admin in the username box and motorola in the password box.Click on Advanced on the top right hand corner.
