REMOTE VIEWING OF HOME IP CAMERA

HOW DO I SET UP THE ROUTER SO THAT I CAN SEND MY HOME IP CAMERA VIDEO TO THE INTERNET AND MY IPHONE SO I CAN VIEW THE CAMERA REMOTELY ?  I HAVE SET A LOCAL STATIC IP FOR THE CAMERA AND I AM ABLE TO VIEW THE CAMERA ON MY LOCAL NETWORK.  WHAT SETTINGS DO I NEED FOR MY ROUTER TO FORWARD THE VIDEO FEED.  I AM TRYING TO DO THIS WITHOUT PAYING A SERVICE.  

I HAVE DSL 3

THANKS IN ADVANCE.
