Routers use NAT to figure out where internet traffic should be directed: http://www.geekstogo...AT-t170913.html.
Port forwarding bypasses NAT and says that everything coming in on a certain port will go to an address specified.
For example:
You are hosting a web server. Someone types your IP address into their web browser. Because your computer did not establish the connection when that HTTP traffic hits your router it will not know what to do with it. So you set up port forwarding that forwards port 80 to your computer. Now incoming web traffic will make its way to your server.
