It basically describes the concept of forwarding connections to a specific local computer system. Usually a computer router, firewall or other hardware device that is managing or controlling traffic is involved in the process and needs to be configured to forward the port. Port forwarding can be a big issue when running P2P applications like uTorrent as a wrongly configured router can reduce or even block the traffic to the local computer running the P2P application.

Port forwarding can be configured in the router or traffic controlling device. It basically consists of telling the router route to send incoming traffic to a specific computer by specifying a port and IP address.

One of easiest ways to check if a port is properly forwarded is to use an online port checker like the one provided by uTorrent. To verify the port forwarding open the following url in your web browser http://www.utorrent.com/testport.php?port=1337 and change the number at the end to the port that you want to forward.

The script will check if the port is forwarded properly:

The above screen is displaying that the port forwarding has been properly configured. It will display that an error has occured. The port forwarding test can be repeated after adjusting the configuration settings.
