How To Setup And Configure Port Forwarding

How do I setup and configure port forwarding on my router? What is port forwarding? Port forwarding is a procedure that your router uses to direct network data to the right port. Routers and your computer use ports to organize network data. Different sets of data, such as websites, file downloads, and games, are each given port numbers to communicate with each other. By using port forwarding, the router sends the correct data set to the correct computer on the network. For example if your kids wanted to play an online game with there computer you would open up port 5500 and configure the router to send all data to the kids computer, while at the same time you could tell the router to send all remote desktop protocol requests to your computer using port 3389.
