What Is Port Forwarding?

Port forwarding is the redirecting of computer signals to follow fixed electronic paths into your computer. If the computer signal can find its way into your computer a few milliseconds rapidly, it will add up to be dramatic or Theatrical speed increases for your downloading or your online games.

65,536 Microscopic Paths to Choose From 

That Wireless network adapter or pen-thin network cable at the back of your computer contains 65,536 microscopic pathways inside it. Your network cable is the same as a big highway, except your network cable has 65,536 lanes, and there is a toll booth on each lane. We know each lane as a 'port'.

Your internet signal contains millions of tiny small cars that travel on these 65,536 lanes. We know these small cars as "transfer packets". Transfer packets can travel very speedily (up to thousands of kilometers per second), but they do observe a stop-and-go set of rules, where they need to stop at each important network intersection as if it is a border crossing between countries. At each intersection, the packet must do three things:
  • Find an open port
  • Pass the identification test that will allow it through that port, and if not
  • Move to the next port and try again, until it is allowed to pass through the toll.
In some cases, transfer packets sent by bad hackers for will be caught and held at the intersection, where they will then be dissolved into random electrons. When this happens, it is called "packet sniping" or "packet filtering."

What Ports Do "Transfer Packets" Like to Use?

Every software in your computer is typically programmed to send its packets through a fixed port. These port choices are commonly established as programming standards in the computer industry. Accordingly, your router needs to be commanded to allow "transfer packets" through these ports, lest you slow down the speed at which they transfer to/from your computer:
  • HTML pages: port 80
  • FTP file transferring: port 21
  • World of Warcraft: port 3724
  • POP3 email: port 110
  • MSN Messenger: port 6901 and ports 6891-6900
  • Everquest: port 1024
  • BitTorrents: port 6881

So How Does 'Port Forwarding' Factor Into Speed Up Downloads?

Port forwarding is when you command your network router to proactively identify and redirect every packet to travel on fixed electronic lanes. Instead of having every packet stop at each port in turn until it finds an open port, a router can be programmed to expedite the process by identifying and redirecting packets without having them stop at each port. Your router then acts as a type of hyper-fast traffic policeman who directs traffic in front of the toll booths.

While this electronic identification and forwarding only takes milliseconds, the time involved adds up quickly as millions of electronic packets enter and leave your internet computer. If you program your port forwarding correctly, you can speed up your internet experience by several seconds. In the case of downloading large files, like P2P torrent sharing, you can save yourself hours of download time by programming your port forwards. A song that used to take 3 hours to download can now finish in less than 10 minutes if your port forwards are set correctly.

How Can I Learn How to Program My Router's Port Forwarding Commands?

While the programming of port forwarding can be somewhat intimidating, there are tutorials on the internet that can certainly help beginners. The most common reason for programming port forwarding is to improve the speed of BitTorrent downloads, followed by improving the performance of computer games and streaming media. 

Towards these ends, there is a splendid resource by the folks at www.portforward.com. To speed up your specific downloading client, game, or software program: find the exact name of your router and your software, and then visit port forwards website for a visual tutorial on how your router takes port forwarding commands.
