What is port forwarding and how you can use it

What is port forwarding?

Technically speaking, this is a process where you enable your router to use a specific port to communicate with certain devices. In other words, a user can tell internet traffic where to go, rather than it going to a location by default. This turns the computer administrator into the air traffic controller of their own data. That is, they can tell the incoming data where to “land.”

Port forwarding can help improve your network efficiency, speeds and security. It isolates your home network from the internet, so it can protect the network by adding a layer of security that limits unwanted traffic and access.

How can port forwarding help your internet connection?

Be forewarned: port forwarding doesn’t necessarily reduce lag. And don’t expect it to work miracles on slow internet speeds. But it can reduce download speeds by a few seconds, and if you are participating in an online activity that is repeatedly or constantly downloading data, such as real-time gaming, those gains can add up to a substantial amount of time saved. 

How does it shave those precious few seconds off of data transport times? By directing “computer signals to follow specific electronic paths into your computer. If the computer signal can find its way into your computer a few milliseconds quicker, it will add up to dramatic speed increases for your game or your downloading,” according to Lifewire. 

What is it commonly used for?

If you do any of these tasks regularly, read on to find out how to set it up in your home or business.

Which internet companies offer port forwarding services?

You should be able to set up port forwarding with a connection from virtually any internet provider. Many even go a step further and offer specific instructions for setting it up on their particular networks and equipment. Here are a few provider-specific guides for several of the major internet companies. 

• AT&T 
• CenturyLink

How to set up port forwarding

1. Find your computer’s IP address and your router’s internal IP address, which may also be labeled “default gateway.” 
2. Open your internet browser and type your router’s internal IP address into the address bar and press enter.
3. Enter your router’s password. This is typically found printed on the router itself.
4. Once you have logged in, find the port forwarding section in your router’s settings, then input the port forwarding number and your computer’s IP address.
