Hardware Port vs Software Port

A hardware port is what you use to physically connect devices and/or device cables to your computer or network. You can find many of them on the back of your computer or router.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

NordVPN is the fastest VPN!

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

There are hardware ports for connecting your mouse, keyboard, and printer to your computer. You can also find USB ports on your computer or laptop that you can use to connect devices like cameras, phones, iPods, and USB sticks.

The photo below shows the hardware ports found on the back of a desktop computer.

And here are the hardware ports on a router.

Software ports are an important part of internet addressing and help to define the destination for packets of data.

Software ports allow your computer to have more than one application accessing data (on a network or the internet) at the same time. Each application is designated a port number (or port) to use for transferring data. This process of addressing ensures that the receiving computer can know which program to use for the data it receives. It is similar to the way a phone network works where the number gets you to the building of the business and the extension gets you to the correct department.

Below is an example of the port forwarding section on a router. These are software ports.

Certain services and applications commonly use specific port numbers. For example, e-mail is reserved for port 25 and your web browser uses port 80. Many applications know which ports to listen to and can differentiate between the packets of data that are meant for them and the traffic that they can ignore. Here is a list of common port numbers for specific services.

How can I specify a port?

Normally data is processed automatically by hardware and software so you do not have to deal with ports. However, there are some instances where you will want to know how to specify ports such as the following:

  • When connecting to a personal game server
  • When configuring a Utorrent client
  • To allow port forwarding for specific applications to pass through a router
  • When connecting to an IP security camera

You can access a specific port by knowing the IP address of the network or device and the port number of the program. For example if you want to access your IP security camera that is located at on your network and you have it set up on port 8080 (which is a common default for security cameras) you would go to your web browser and type in the address:

Port Forwarding

With a router, you can have all traffic destined for a specific port sent to a certain IP address on your network. This is known as opening a port or forwarding a port, when you define where that service lives on your network.

Is my Port open?

To verify that a specific port is open on your computer or network you can use PF Port Checker, free software from PortForward.com that will test your ports for you automatically.
