What Is Port Forwarding? A Beginner’s Guide to Port Forwarding


With our lives becoming more dependent on technology, the need to comprehend complex networking concepts has grown. Port forwarding can seem intimidatingly complicated to those unfamiliar with it. So if you’re curious to find out “what is port forwarding?” or want to learn more about it, look no further – you’ve come to the right place!

In this article, we’ll describe port forwarding, its benefits, and how to set it up on your network. We’ll also show you how to implement ports forwarding within your environment.

What is Port Forwarding?

Port forwarding is a networking technique that enables incoming traffic to reach a particular device or service on a private network. When data travels over the internet, it is sent to an IP address and port number explicitly assigned to that device or process. A port is simply a unique number assigned to any operation on that device.

Port forwarding works by routing incoming traffic from a specific port on your router to another device or service on your network. It enables you to access services within your network, such as web servers and remote desktops, from outside its boundaries.

How Does Port Forwarding Work?

Data sent over the internet is sent to a specific IP address and port number. If that port is closed, the router will discard it; if open, it will forward to whatever device or service is listening on that port.

Ports forwarding works by opening a specific port on your router and forwarding incoming traffic to an identified device or service within your network. To accomplish this, create a rule in your router to forward all incoming traffic from that port toward a predetermined destination.

Why Do I Need Port Forwarding?

Ports forwarding can be beneficial in many scenarios, such as running a web or FTP server on your network, hosting a game server, and accessing remote desktop or VPN servers outside your network.

Running a security camera system or other IoT devices

With ports forwarding, you could access these services outside your network.

So how Do I Set Up Port Forwarding?

To set up ports forwarding, log into your router admin interface, locate the port forwarding section, and create a new rule.

  • Enter the IP address and port number of a device or service you would like to forward traffic.
  • Save the Rule

Setting up ports forwarding for your router may differ based on its manufacturer and model. Be mindful that improper setup can have serious repercussions, so follow all manufacturer’s instructions closely and only open ports that are necessary.


Q: Is port forwarding safe? 

A: Ports forwarding can be dangerous if not done correctly, leaving your network vulnerable to attacks. Therefore, only necessary open ports and follow the manufacturer’s instructions carefully when setting up ports forwarding.

Q: Do I Need to Set Up Port Forwarding for Every Device on My Network? 

A: No, only those devices or services you wish to access from outside your network need a ports forwarding setup.

Q: Can I Do Port Forwarding On a Mobile Device? 

A: Unfortunately, no ports forwarding can only be set up through a router.


Port forwarding is an invaluable networking concept that allows you to access services on your network from outside. Setting it up and understanding how it works can seem intimidating, but it’s an essential skill for those running web servers, game servers, or remote desktops. By adhering to manufacturer instructions and only opening ports necessary, ports forwarding can be set up safely on your network so that you can take advantage of its many advantages.

Finally, this brief introduction has given you a good grasp on ports forwarding and how it works. If you have any further queries or require assistance setting up port forwarding on your network, don’t hesitate to contact the manufacturer of your router or an IT specialist for assistance.
