However, it can be risky if you don’t know what you’re doing. Therefore, you’ll need to understand three things: what is port forwarding, is it safe, and how to perform this operation without jeopardizing your network. We’ll tell you all about it.

What is port forwarding?

The explanation is quite technical, but we’ll try to simplify it. If you access the Internet through a router on your network, you will need to forward ports so that external traffic could access your network. For instance, if you want to host a public game server, you will need to open some ports on your network, so that other players (clients) that are not on your LAN (Local Area Network) can connect to it. Since your router is configured by default not to allow any external connections, you will need to perform these operations manually. Your router acts as a firewall and only permits access to a few services. Essentially, port forwarding is enabling external devices to connect to a certain device or service within a private LAN.

Is port forwarding safe?

The short answer is yes; port forwarding is not inherently unsafe. The safety of this procedure depends on a variety of factors. For instance, if you run a service that’s out of support and has a lot of unpatched vulnerabilities, then you’re putting your PC and network at risk. On the other hand, if you just want to host a public game server, you should be fine. However, you should make sure that there’s no other software/service that acquires the ports you previously assigned whenever the game server is not up and running. You can increase your security by setting up restrictions. For example, you can limit traffic by country or even by IP address (whitelisting). Additionally, it would be good practice to limit bandwidth, so that you don’t receive DDoS attacks. The bottom line is that port forwarding is not inherently unsafe as long as you’re careful about what you run through those ports. Last, but not least, one of the safest practices would be closing the port whenever you’re not using it. Assuming that you know what you’re doing and the risks involved, let’s see how to open ports on your router. Performing this operation is different from one router to another. For obvious reasons, we won’t show you how to do this on every router. Instead, we’ll give you the know-how, so you can manage in any given situation, with any router.

How to port forward?

Can’t forward ports because of a double NAT situation? Our extensive guide will teach you how to fix it quickly. That’s it. If you want to test if you’ve done everything correctly, you can use the PortCheckTool website. Type your desired port in the field and hit the check button.

VPN port forwarding

Many users rely on VPNs to maintain their network security and online privacy. In time, users wanted a way to perform port forwarding while using a VPN, so a few providers have implemented this feature in their services. For instance, PIA is one of the best VPN providers that has native support for dynamic port forwarding. It has passed all of our security, speed and flexibility tests with flying colors. Performing this operation through VPNs can come in very handy in some cases. For instance, it can help increase torrent download/upload speed values and multimedia streaming speeds. Additionally, you can use it to access your PC remotely when you’re not physically around it.

Safe and useful operation if done right

To sum it up, if you want to make a local service/device accessible from outside your network, port forwarding is usually the answer. It’s not risky as long as the service you run on that port is safe. How to forward ports highly depends on the model and brand of your router. Some devices might use different names for this operation. For instance, TP-Link uses Virtual Servers. You can even forward ports while using a VPN, but for that, you’ll need a port-forwarding-friendly VPN.
