How is tunneling accomplished in a VPN?

At first, VPN may seem like magic. However, it is a real technology. It does not require any magic to work.
People are becoming increasingly aware of dangers to their online privacy and security. This has created an opportunity for VPNs to rise in popularity. They play a crucial role in protecting our internet connections and naturally, question of how is tunneling accomplished in a VPN slowly started getting some interest.

Tunneling is one of the key technologies used by VPNs, which helps create a secure pathway for our data to travel. In this article, we will explore how is tunneling accomplished in a VPN, explaining the process in simple terms.

What is Tunneling?

Tunneling is a process used in VPNs. It involves adding an extra layer of security to data before it is sent across the internet. It’s like putting your information inside a protective shield to ensure its privacy and integrity.


To accomplish this, VPNs use encryption. Encryption is a way of scrambling your data so that it becomes unreadable to anyone who tries to intercept it. It’s similar to using a secret code that only the intended recipient (in this case, the VPN server) can decode.

Encapsulating Your Data

Once your data is encrypted, the VPN software or app takes it and puts it inside a virtual tunnel. This tunnel acts as a secure, private pathway between your device and the VPN server. Think of it as a secret passage that nobody else can access.

Routing through the Tunnel

Next, your encrypted data travels through this tunnel, bypassing the regular internet traffic. The tunnel protects your data from prying eyes, such as hackers, ISPs, or even government surveillance. It keeps your information safe from unauthorized access. If the VPN provider is trusted of course, keep an eye on their policies!

Arriving at the VPN Server

When your data reaches the VPN server, it is decrypted. The VPN server is the endpoint of the tunnel. It receives your data and decrypts it. This is done using the same encryption key used to encrypt the data.

This allows the VPN server to understand your data and perform the necessary actions on your behalf.

Sending Data to the Destination

After the VPN server decrypts your data, it acts as your representative on the internet. It forwards your requests to the intended websites or online services, receiving the responses on your behalf. It then encrypts the responses, puts them back inside the tunnel, and sends them securely back to your device.

Does tunneling protects my anonymity?

It’s not rare to hear this question, and it must be said that VPN is not a tool that you use to be anonymous. VPN is a tool with many uses, but anonymity is not a thing that it provides.

For example, it can protect you from attackers when you are connected to open public networks. It can also make it appear as if you are in a different location. These are just a few of the many usages of VPN.

It protects your privacy, but privacy does not equal to anonymity.

What provider is the best?

Hard question to answer. If you prioritize privacy and security, you must search thoroughly for a trustworthy provider.

Most of the popular ones are usually the most suspicious ones. Keep that in mind while researching who is behind certain companies and what their true intentions could be. As always, when it comes to online privacy and security, keep all four of your eyes wide open!

And if you are unable to find a suitable provider, you can always build your own VPN on a VPS server using OpenVPN. You won’t have access to many different locations, but you will have all the other benefits while being in the full control of your data.


Tunneling is a fundamental technology that enables VPNs to provide a secure and private connection.

By encrypting and encapsulating your data, VPNs create a virtual tunnel that shields your information from potential threats. We can better appreciate the significance of VPNs when we understand how tunneling works. VPNs provide us with online security, privacy, and enhanced digital safety.

That is all for today folks, we hope this helped you understand how is tunneling accomplished in a VPN a little better and we encourage you to keep digging and learning more about it. Go on, knowledge is waiting for you!
