Introduction

VPN (Virtual Private Network) is used to change the IP address of a device and gives you freedom of connecting to any private server in the world. It makes you safe from hackers and provides you safety of your personal information, activities that you do on the internet and hides your identity. It also helps in accessing restricted and blocked websites.

Tunneling is a process that helps in secure, encrypted and fast browsing, sharing, downloading, streaming etc. It is used in VPNs for data transferring on the internet. 

Let’s understand how tunneling is accomplished in VPN.

How does tunneling work in VPNs?

Tunneling basically works by encapsulating packets. It’s essentially an information packet inside another information packet. These packets then travel through the VPN tunnel where this traffic is encrypted.

It starts by encrypting the data and changing it into a non-decipherable code. The encrypted data is enclosed in the secure "tunnel" created by additional data packets that include headers and routing details. The information is sent through an VPN server that hides the IP address of the source which improves security. That’s how tunneling is accomplished in VPNs.

Diverse Tunneling Protocols

There are many VPNs like nordvpn, quickvpn, expressvpn etc. that you can use, and they all use different protocols for uniqueness. The decision of choosing protocols is based on different-different factors like safety and loading speed.

It consists of data encryption, packet encapsulation, decapsulation at destination, routing through VPN servers, and secure transmission.

Conclusion

Without tunneling there will be no meaning of VPN because it is a main foundation of this VPN concept. Its only work is to provide you a secure browsing experience by hiding your IP address and making you anonymous on the internet. In simpler terms tunneling in VPN is like putting a mast so no one can locate your location, activities and collect any data.
