Ever seen a tunnel that makes its way through a mountain to connect the world at both of its sides? I am sure you would have definitely seen it, at least once in your lifetime while on a journey on rails. Now think of a VPN tunnel. Yes, you guessed it right! It also serves the very much similar purpose, i.e., creating a connection (of networks) between two separated or remote locations to transfer encrypted data.

What is VPN tunnel?

Going by the definition, tunneling is a technology that allows a network to transmit data through a connection that is established at some other network. It is this basic rule that guides the working of VPN and hence the name VPN tunnel comes into existence.

How VPN tunnel works?

To assure data integrity through VPN tunnel, the data packets are constructed in any of the widely used VPN protocols and are then encapsulated in a carrier protocol. After being transmitted to the intended server from the VPN client, they are de-encapsulated to obtain the data in its original form, without being doctored by any third party.

So what are these protocol types?

An array of cryptographic protocols can be used for VPN tunneling thereby assuring a secure communication over a private connection. Some of the most prominent ones include:

• Point-to-point Tunneling Protocol (PPTP):  It makes way for a secure message transmission from VPN node to another. Windows provides specific built-in support for this protocol.
• Layer Two Tunneling Protocol (L2TP): It combines the features of Layer 2 Forwarding (L2F) and PPTP protocols, respectively. It assures data confidentiality and when used in sync with IPSec, it also provides data integrity, replay protection and data authenticity.
• Secure Shell Protocol (SSH): It comprises of a SSH tunnel that transfers unencrypted data over a secure network with the help of an encrypted channel.
• Secure Socket Tunneling Protocol (SSTP): It is among the latest protocols to be used for traffic transmission from one end to other, bypassing the web proxies and firewalls. It uses HTTPS protocol and can prove to be worthwhile where protocols of the likes of PPTP and L2TP/IPSec fail to make a mark.
