A VPN tunnel is created when a connection is established between two devices through a VPN server. This server encrypts the data passing between the two devices and makes it unreadable to anyone who might intercept it.

Introduction
‘Tunneling’ is a technique used to secure Internet traffic. It involves encapsulating data in an outer layer of encryption before sending it over the public network. This protects the data from being intercepted and read by anyone other than the intended recipient.
There are a number of different ways to tunnel data, but the most common is to use a Virtual Private Network (VPN). A VPN creates a private, encrypted tunnel between your computer and a VPN server. All of your Internet traffic passes through this tunnel, so it cannot be intercepted or read by anyone else.
VPNs are commonly used by businesses to allow remote workers to securely connect to their corporate network. They are also used by individuals to protect their privacy when using public Wi-Fi networks.
What is a VPN?
A VPN, or Virtual Private Network, is a service that allows you to connect to the internet securely and privately. When you connect to a VPN, all of your internet traffic is routed through an encrypted tunnel. This means that no one can spy on your internet activity or see what you are doing online. Tunneling is what makes a VPN so effective at protecting your privacy.
What is a Virtual Private Network?
A VPN, or Virtual Private Network, is a secure tunnel between two or more devices. VPNs are used to protect private web traffic from snooping, interference, and censorship.
A VPN encrypts your web traffic with military-grade technology and sends it through a secure tunnel to a server in another location. That server then decrypts your traffic and sends it on to the internet.
Because your traffic is encrypted and sent through a secure tunnel, anyone intercepting your traffic will only see gibberish – they won’t be able to see what websites you’re visiting or what data you’re sending.
Additionally, a VPN can spoof your location by making it appear as though you’re accessing the internet from another country. This is useful for accessing geo-blocked content or bypassing censorship filters.
VPNs are an essential tool for online privacy and security.
What is a Tunnel?
In computer networks, a tunnel is a point-to-point connection between two or more nodes. tunnels are used to send data securely over a network, as well as to connect multiple networks together. Data that is sent through a tunnel is typically encrypted, making it difficult for anyone who does not have the encryption key to read the data.
Tunnels are created by combining two or more existing network connections, which are then used to route data between the nodes. Tunneling is often used in virtual private networks (VPNs) to connect remote users to a private network. It can also be used to connect two separate networks together, such as a corporate intranet and the Internet.
How is ‘Tunneling’ Accomplished in a VPN?
In order for a VPN to work, data must be “tunneled” through a secure connection. This process encrypts your data and makes it unreadable to anyone who does not have the key to decrypt it. This is how a VPN protects your privacy and security. But how is this accomplished?
The Process of Tunneling
In computer networks, tunneling is the process of sending data from one network to another. In theory, any data can be sent this way, but in practice, only certain types of data can be sent efficiently. The most common type of data sent through tunnels is Internet Protocol (IP) traffic.
Tunneling works by encapsulating data in one network and sending it to another network through a tunnel. The tunnel is established by encapsulating the data in a packet, which is then sent to the receiving network. The receiving network decapsulates the packet and sends it to the destination host.
Tunnels can be used to send data over public networks such as the Internet or private networks such as corporate Intranets. In both cases, the tunnel provides a secure path for the data, preventing it from being intercepted or tampered with in transit.
Types of Tunnels
In order to create a tunnel, both the sender and the receiver must be using VPN software. When data is sent over the public internet, it is susceptible to interception by anyone with malicious intent. In order to prevent this from happening, VPN software encrypts the data before it is sent, and decrypts it upon receipt. This process is known as ‘tunneling’, and there are two main types of tunnels that can be used:
-Point-to-Point Tunneling Protocol (PPTP)
This type of tunnel uses 128-bit encryption, and is typically used for lower-bandwidth applications such as email or remote desktop access.
-Layer 2 Tunneling Protocol (L2TP)
This type of tunnel uses 256-bit encryption, and is typically used for higher-bandwidth applications such as streaming video or gaming.
Conclusion
Tunneling is the process of encapsulating data within other data. A VPN tunnel is created by encapsulating data from one network within data from another network. This process allows for the secure exchange of data between the two networks. Tunneling is a key component of a VPN, as it allows for the secure exchange of data between two separate networks.
