If you are using a VPN on a regular basis, then you might be interested in knowing about the best site-to-site VPN services available for Windows, Mac, and Linux users.

Site to Site VPN is an extension of Virtual Private Network (VPN) technology that allows two or more remote sites to connect over the Internet.

We will explain the basic working principle and how different VPN tunnels
work in terms of security and speed. 

So, without any further ado, let’s get started with our guide!

How Does Site To Site VPN Work?

Site-to-site VPNs allow you to access your company network from anywhere in the world securely. It also gives you complete control over what data gets sent through the tunnel.

This means that even if someone manages to hack into one of your computers, they won’t be able to access anything sensitive.

Site-to-site VPNs use encryption to secure all traffic between the client and server. Encryption ensures that no other person can intercept the information being transmitted. The encrypted data is then passed through the public internet before reaching its destination.

The main benefit of site-to-site VPNs is that they provide complete privacy and security to your employees. They help protect against hackers who may try to steal confidential documents from your computer system.

In order to set up a site-to-site VPN, you need to have at least 2 devices connected to the same network. You can either be using them as clients or servers. Let’s take a look at each of these options.

Client Device – A device that needs to be connected to the network so that it can access resources within the network. For example, a laptop or desktop PC.

Server Device – A device that has all the necessary software installed to act as a gateway between the client and the rest of the network. In most cases, this would be a router.

Once both devices are connected to the same network, you can start configuring the site-to-site connection.

What are VPN Tunnels?

A VPN tunnel is nothing but a virtual private network that connects two or more networks together. All traffic is routed through the VPN tunnel. This makes sure that none of the data is intercepted by anyone else while it travels across the public internet.

There are Three Types of VPN tunnels:

  1. OpenVPN – An open-source protocol used to create VPN connections.
  2. IPSec – A proprietary protocol that is used to create VPN connections
  3. L2TP/IPsec – A combination of IPSec and PPTP protocols.

OpenVPN is considered to be the most secure type of VPN tunnel. It uses strong encryption algorithms such as AES 256 bit and SHA 512 hash functions. These make it difficult for anyone to decrypt the data.

OpenVPN is an open-source protocol developed by Cisco Systems. It was created to support remote users who want to connect to their corporate network remotely. It allows multiple users to log on to the corporate network simultaneously.

IPSec is another popular VPN protocol. It is designed to encrypt data packets. It is mostly used when you want to share files securely between two locations.

L2TP/IPSec – This is a combination of IPSec and PPP protocols. It is used to create VPN tunnels between two different networks. L2TP/IPSec works like any other VPN tunnel. However, it takes advantage of the Point-to-Point Tunneling Protocol (PPP) to establish the connection.

When you’re setting up a VPN tunnel with L2TP/IPSec, you’ll first need to configure the PPP connection. Once this is done, you will need to configure the IPsec connection.

Conclusion 

In conclusion, a site-to-site VPN is one of the best ways to ensure that sensitive data remains safe. It provides full protection against hacking attempts.

It also helps in protecting against malware attacks. This article explained how a site-to-site VPN works.
