In this tutorial, we will tell you how to install PPTP VPN on CentOS 8. You know, PPTP stands for Point to Point Tunneling Protocol. This is a traditional protocol for implementing VPS networks.

A Virtual Private Network (VPN) is a connection method used to add security and privacy to private and public networks, like WiFi Hotspots and the Internet. Most of the time, corporations will utilize VPN to protect sensitive data. Or, ordinary web users will use them in parts of the world where there are government restrictions on internet content. Privacy is increased with a Virtual Private Network because the user’s initial IP address is replaced with one from the Virtual Private Network provider.

In other words, when you use a VPN, your IP address is hidden to give you more security and protection. It also helps you to surf those blocked and banned websites you wish to visit.
