Introduction
Greetings fellow tech enthusiasts! In today’s digital world, online privacy and security have become critical concerns. If you’re an Ubuntu user, then you’ll be happy to know that setting up a VPN server is easy. A VPN (Virtual Private Network) service can help you protect your online identity, secure your internet connection, and bypass geo-restrictions. In this article, we’ll go through the step-by-step process of setting up an Ubuntu VPN server.
Before we begin, let’s take a moment to understand what a VPN server is and how it works. A VPN server is a powerful tool that creates a secure and encrypted connection between your device and the internet. By connecting to a VPN server, your traffic gets routed through it, making it difficult for cybercriminals, internet service providers, and other prying eyes to snoop on your online activity. Moreover, a VPN server can also give you access to geo-restricted content by masking your IP address and location.
In the next few sections, we’ll explore how to set up an Ubuntu VPN server, its advantages and disadvantages, and some frequently asked questions.
