Setup a VPN on Ubuntu 22.04 (Jammy Jellyfish) - Step by step guide ?

A VPN which stands for Virtual Private Network enables a private network to be extended across a public network. It allows users to send and receive data as if their computer equipment were physically linked to the private network. 

For example, suppose you need to connect to your workplace's local network while on a business trip. You'd find an internet connection (maybe at a motel) and then connect to your company's VPN. Although it looks like you are directly linked to the network at work, you are connected to the network via the hotel's internet connection. VPN connections are normally encrypted to prevent unauthenticated users from accessing the local network to which you're connected.

Here at LinuxAPT, we shall look into the different ways in which you can set up a VPN on your Ubuntu.

Ways of setting up a VPN on Ubuntu:

  • Setup VPN Using Command Line Method.
  • Setup VPN Using GUI (Graphical User Interface) Method.
