Overview

This documentation provides a comprehensive guide to setting up a Virtual Private Network (VPN) server using Pritunl, a popular open-source VPN server management platform. By following these steps, users can establish a secure and private network infrastructure suitable for various applications, such as remote access, secure communication, and data privacy.

Prerequisites

• AWS account: Users must have an active AWS (Amazon Web Services) account to create and manage instances on the cloud platform.
• Instance creation: An EC2 instance needs to be created in the desired region (e.g., Mumbai) using the Ubuntu 22.04 AMI. Users should ensure that ports 80, 443, and 22 are allowed in the security group settings.
• Access to the instance: Users need SSH access to the instance created on AWS. They should possess the private key associated with the EC2 instance to establish a secure connection.
• Web browser: A web browser, preferably Google Chrome, is required to access the Pritunl dashboard and configure the VPN server settings.
• Pritunl client: To connect to the VPN server from client machines, users must install the Pritunl client application. The client can be installed on various operating systems, including Windows, macOS, and Linux distributions.
• Network configuration: Users should ensure proper network configuration, including DNS settings, virtual network details, and firewall rules, to establish seamless communication between the VPN server and client machines.

Setting up a VPN Server

Step 1: Setup Instance

• Launch an instance in the Mumbai region using the Ubuntu 22.04 AMI.
• Ensure ports 80, 443, and 22 are allowed in the security group.

Steps for Launching Instance

• Select the Mumbai region.
• Launch an instance, providing a name.
• Choose the specified AMI.
  
• Select t2.micro instance type
• Choose or create a key pair
• Select the default VPC and adjust network settings if necessary
• Allow SSH, HTTP, and HTTPS ports in the security group
• Launch the instance

• Step 2: Access the Instance and Setup VPN

• SSH into the instance: ssh ubuntu@yourip -i “key”
• Switch to root: sudo -i
• Execute the following commands

sudo tee /etc/apt/sources.list.d/pritunl.list << EOF

deb http://repo.pritunl.com/stable/apt jammy main
