Setting up OpenVPN Access Server in Amazon VPC – AWS

Pre-requisite:- Virtual Private Network and AWS

A VPN is a secure connection that allows you to connect to the internet through a private, encrypted network. When you use a VPN, all of your internet traffic is routed through a secure server and encrypted, so that third parties cannot intercept it. This is useful for protecting your online privacy and security, as it prevents others from being able to see what you are doing online or from accessing your personal information. VPNs are often used to protect against online surveillance and cyber threats, and they can also be used to access content that might be blocked in certain regions or countries.

Amazon Web Services

Amazon Web Services (AWS) is a cloud computing platform provided by Amazon. It offers a wide range of services, including computing, storage, networking, database, analytics, machine learning, security, and more. These services are provided over the internet, and they can be accessed through APIs or through the AWS Management Console, which is a web-based interface for managing AWS resources.

OpenVPN Access Server

OpenVPN Access Server is a software package that allows you to set up and manage a VPN (Virtual Private Network) server. It is based on open-source OpenVPN software and provides a secure and private connection between devices over the internet.

OpenVPN Access Server is designed to be easy to install and manage, with a web-based administration interface that allows you to set up and configure the VPN server quickly and easily. It supports a wide range of client platforms, including Windows, macOS, Linux, iOS, and Android, and it can be used to connect a variety of devices, including laptops, smartphones, and tablets.
