Part Three: My Virtualized OpenVPN Server

Overview

In this post, I'd like to share my most recent home lab project - a nested OpenVPN server. I refer to it as nested, because it is running completely within my desktop computer. See the illustration below.

The idea for this project came along when I working on setting up a VPN with my older Linksys router. Basically, I wanted to come up with a way to run a home lab VPN server without requiring any additional hardware, and I wanted to incorporate virtualization into this project. In addition, running it as a VM allows for fairly safe and controlled experimentation, without running the risk of bricking one's router with non-standard firmware.

Part Two: Generating a PKI (Public Key Infrastructure) for my OpenVPN Deployment

In part one of the DIY home VPN experiment, I introduced the project that I am working on - a client-server VPN utilizing OpenVPN. I will be deploying a VPN server using three different methods: 1) a VM running on VMware Fusion, 2) using CentOS on a Raspberry Pi, and 3) using DD-WRT on a consumer router; however, I would like to begin by building the common foundation - the PKI.

What is a PKI, or public key infrastructure?
