Configure OpenVPN to Remotely Access Your Home Network

Recently I configured SSHd to run on one of my raspberry pi's at home, using Tor to make it accessible remotely even without a static IP, or custom forwarding rules with my routers. This time, I am going to accomplish a similar goal, however using OpenVPN and a cheap $5/mo server from Linode or DigitalOcean. (Next post we will discuss hosting websites from home using this VPN Tunnel).

What is the end goal?

Simply put, I want to host services (ssh, sftp), websites (http, https), & email (smtp, pop3, imap4) from my raspberry pi cluster at home, without purchasing a Static IP or using services like DynDNS. While DynDNS is awesome, there are some issues with DNS Caching which could make the cluster unavailable for periods of time.

OpenVPN Server Configuration

Replace the /etc/openvpn/server.conf with the option below
