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.
