Self hosted open source mesh VPN with IPv6 support!

Anurag Bhatia
A rather long title but the post is about self-hosted open-source mesh VPN with IPv6 support and works with nodes behind CGNAT! This will be a long post documenting the concept of mesh VPN, the problem it is solving as well as a working demo. If you are not planning to deploy it right away, you can skip the post after the “Configs and setup” section. Problem I am running a site-to-site VPN for a long time between various servers located far away from each other.
