Open source ZeroTier is an encrypted virtual network backbone, allowing multiple machines to communicate as if they were on a single network

The code is all open source, and you can self-host the controller or use the ZeroTierOne service with either free or paid plans. Their free plan (cloud based) is robust, solid, and very consistent.

After you have two nodes connected, connecting to each other — no matter where you are or what side of any firewalls you may be on — is exactly what you would expect if you were in the same building on the same network. A primary use case is for remote access to a Home Assistant setup without needing to open up firewall ports or expose it to the internet.

The linked article explains how to get going with it.
