ZeroTier Tutorial: Secure Remote Access to Home Assistant & Ubuntu Server + Desktop

For a long time I have checked for a good solution to reach my servers at home. My thoughts now have finalized in the VPN solution Zero Tier(ZT) where I reach Ubuntu desktop with "RDP" and Ubuntu server with "ssh". The ZT solution also works great with the Home Assistant(HA) Mobile App. Until now I have used remote.it but ZT will manage all of my network resources as if they were on the same LAN . The Ubuntu desktop installation is running a Linux KVM with HA and a Ubuntu server Lite guests . Setup here .
