QNAP
Install QVPN (recommended)
QVPN provides your NAS with a permanent /dev/net/tun device used by ZeroTier. Once you install QVPN you do not need to open it or configure it: App Center -> Search "QVPN" -> Install. If you opt not to install QVPN you will need to find a way to re-create the /dev/net/tun on each reboot. Good luck.
Install ZeroTier
Determine the type of processor used in your NAS, then download the latest ZeroTier package. Use the App Center's manual package install option to upload the package to your NAS. You will notice a warning icon next to the app notifying you of a missing digital signature. This is merely telling you that QNAP itself has not verified the authenticity of this app.
Due to the lack of documentation on architecture designations selecting the correct package is an inexact science, as far as I can discern there are the following categories. If you don't see your model on this list or you see an error please let us know:

Enable SSH
If you've already enabled SSH access on your NAS, then log into an interactive root shell:
ssh admin@local-ip
Usage
There is no GUI for the ZeroTier package, only a CLI
Upgrading ZeroTier
To upgrade ZeroTier you will need to uninstall the current version of the package and install the desired version. If you wish to preserve your identity you should back up the identity.secret file located in /var/lib/zerotier-one or /share/CACHEDEV1_DATA/.qpkg/zerotier before uninstalling.
