/dev/net/tun on each reboot. Good luck.
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.

/share/CACHEDEV1_DATA/.qpkg/zerotier before uninstalling.
