This Knowledge base Article appears lacking.
It has a paragraph that says you don’t need to configure QVPN at all. But what am i supposed to do? Connect with QVPN Does ZeroTier also have to be installed on the nas? How do I specify the network id?
Install QVPN (recommended)#
From the knowledgebase:
QVPN provides your NAS with a permanent
/dev/net/tundevice 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/tunon each reboot. Good luck.
