Accessing Roon Core On Qnap NAS by a Roon Remote Not on Same Network

I’m not familiar with networking but I’m trying to determine if it is possible to connect to my roon core that’s on my NAS from a remote that is not on the same network as the core such as over cellular data connection to the internet. And if it’s possible what do I have to do to get this to work

The only reliable solution I’ve found is OpenVPN configured for TAP. Unfortunately I don’t think TAP is supported on mobile devices.

Roon currently only supports all cores, control and endpoints being on the same network subnet. The devs have stated they are looking into a mobile solution in the future.
