ZT to manage remote networks?

I’ve become the defacto “IT Guy” in my family. I’ve moved pretty much all of them to MikroTik routers. The new version of MikroTik’s router OS has a ZT implemenation.

What I’d like to do is set up ZT so that I can manage their routers/whatever remotely and securely. ZT seems like it might be the ideal way to do this, as opposed to using a real VPN server.

I believe that this would be possible, though I can’t quite grasp how I would do this propertly.

Essentially, I want to be able to be on the ZT network with them, however I don’t want them to be able to access any part of my network. Is this feasible?
