remote Time Machine

I'm not a Mac user, so know nothing about Time Machine.  Most VPN's join two networks together, which is often what you want.  ZeroTier, on the other hand, adds a network in parallel, wihc works better for me.  Each device running ZeroTier has it's normal IP address and a separate ZeroTier address that looks just like another IP.  Normal traffic runs through the standard internet connection and traffic specifially addressed to a ZeroTier address goes through ZeroTier.  I would think that it would work with Time Machine -- you just specify the NAS ZeroTier address instead of it's IP address.  But you'd have to give it a try to see or see if someone in th ZeroTier community can help out.

Yes I have tried to set up a VPN between 2 routers. However, the internet provider of at least two sites also provides the modem/router. I cannot set up a VPN on that router: it is not an available option.

That device also other services and the provider is not willing to share the necessary data to set all services up on devices that I would install. So, stuch with that provider for the moment for a few locations.

Thanks, maybe ZeroTier is a good solution at least untill I get the provider changed.

But since Netgear claims it is possible, hope to learn how to do it without ZeroTier as well.

Unless I learn more on the Netgear solution within the next days, I will try ZeroTier.
