alt Hacker NewsI was about to say that. This is what I do too.
The only drawback are routes - they won't work on the same CIDR (I mean the fact that you can say in Tailscale "if you want to reach the 192.168.16.13 device that does not support Tailscale, go through this Tailscale gateway"). For this I had to shift my parents' network to be able to access stuff like the printer, in a network that clashed with another one of mine.
The way we did it, roting is not a problem. Any Netrinos client (Windows, Mac, or Linux, including the free version) can act as a gateway. It assigns a unique overlay IP to devices on the local network that can't run software themselves, like cameras, NAS units, or printers, and handles the NAT translation.
Think of it like a router's DMZ feature, but inverted. Instead of exposing one device to the internet, each device gets a private address that's only reachable inside your mesh network.
