I’m also discovering subnets as we speak.
Some people suggest Site-to-site networking, but it is not the case here. It is aimed to reach one specific tailscale-host from a non-tailscale-host
Request –> Tailnet –> Subnet Router –> Host
I confirm it works this way, well, it is intended to.
Host –> Subnet Router –> Tailnet –> Tailscale Host
If you haven’t tried it yet, I can confirm this way doesn’t work with the original settings
Hope somebody helps us
EDIT
I solved the issue by following this user’s footsteps.
DO NOT FORGET to “tailscale up –accept-routes” on the tailnet linux-machines that you want to reach
