Subnet routers: how do they work?

They are great, I have one on my proxmox host at home, and can reach all my containers and VMs that way.

If anyone from tailscale see this comment, one important thing missing on this page is a link to the documentation. The video does explain things, but including the link to the documentation for reference and further learning would be quite useful.

Does anybody else have trouble with tailscale "site-to-site" subnet routers -- deployed on Linux firewalls -- messing up their routing?

If so, what has worked for you?

(Edited to replace point-to-point with site-to-site.)

At least this should be labelled as an ad, as it's barely informational. That and the fact that wireguard is much better solution.
