Please include a "tailscale bugreport", as the template asked for, so we can look into what is going wrong. Subnet routes do work in docker containers.

Timed out.

@DentonGentry I also ran into this issue with similar setup. I tried it on a Synology NAS and a raspberry pi with no luck. Could you please take a look into this?
