Running a Tailscale subnet router inside a container for access to a specific site. I’ve been trying to see if I can route requests for DNS over the Tailscale VPN to but haven’t had any luck so far.

Is it possible to configure devices behind a subnet router to get DNS responses from MagicDNS or do I have to create my own for split-DNS?

I can ping from a device in the subnet, so I know my routing rules are correct and the device is online, but DNS queries to it fail.
