My router (UniFi UDM Pro) is running it's own DNS server but it's extremely limited. However, it does allow for single-record static DNS entries which I use:
For example, my linux server is set with a static DHCP address and a DNS hostname of [server.home.mydomain.com].
However, I'd like to Pi-Hole to add extra A/CNAME (?) records for additional sub-domains (ie. [myservice.server.home.mydomain.com]).
If a client requests *.home.mydomain.com then I'd like Pi-Hole to forward to my upstream UDM Pro router. However, all other requests should go to the main upstream servers (8.8.8.8, etc).
Thiose two statements are mutually exclusive for a given domain :
You either define Local DNS records within Pi-hole, to have Pi-hole provide the respective replies as defined.
Or you configure Pi-hole to conditionally forward DNS requests to another local DNS server (commonly the one on your router) and have Pi-hole supply its answers as received.
From your description, it seems that Condtiional Forwarding is what you look for.
Please follow the respective link and give that a try.
Thanks so much for the reply. I've also read your other post on conditional forwarding but I'm a bit confused on how it works.
How does Pi-Hole determine if a request is for a local machine versus a remote machine?
I'm running Pi-Hole in a podman (docker?) container on my UDM Pro with a static ip address. How does it know that "myserver.home.mydomain.com" is a local request versus "www.google.com" ?
I see that Pi-Hole asks for the local network in the conditional forwarding setup but I still don't see how that helps Pi-Hole understand if a request is for a local network machine.
EDIT: It looks like on my setup I need to specify the "Local domain name" otherwise all requests are going to the public/primary DNS servers.
