I want to use the internal Samba DNS server, forwarding to a recursive DNS server (Unbound) running on the same host. Samba takes port 53, so Unbound needs to listen on another port, but Samba cannot be configured to talk to a port other than 53 on the configured DNS forwarder.
I should be able to use `dns forwarder = 127.0.0.1:53530` or `dns forwarder = [::1]:53530` to forward DNS queries to localhost on port 53530.
While this is not possible at the moment, I agree that this would be a good idea to get set up.
Setting host:port has landed in master and is scheduled for 4.16.
