ControlD on multiple subnets?

I have two subnets and one DNS server (Ubquiti EdgeRouter) running the ControlD client. The DNS server is NOT my router for access to the internet, it is only performing DNS functionality. The DNS server is on the "inside" (10.10.11.9/24) of my network and responds to DNS request from any "inside" (10.10.11.0/24) clients. I want to also use the DNS server to answer any DNS requests that originate from any IOT client devices (10.10.14.0/24). At the moment, any request that's sent from the IOT network (10.10.14.0/24) to the DNS server are ignored by ControlD. How can I configure it to respond to request from any subnet?

Here is a drawing of the topology - https://www.dropbox.com/scl/fi/8xu1kiwe3u064y67wi0ue/ControlD-Topology.pdf?rlkey=y6eji21jzt6wjfy2rmcbv93xc&st=d7o84g8l&dl=0
