This is exactly what I do with my Unifi router, but still all I see in Pi-hole is the router making the DNS requests.

I think you’ve set the WAN dns to the PiHole. You need to set the DNS in networks.

Are you NATing the redirection to the pi hole server? If so, disabling it should let pihole see unique clients.
