How can I see which devices are making which DNS calls? (PiHole) ...

On my Eero, I set DNS to Custom and have it pointed to my two PiHole boxes. I see all of the DNS calls on PiHole but of course it looks like they're all coming from the Gateway and not the individual devices.

I'm not super knowledgeable wrt networking but it seems like the Eero gateway is doing the DNS lookups /for/ the devices, rather than handing the DNS server IPs to the devices and letting them do it?

Googling around it looks like a common issue. I did notice this:

https://discourse.pi-hole.net/t/majority-of-traffic-through-one-client-eero-settings/12536

So on the PiHole DNS settings I enabled Conditional Forwarding. But it doesn't look like it resolved my problem?

Thanks very much in advance!

p.s. I have disabled Eero secure, both switches.
