Issues with Pi-Hole (total query, and clients)

Hi!

I’ve installed Pi-Hole in my HA yesterday (my router is an Orbi RBR20) and I got some issues.

First, I’m only seeing one “working” client : my router. I saw that I could bypass this issue by using Pi-Hole as DHCP server but I don’t want to do this. Maybe is there an other solution?

My second issue is about queries. Most of them are from a strange domain (and the number seems pretty high for 2 days of running) :

Is this a known issue with my Orbi? (for both issues).

Thanks in advance.
