Got an idea from below one:

What if you add below dnsmasq directive?

trust-anchor=171.168.192.in-addr.arpa.

EDIT: For example:

$ sudo pihole-FTL --config misc.dnsmasq_lines
[]

$ sudo pihole-FTL --config misc.dnsmasq_lines '["trust-anchor=171.168.192.in-addr.arpa."]'
[ trust-anchor=171.168.192.in-addr.arpa. ]

$ sudo pihole-FTL --config misc.dnsmasq_lines
[ trust-anchor=171.168.192.in-addr.arpa. ]

You can also find that "Expert" setting on the webGUI.
Probably not gonna work but worth a try :wink:
