      I have Pihole setup to use pfSense for its upstream resolver:

      I dont have Never Forward reverse lookup checked:

      Also, do I still need this:

      EDIT: is nslookup a plugin? I dont see it / cant find it?

          @Burnski666 well if pfsense doesn't resolve it then no anything asking for that IP will not get an answer.

              i disabled pointing my DNS to pihole and just back to the default resolver. did a flushdns and it still doesnt resolve my local PC

                @Burnski666 as I said if pfsense doesn't resolve then nothing will.. If kea is not creating the dns entries from dhcp, then you need to fix that..

                Do you have kea set to register them - it was moved to the kea interface.. before that was like a setting in the resolver.

                  as far as i know/understand, whatever i have setup in pfsense is whatever it was OOTB. Only thing ive changed was setting static IP's for all my devices, and pointed my DNS to my Pihole. Here are a couple screenshots of various pages, maybe something will look wrong to you?

                  Does any of this help/mean anything that might figure out why i cant get hostnames into pihole?

                    3d49e541-1293-46ff-afb7-edb53c783cc7-image.png

                    and now it resolves my PC

                      sweet baby jesus i think it works.

                      i also enabled early DNS since i have mostly static leases

                      32747acf-127d-4fc4-9b3d-b67209b74f0e-image.png

                      and i added my router to the conditional forward in pihole

                      746261e2-0925-4dd5-b1d1-8327392f84c7-image.png

                      and now names are coming through!

                      88e26af6-8b9b-46c3-99d5-bc3039cad357-image.png

                      Am i missing anything else? Do i have any security issues you can see that i inadvertantly created? thanks.

                        @johnpoz hmm ok i thought i was done but maybe not.

                        I have a bunch of smart bulbs. ive gone through and renamed them [ Services -> DHCP Server -> LAN]

                        98966f2f-72e1-4ccc-bea6-85d2eddbdca9-image.png

                        but they still come through to pihole with their default names:

                        4f474660-139b-4a4b-ab80-cec37f44af2e-image.png

                        How do i get pihole to pickup (pfsense to broadcast?) the hostname/description ive assigned it?

                        EDIT: disregard, turns out it was a simple as giving it a few min to update
