      @Burnski666 if your pihole points to pfsense, and you want it to resolve those IPs to names - you have to uncheck the box on the pihole to never forward private ranges.

      And pfsense needs to resolve them.. do a query to pfsense via nslookup does it resolve

      example here is a dns query to my pfsense IP 192.168.9.253, asking for the name of 192.168.9.10

      > 192.168.9.10
      Server:  sg4860.home.arpa
      Address:  192.168.9.253
      
      Name:    nas.home.arpa
      Address:  192.168.9.10

        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?

                      and now it resolves my PC

                      7d38cf97-e08d-4bb3-81d1-332e45756cad-image.png

                      but still nothing coming through to pihole.

                        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
