        look at the wireshark print.
        The dns query has 2x localdomain.

        It should be teste.localdomain.
        And its showing teste.localdomain.localdomain.

        Something must be wrong in DNS configurations. Is the PC configured to use localdomain domain?

          PC 192.168.145.11
          DNS
          192.168.145.1

          the icmp i did is from 192.168.145.12 "ping teste.loocaldomain" in ubunto console

          im gonna try to ping teste.localdomain.loocaldomain to see what happens

          UPDATE: PC 192.168.145.11 recognize localdomain as domain and cant ping teste.localdomain

                Well clearly you could not talk to 145.1 on 53 then... Or its not listening..

                BTW having your clients point to both pfsense and some outside dns is just a borked config out of the gate... google sure and the hell not going to resolve anything.localdomain -- you can never be sure which NS a client will ask when it has more than 1 listed. So if your going to point a client to more than 1 NS, all of the NS need to be able to resolve the same stuff.

                Validate your unbound is actually running..

                And I can tell you this wrong more than likely

                Outgoing Interfaces == LAN

                So unbound is suppose to resolve say something.publicdomain.com via its lan interface? What would it be talking to on your lan that would allow it access to the internet to do that?

                Vs you stating what you believe are the settings. Your host override there.. Is it actually in unbound, or do you have it maybe setup in the forwarder? But from your nslookup there you can not even ask unbound anything, or its not even running or you get back either a nx or servfail or resfused... not a timeout. Or unbound was trying to resolve something and it timed out looking for it - maybe because its trying to resolve via the lan interface? since you don't have your host override setup correctly?

                Try resolving pfsense name for a test.. Post up your actual rules on the interface this client is on. Validate unbound is running and listening.. Validate your host override in the correct place..

                [2.4.4-RELEASE][admin@sg4860.local.lan]/root: ps -ax | grep unbound
                60328  -  Ss        0:51.70 /usr/local/sbin/unbound -c /var/unbound/unbound.conf
                

                So you can see its running from above, and here is listening on my lan IP

                [2.4.4-RELEASE][admin@sg4860.local.lan]/root: netstat -anl | grep 192.168.9.253.53
                tcp4       0      0 192.168.9.253.53                              *.*                                           LISTEN
                udp4       0      0 192.168.9.253.53                              *.*                                           
                

                Here is host override and test of it

                  @Rafel-S clearly the service is not running... try to see if the DNS service is actualliy running on port 53.

                      i don't see service running. check the status menu.

                              check if dns forward is causing it to stop.

                                  And what is running on 53? Your not showing what pid is listing on 53..

                                  Here do this.

                                  sockstat | grep .53

                                  example

                                  [2.4.4-RELEASE][admin@sg4860.local.lan]/root: sockstat | grep .53
                                  unbound unbound 33787 3 udp4 192.168.3.253:53 :

                                        So you have nothing running on port 53... And unbound wont start for why? What is in the log?

                                            In the system log..

                                            When you try to start the service.. disable it, and then re-enable it.
