      @scorpoin said in DNS issue:

      All I want is

      No, you do no want that.

      Your second image instructed pfSense that it should give 8.8.4.4 and 8.8.8.8 to your devices.
      And so they use 8.8.4.4 and 8.8.8.8.

      Do what I said above : locate these servers 8.8.4.4 and 8.8.8.8, install pfBlokcerNG also on them, and you'll be fine.

      Ok, I known, I'm silly.
      Just believe me : DITCH 8.8.8.8 - 8.8.4.4 etc etc etc
      Use a DNS server to forward to if you pay them, like OpenDNS, which is actually a service very comparable to what you decided to do locally : pfBlockerNG.

      @scorpoin said in DNS issue:

      but what if a client use static ip and static dns 8.8.8.8 and 8.8.4.4 then how to block such clients.

      First of all, 8.8.8.8 etc is not the Internet.
      You think it is.
      Internet worked fine 30 already 30 years before they came.

      I even block all these 'free' DNS server IP using pfBlockerNg :
      Bad for them if they try to use them. As an admin I've said that the local gateway is the networks DNS = pfSense.
      Not some other hard coded DNS server.

      Even my TV set - some smart TV, in power down mode right now, is hitting 8.8.8.8 all the time.
      Interessting.
      Scrw it.
      ( and it just works fine without 8.8.8.8 - as it will use pfSense to do the resolving ...
      It's using 8.8.8.8 for the telemetric / usage / and of course so it has a backup DNS if the local admin f
      ck*d up the local DNS, as it happens a lot these days )

      Edit : and where are the logs ??

        I've removed other DNS and only added PFsense IP there .

        When giving a static ip to my test machine with public dns . it is working even giving opendns ip it is working too. Do I have to add some kind of list in pfblocker.
        Now still the same situation :/ .

          172.16.159.254 is your pfSense LAN IP ?

          Some devices use 853.
          You do not block 853 for !172.16.159.254 .....

          Btw : listing a snipped of firewall rules is useless.
          All the rules have to be taken in account.

          What if you were hiding a initial :

          20562dae-0667-46ae-83db-f35f75aededc-image.png

          ?

          Or not telling about some floating rules ?

          pfBlockerNG : see the image I showed above. You can see the name of the feed that blocks public DNSs.

          Also check out Firewall > pfBlockerNG > DNSBL > DNSBL SafeSearch

              I've have no firewall rules to block any DNS.
              I'm forcing devices to use my (pfSEnse) DNS.

              Just pfBlockerNG - using these feeds :

              66baef33-047f-4c6c-a791-d3c1cef5e52d-image.png

              and

              15bd8097-d686-4172-9960-744db0eafdcc-image.png

              and, as you can see, I block mostly [whatever]:53

                    You use pfblockerNG, right ?
                    On the "Feeds" page.
                    Firewall > pfBlockerNG > Feeds
                    Hit Ctrl-F
                    Type Great
                    Hit enter.
                    You find two lines : the two images I showed you above.
                    Click on the word Great.
                    Github opens.
                    Click on the link "heGreatWall_ipv4.txt"
                    Hit Ctrl-F
                    Type 8.8.8.8
                    Hit enter.
                    You found the place where 8.8.8.8 is blocked - if you use this feed.
