      Your pfSense problems need pictures of:
      System: General Setup,
      Services: DNS forwarder,
      Services: DNS Resolver,
      Services: DHCP server,
      and the clienthost IPaddress from where you test the speed. :)

          System: General Setup, you do not need "allow DNS serverlist overridden checked.."
          Services: DNS Resolver, listening Network interfaces: select only the inside LAN's,

          Both the clients have received a DHCP-lease, with DNS 127.0.0.1/192.168.1.1 right ? (So no static with own public DNS)
          You have allowed firewall LAN all outgoing ? (at least you want [IPv4 TCP/UDP LAN net * This Firewall 53 (DNS)] )

            That plex issue with secure plex sure seems to be rebinding protection.. Not DNS exactly..  Yeah public domains shouldn't resolve to rfc1918 address space..

            So you could make an exception
            server:
            private-domain: "example.com"

            For the domain your trying to hit, or you could just use a host override to point whatever your accessing outside locally so its not public lookup that returns rfc1918

            Forwarder does rebinding protection as well you would need something like
            rebind-domain-ok=/mydomain.com/

            https://doc.pfsense.org/index.php/DNS_Rebinding_Protections

            In the advanced section of the forwarder to allow your domain to return private IP space.  or you could just turn off rebinding protection.  How exactly are you trying to access plex??

            More than likely your shitty off the shelf routers not going to provide rebinding protection. As to your speedtest… What is the url your using to access that speedtest??

            Me personally I don't access my plex from outside other than with vpn..  Clickity Clickity on my vpn network, click open plex app on phone or ipad there you go.. Same goes for any computer, I just vpn in and hit the web page of my plex server.

              HI johnpoz

              You are 100 percent right, the plex problem was the rebinding and ye lol you where again right shitty routers do not have dns rebinding protection and looks like untangle does not have it  also so A++ to pfsense  :P, I use the phone app or some users use the web browser to access plex, the problem seams to be in using browser but hey it is not worth loosing rebinding protection over it It makes much more sence as you say to use VPN. As for the speedtest I go to speedtest.net and choose my ISP server Madlina, strange part is if i user speedtest.net and select a different server other then my isp it works, and when I specify a public dns in dhcp server madlina works, I turned of dns overwrite in general setup but still same problem

                Hi I removed the overwrite in general
                2 the 192.168.1.2 has a static dhcp set in the pfsense dhcp
                3 resolver listining interface I can not select LAN on its own I get
                The following input errors were detected:

                This system is configured to use the DNS Resolver as its DNS server, so Localhost or All must be selected in Network Interfaces.
                when I select local host I do ot get dns

                  Correct, I forgot to point for Localhost too. Use Ctrl+mouseclick to select LAN(s) and Localhost. (But 'All' should work OK)

                      Then to me it looks like DNSSEC-support problem at test-site.
                      You could test this with unchecking DNSSEC support. But not recommended for the ultimate Resolver use ;)

                      N.B. There is another tough criterium, see Services: DNS Resolver: Advanced (Harden DNSSEC data).

                          How do you pick "Madlina"

                          in speedtest?  I want to look to what IP/FQDN your testing too..

                          What city are you using that allows you to select Madlina?  Can you post a screen shot showing you picking this - see example below

                              Ok I am using resolver and have no issues testing to that server.

                              I would suggest you do a sniff on your machine when you try and test to that server, vs when you test to a server that works.  Or even easier enable debug..  So click on your map before you start test and type debug and you should get a window - see attached… What errors/info do you get in there?

                                No idea I installed pfsense on a different pc and same results it only works when I use public dns.  sorry what do you mean by doing a sniff?

                                  see my edit, enable debug.

                                  Does this resolve, do a nslookup or dig, use dns diag in pfsense

                                          I don't see in there where your even getting the server name you want to test too..

                                          Looks to be more an error in your speedtest applet than any sort of network problem.. Not sure how you can get any test to work if you don't get the server url to go to.. See in my debug where it use the url http://speedtest.melita.com/

                                          I don't see any server url anywhere in that debug log.. did you start it after you click on the server?  Start the debug before you pick your server, and try it with a server that works.  You should see the url your going to for test when you pick a different server.

                                          Also validate that you can resolve
