      @orphen76 said in DNS Resolver doesn't work:

      Address: 103.86.96.100

      Who is that 103.86.96.100 ?
      Not your pfSense, right ?

      What was the DNS IP your PC got from pfSense (see the ipconfig /all command shown above )?
      More something like 192.168.1.1, right ? wrong ?

      edit : anyway, your PC got an answer : 192.0.0.88 so that must be Google. That's all a browser needs to connect to 'Google : that IP.
      The thing is : that IP is, IMHO, not Google ...

      Edit : and where are the logs ??

          That's a NordVPN DNS server. So your client might be using a VPN dircetly. Or you might have added it to pfSense etc....

              If nord is involved yeah I would say your dns is borked.. They started intercepting a while back, per other threads..

              That 103 address is a packethub IP.. But as so eloquently stated by @Gertjan 192.0.0.88 is not google.. hehehe, still giggling.. Love it!

                  Wasn't NordVPN intercepting 'all DNS' requests as seen in some recent forum threads ??
                  And now it is replying with Pure-BS ?!

                    @Gertjan yeah they were intercepting all dns from test had one user do, they were getting answer from 1.2.3.4, which sure and the hell is not providing dns.. So right there is smoking gun that interception and redirection is happening.

                    I wouldn't trust those idiots with anything.. VPN service intercepting something as basic as dns is not what they are suppose to be about.. Most people use a vpn to make sure their isp isn't seeing or intercepting their dns..

                        that points to a problem to be honest, is that not pfsense? pfsense should always be able to resolve its own name.

                          That is your pfSense LAN IP, right ?

                          And no answer came back ?

                          Can you post your LAN firewall rules ?

                          Unbound is listening on the LAN interface ?

                              Thanks.
                              I've added to the mix : queues and scheduled rules ....

                              I hope Google translate will do the job :

                              Backup your pfSense config. So from now on, you can go back the what you have right now.

                              Then : console menu option 4 - Factory defaults.

                              From now on, you have to respect one rule : change only the admin password. Change nothing else.
                              I make a special note for DNS : don't remove add change anything. Out of thne box, the resolver works just fine.

                              Do some testing and conclude that everything works fine.

                              Now, you have a choix :
                              Import the backed up config. And then goto here, as you're back to square one.
                              Or : add your own changes one by one, each step separated by extensive testing.
                              As soon as you detect that something 'fails', you know where it went wrong.

                              No "help me" PM's please. Use the forum, the community will thank you.
