        @swampland7794 well clearly you didn't set it to ignore local.. Or it would of never tried asking 127.0.0.1

        ignorelocal.jpg

        When you changed that drop down to use remote, ignore local did you scroll to the bottom and hit save? Did you see it say

        applied.jpg

        You prob also want to uncheck that let wan override dns settings - see my screenshot

          @johnpoz I would would send you a screenshot, but I can't figure out how to upload one from Android. That's what my options are set to under general settings. It shouldn't use 127.0.0.1 since that's the loopback address.

            Not if you set it to use remote and ignore local.. As to posting a screen shot use this button

            post.jpg

            Or you could use this to post some external image

                  @swampland7794 well when you do your dns lookup now under diagnostics what do you see.. From your screenshot before that IP answered - but looks like it couldn't lookup google.. But showed a 0 ms response time..

                  Query something you know your local dns has a record for, or can lookup.. do a simple query to it with your fav tool other than pfsense for example..

                    seems unlikely that a new user would be doing that

                    True, but you never know, if you don't ask.
                    Take my wife for example. Give her a piece of tech and she pokes buttons "learning". then in a few days hands the device back to me, and says "it is broken, can you make it go". First question is always, "so what did you poke?".

                    Maybe he setup some soft of pfblocker rules that are doing it?

                    not likely. Although there was a report a while back, that one of the "lists" had added 9.9.9.9 (in error) and anyone using that list, with that DNS suddenly didn't resolve.

                    in the very first post,

                    @swampland7794 said in Pfsense and network DNS:

                    I have a mini server with technitium DNS server on it and I changed pfsense general settings to have this device as the only DNS server,

                    I noticed that all of my devices are using my DNS server except pfsense itself.

                    The IP address for DNS at 203.x.y.z doesn't seem like his local "have a mini server with technitium DNS server"

                    that address seems more like

                    inetnum:        203.128.32.0 - 203.128.63.255

                      @johnpoz I chose Google and my docker server.

                        @jrey I manually set my subnet to something obscure like 203.128.45.0/24 which puts my pfsense box at 203.128.45.1 and my mini server at 203.128.45.2

                          randomly or do you own the address space?

                              Yeah NOT a good idea at all, while technically you can do it - its a horrible idea to do that.. that space is owned by

                              inetnum:        203.128.32.0 - 203.128.63.255

                              Whatever your doing your query to refused it.. You would have to look to the acl you have set on that NS your sending the queries too.

                                  @jrey yeah its horrible practice to just pull public space out of thin air and use it locally.. You have all of rfc1918 to use, there is zero reason to use public space that you do not own.

                                      @swampland7794 I changed the DNS address to 1.1.1.1 and changed the subnet... I messed my home network and I don't have access. I'll fix it when I get home tonight and we'll see if that resolved my issue.
