      You are right, reach is actually 0

      I used pfSense's packet capture, and pfSense (192.168.168.254) will get a reasoanble answer from the NTP server (192.168.168.218).
      I am not an NTP expert but looks good to me...

        Nothing I'm aware of. Is pfSense avble to reach that device genarally, ping it?

        Do you see responses coming back to pfSense if you pcap for it or check the state?

          Yes it's pingable and pfSense gets back a (reasonable) response, see post above

            Well that is saying the clock is not synchronized, so yeah don't think pfsense would consider that a valid time source to sync too.

            edit: oh that was your client.. Doh.. let me look a bit closer.. your getting zero for reach?

                Thanks, but the "clock unsynchronized" message is part of the packet from pfSense (.254) to the NTP server (.218)?

                192.168.168.254.123 > 192.168.168.218.123: [udp sum ok] NTPv4, Client, length 48
                Leap indicator: clock unsynchronized (192), Stratum 0 (unspecified), poll 6 (64s), precision -23
                    [...]
                

                The answer is

                192.168.168.218.123 > 192.168.168.254.123: [udp sum ok] NTPv4, Server, length 48
                Leap indicator:  (0), Stratum 1 (primary reference), poll 0 (1s), precision -18
                    [...]
                

                Or am I totally wrong?

                  @conover yeah I caught that was the client - see my edit ;)

                    yes,
                    "Status / NTP" says Reach 0 for that NTP server (.218),
                    RefID is ".INIT."

                      Interesting, explicitly using ntpdate works with that NTP server:

                        @conover do you have it set as peer vs server? I can duplicate your issue if set mine to peer vs server

                          @johnpoz Thanks! It was set to server in 23.05 config and it is unchanged. But out of curiosity I also tried "peer" with no change.

                            @conover so you flipped it to peer, and then you flipped it back?

                              Yes, exactly (and restarted the service after each switch to be sure)

                              What does your xml show? And your conf file

                              Which XML do you mean?

                              The conf file looks pretty much the same (but no minpoll) :

                                @conover that is odd for sure, clearly from you sniff looks like you got an answer..

                                I can't seem to duplicate it though, when on peer it never works, but set server and bam start seeing reach count up.

                                For grins! could you remove the pool and just point to your server..

                                  yes, absolutely, also ntpdate works and synchronizes the clock with the server

                                  For grins! could you remove the pool and just point to your server..

                                  same result

                                  Is there an easy way to go back to 23.05? I would try if it's still working with that. If yes, it must be something with the 23.09 release....

                                    If you installed ZFS there will be a BE snap from before the upgrade you can roll back to.

                                      @conover said in 23.09 Local NTP server "unrechable" (worked with 23.05.1):

                                      it must be something with the 23.09 release....

                                      While I don't deny you have something wrong - I don't see how its something wrong with 23.09 in general. I point to a local ntp server, I am running 23.09 and not having any issues.

                                      What is odd, is your status shows type s, pretty sure that means peer (symmetric).. while u would be normal if just pointing to a server - see mine from above shows u.. If I set mine to peer, it doesn't work and it changes to s, and if I look in the xml (do a backup download of your whole config) then open in your fav text editor and look for ntpd

                                      As soon as change mine back to server, it starts working right away. See how the reach started counting and my type is u not s

                                        @johnpoz Thanks for your ongoing support!

                                        Not saying it's something wrong generally in 23.09 but at least something specific :-) Either in combination with my NTP server or something went wrong during the upgrade.

                                        Went back to 23.05.01 and everything is OK again

                                        After being back to 23.09 same as before...

                                        The flag "u" and "s" appears randomly or changes after some time, currently it is set to "u":
