      well, there are 3 or 4 post addressing that issue and a few people hopped on each thread.

      Lets see out of how many 1000's and 10s of 1000's of pfsense deployments? I am on here way too much, and I am not seeing these posts..

      There may well be a bug/issue - but without some actual specifics of the users setup to find something common, users chiming in with me too.. Are of zero help.. For all we know they have some simple misconfiguration.. Like wrong IP address of their ntp server for gosh sake..

      the only way to track down what your problem is with info.. Not I play with some stuff and couldn't get it to work ;)

        @johnpoz guess, all infos can be found here: https://forum.netgate.com/topic/184170/23-09-local-ntp-server-unrechable-worked-with-23-05-1

        another thread (besides this one) is here (in German) https://forum.netgate.com/post/1137308

          @ARAMP1 said in NTP Issue:

          I just played around a bit with this and couldn't get it to work.

          And what did you play with? Can we see your config? Can we see your ntp log? Can we see a simple sniff, you say it works via just using ntp out on the internet. Can we see sniff of that working?

          I have been running a pi as my ntp server via a gps hat and yeah it would use pps as the source. For years, multiple versions of pfsense back to pre + days, And currently have a 2.7.2 pfsense as well as 23.09.1 and not having any issues syncing with my pi ntp server.

          Are you trying to use auth? To your ntp - you say none of your other devices have any issues syncing with your ntp server? Can we see this output?

          example

          $ ntpq
          ntpq> pe
               remote           refid      st t when poll reach   delay   offset  jitter
          ==============================================================================
          *ntp.home.arpa   .PPS.            1 u   57  128  377    1.542   +0.376   0.193
          ntpq>
          

          My windows box sync with my pi, here is pfsense

          [23.09.1-RELEASE][admin@sg4860.home.arpa]/root: ntpq
          ntpq> pe
               remote           refid      st t when poll reach   delay   offset  jitter
          ==============================================================================
          *ntp.home.arpa   .PPS.            1 u  137  512  377    0.449   -0.741   0.189
          ntpq> 
          

          What are you using as your ntp server, ntpsec, chrony, just the plain jane ntp from ntp.org?

          If there was some inherent bug/issue with ntp sync then you would think there would be many posts about it.. Since there does not seem to be - this points to something unique in your setup that is problematic, etc..

          here is my settings, where 192.168.3.32 is my pi ntp box.. Which is running ntpsec

          ntp.jpg

          Here is my pi output

          pi@pi-ntp:~ $ ntpq
          ntpq> pe
               remote                                   refid      st t when poll reach   delay   offset   jitter

          edit: my 2.7.2 box was off, just booted it - and can see right away that it can talk to my ntp server.. as reach is counting up

          272.jpg

          edit2: just booted my 24.03 and pointed it to my ntp server and bam its talking to it as you can see reach is counting up as well

          2403.jpg

          here is a pcap of pfsense 3.253 talking to the ntp server 3.32

          pcap.jpg

          Oh, I'd bet it's 100% user error, just want to figure out where.

          It appears I have it set up like yours.

          I'm using one of those chinese ebay boxes. I've had it running fine in pfSense for about 3 years now.

          Here are the logs related to the server at 192.168.10.120

            @ARAMP1 one thing I see as different is why are you pointing to multiple pools that are really the same? You run your own ntp server, while sure it should point to some others vs just its gps time.. pfsense really has litte need other than just pointing to your one ntp server that you are running.

            Why can it not talk to any of those other ntp servers either.. All of those other ones should be available via wan, that it is seems it talking to the 128.138.141.172 box.

            You cut off your config - are you trying to do auth?

            If you want to add more later - sure but for troubleshooting I would just point to your 1 local server.. And then sniff do you see an answer?

            Can we see your other devices that are syncing off this local server? For example I already showed my windows box syncing - here is one of my switches using it

            sg300-28#sho sntp status
            
            Clock is synchronized, stratum 1, reference is 192.168.3.32, unicast
            
            Unicast servers:
            
            Server            : 192.168.3.32
              Source          : Static
              Stratum         : 1

              Offset          : 347.3516068 mSec
              Delay           : -1000 mSec
            

            here is my nas, and printer all pointing to my local ntp - showing working

            printer.jpg

            nas.jpg

            For troubleshooting - I would set the only interface on to be the one interface where your ntp server is. And I would sniff the traffic to validate you see it sending to it, and getting a response on its own accord, not with the ntpdate command, etc.

            Here is my unifi controller setting, and showing that one of the AP is sync'd etc

            unifi.jpg

            edit: oh my nas is using old name, which still resolves - but should change that to home.arpa vs local.lan

            What are you running for your ntp server? ntp, ntpsec, chrony?

            edit2: that you are only able to talk to 1 of the many many ntp servers your pointing to is very odd to me.. If there was something wrong with pfsense, why is talking to anything. If there was some disconnect between pfsense and your ntp server, why is it not talking to all the other servers your pointing to?

            Clearly something is amiss - figuring out what it is the puzzle needed to be solved.

              Appreciate the reply.

              I'm not doing NTPv3 authentication.

              I actually originally had it only pointing to my local server, but when it started acting up, I started adding. I assumed that since I checked "prefer" it would default to that one if it started working.

              Here's what I get when I delete all the others.

              NTP 5.jpg

              I can point anything on the network to my NTP and it seems to work. Here's the windows 10 machine I'm on now.

              Sync with NTP.jpg

              Show NTP.jpg

              Here's a TrueNAS server that I just pointed it to.

              NTP Truenas.jpg

              Really, I only need it for my Blue Iris machine because I want all of my security cameras synced. Other than that, it's just nice to have it working.

              Forgive me, but I'm not sure how do do the ole sniff.

                @ARAMP1 the sniff would be just packet capture under the diagnostic menu.. You can have it only capture the ntp from your IP of your ntp server and port 123.

                Select the interface used to talk to your ntp server, assuming that is your lan interface.

                You can then download that capture and we can look at it with say wireshark.

                The info from your nas is good.. what IP is your nas on, I assume its on this same 192.168.10 network.

                edit: don't camera's sync their time via ipc?

                nvr.jpg

                I don't have ntp setup on my cameras - they sync with the nvr via ipc.. But blue iris could be different for sure. The nvr syncs directly with my ntp server.. Why wouldn't you sync your blue iris and your cameras directly with your ntp server? vs pfsense?

                That being said - pfsense for sure should be able to sync with your ntp server.. But if you can just sync your camera stuff with your ntp server, then the pfsense time sync isn't as critical, etc. And can figure out what is going on it with it without having to worry about your camera time being off, etc.

                  My windows machine is on the 10.10.50 network and that truenas machine is on the 192.168.60 network but I have rules on each of those VLANs to access 192.168.10.120 for NTP (the 192.168.10 network is my management network with all my switches, access points, etc).

                  For cameras, here's the rules I have in place.

                    @ARAMP1 well that is interesting.. So the devices on different networks sync fine - but the pfsense on the same network is not able to reach it??

                    Your not doing anything with ethernet filtering, nor any floating rules for outbound filtering?

                    As a test - your truenas can act as ntp server I would assume.. Can you point pfsense to it?

                    Example - just pointed pfsense to my nas.

                    nasntp.jpg

                    notice it shows the 9.10 address of my nas, and it shows its ref as my pi ntp server the 3.32 IP

                        I take it that is your pfsense IP at 10.1 - can you download that and attach the pcap.. For example - here is pcap I did earlier

                        packetcapture-igb3-20240602095409.pcap

                          @ARAMP1 well that is interesting.. So the devices on different networks sync fine - but the pfsense on the same network is not able to reach it??

                          Your not doing anything with ethernet filtering, nor any floating rules for outbound filtering?

                          As a test - your truenas can act as ntp server I would assume.. Can you point pfsense to it?

                          Example - just pointed pfsense to my nas.

                          nasntp.jpg

                          notice it shows the 9.10 address of my nas, and it shows its ref as my pi ntp server the 3.32 IP

                          Just tried pointing it to a couple truenas servers I have on different VLANs. Both are Unreach/Pending.

                          The floating rules I have in place only have to do with CoDel traffic limiter and pfBlocker.

                                  Something with the DNS server? Here's my setup.

                                    @ARAMP1 no it wouldn't have anything to do with dns, because your pointing to an IP for the server.

                                    I would think that ref ID would point to the IP your asking.. see in mine it shows my 192.168.3.32?

                                    It might be like that because it has never gotten an answer? So it has no ref as of yet?

                                    From your sniff you get an answer, so why would ntp think it can not reach that server?

                                      @ARAMP1 can you turn off ntp and validate nothing is listening on 123..

                                      example

                                      grep.jpg

                                        I've still pointed clients at 192.168.10.120 directly, so that would still show something listening on port 123, right?

                                          @ARAMP1 not clicked to not enable it

                                          As you see when I disable it nothing is listening on 123

                                          Also can you one you enable it again, post up your ntpd.conf
