        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

          @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

                              @ARAMP1 ok the only thing that looks odd is your restrict 192.168.10.120 that is not really a network that is a host address. The network with /24 would be 192.168.10.0

                              After seeing yours noticed mine wasn't even listed... I removed mine completely because to be honest that is for clients wanting to talk to pfsense as their server. So you shouldn't even need that.

                              I would remove it, but that would be really crazy if that was the issue.

                              Nothing is there that makes any sense to why it wouldn't be working that I am seeing..

                              So you have no native network on the ix1 interface.. Only vlans.. I take it ix1.10 is your 192.168.10 interface..

                                @johnpoz I'm not following when you say "I would remove it". What would/did you remove?

                                I have a native network on the ix1 interface but it's not enabled.

                                    One other small note:

                                    Anyone remember that authentication ticket that has been open for years with NTP, someone named Mathew fixed it and has a pull in the system no one has reviewed it yet, it fixed the GUI issue and also some other items with the pool for NTP.

                                    @MatthewA1 @LamaZ

                                    Did this github ever get merged?

                                          The PR is against master so that would be 2.8-dev at this point.

                                            @stephenw10 Should I have opened the PR against a branch for 2.7 when I first opened it instead of master? As of now, it is in the correct place though right?
