      I am having issues with my TOTP and I am noticing that the time of my pfsense is off by two minutes from the time of my client. I've configured both the pfsense and my client with the same ntp server: 0.north-america.pool.ntp.org but the pfsense is still off by two minutes.

        Is the pfsense actually syncing to ntp? What does the status of your ntp service show in pfsense?

            Try using:-

            0.pool.ntp.org to 3.pool.ntp.org

            Does it then sync ?

            "NTP will only sync if a majority of the servers agree on the time. For best results you should configure between 3 and 5 servers (NTP support pages recommend at least 4 or 5), or a pool. If only one server is configured, it will be believed, and if 2 servers are configured and they disagree, neither will be believed. Options:
            Prefer - NTP should favor the use of this server more than all others.
            No Select - NTP should not use this server for time, but stats for this server will be collected and displayed.
            Is a Pool - this entry is a pool of NTP servers and not a single address. This is assumed for *.pool.ntp.org."

              Well that is not working since its not even resolving any hosts in the pool. So it doesn't even know to ask any ntp server for time.

              See how I have a placeholder, and then IPs listed under that.

              I would validate that pfsense is able to resolve.. You can use the dns lookup tool under diag to check if pfsense can resolve that FQDN.. See example below

                  Ok so your resolving, but ntp not able to reach or is not resolving? Place a specific IP in there vs FQDN.

                  What do you have listed for interface that ntp is listening on? There was a recent there were a user was seeing a problem that ntp could not query unless they selected the wan interface. Even though that should not be required, unless you had maybe messed with your outbound nat.

                  Are you trying to force all traffic through a vpn? your doing something odd with pfsense dns for sure since the only IP listed in pfsense for using the unbound resolver is the loopback, like you see in my output. But your also listing opendns.

                    @johnpoz I am not sure why 0.north-america.pool.ntp.org was cut off in the Status/NTP section but it was configured correctly in the NTP config and it resolves perfectly fine.

                        These are the results when I put the IP addresses directly in. Where do I find out what interface NTP is listening on?

                          Here's a link to my thread (that johnpoz mentioned) on the same problem:

                          https://forum.netgate.com/topic/131506/ntp-not-working-solved-mostly

                          For me, I have to have WAN selected under Services > NTP in the Interfaces section. I've been utterly unable to find any reason for this since it shouldn't be necessary.

                              I don't like having my WAN selected for NTP to listen to. But, since that's the only way I've found to be able to get NTP to run, I guess I have to live with it.

                                Does it now work ?

                                You both shouldn't need to have it listening on the WAN interface.

                                  @johnpoz so it looks like my outbound NAT is manually configured. How will this prevent NTP from syncing?

                                    NTP will ONLY run on my SG-4860 if WAN is selected to listen to (the gory details of everything I've tried are in the thread I referenced, above). I agree that the WAN shouldn't be necessary. But, for no reason I can come up with, it turns out to be necessary in my case.

                                    Looking over some of brunovic's other posts, it looks like he's using a VPN. I am, too. It's possible that's a relationship, but I just don't see why using a VPN might interfere with NTP.

                                      @beremonavabi I use a VPN for remote access into my network but not for outbound traffic. Is that how you are using it?

                                          @brunovic I've got OpenVPN clients running on my pfSense box to my VPN provider (AirVPN). I've also got a server running on it so our phones can use the VPN.
