      @javen That is definitely not the normal. The unbound resolver should start automatically like any other service on the box.

      What packages are installed on your box? PfBlockerNG (devel) perhaps? That interacts quite a lot with Unbound, and can cause issues if it not configured correctly.

      If you have upgraded through pfSense versions you might be better of taking a config backup, and then get the restore image for the SG-3100 from support and really “reset” it :-) The facorty reset in the Shell/GUI only removes your config files and currently installed packages. If - through versions/upgrades or powerfailures - you have had system service files for unbound added or modified or corrupted, they will not be cleaned unless you get the restore image from support.

      Love the no fuss of using the official appliances :-)

        I have had pfBlockerNG installed in the past before I figured out that unbound was the problem and restarting the service after every reboot fixed the problem.
        Currently I have no packages installed. I ran Diagnostics > Factory Defaults > Factory Reset from the GUI.

        restore image for the SG-3100 from support

        I've re-imaged the sg3100 a few times in the past and it didn't resolve the issue. Once in June 2020 shortly after getting it, and again in August 2020 using pfSense-netgate-SG-3100-recover-2.4.5-RELEASE-p1-armv6.img.gz
        I haven't re-imaged since pfSense Plus.

        I'll re-image it one more time and see if the issue persists.

          Also, searching for failed to prime trust anchor -- DNSKEY rrset is not secure . DNSKEY IN pointed me to a Netgate Forums post by gjaltemba on 2015-03-20 with the title "Failed to prime trust anchor".

          For which the solution was to uncheck Services > DNS Resolver > General Settings > General DNS Resolver Options > DNSSEC.

          Disabling the DNS Resolver's DNSSEC support works, and the DNS Resolver seems to run correctly after rebooting the router. No manual unbound service restart required. Getting closer...

            Welp, I guess I get to re-flash the SG-3100 a little sooner than planned.

            After enabling a few more settings in the DNS Resolver, I'm now no longer able to reach the SG-3100 on my network.

            DNS Resolver
            	DNSSEC
            		Enable DNSSEC Support = unchecked (must be unchecked)
            	DNS Query Forwarding
            		Enable Forwarding Mode = checked (doesn't matter)
            

            Then I checked these are rebooted:

            DNS Resolver
            	DNS Query Forwarding
            		Use SSL/TLS for outgoing DNS Queries to Forwarding Servers = checked
            
            	DHCP Registration
            		Register DHCP leases in the DNS Resolver = checked
            	Static DHCP
            		Register DHCP static mappings in the DNS Resolver = checked
            

            Enabling the last 3 settings made the router inaccessible. :(

              @javen The “Register DHCP leases in DNS” must be unchecked in the current implementation of Unbound in pfSense. This has been a long standing issue…
              The static DHCP clients registration is not an issue

              Otherwise the DNS resolver will reload every time a DHCP client gets an IP. This could very likely be your problem at startup. If you have a bunch af clients getting an IP when the DHCP server is up, it could likely prevent Unbound from actually starting for quite a while because of sustained reloads.

                This :

                failed to prime trust anchor -- DNSKEY rrset is not secure . DNSKEY IN

                is surely related to this :

                ffad8d3c-abc1-4be6-9fbe-515bfc862e9a-image.png

                the system was thrown back in the past 4 weeks.

                For DNSSEC to work correctly, the time on your pfSense must be correct. Ok if it is out of sync a second or so. 4 weeks is a disaster.

                What happens if you :
                Make a backup of your settings.
                Diagnostics > Factory Defaults > Factory Reset
                After reboot, do not (like not at all) import your settings back in.
                Make a minimal WAN LAN done setup. Ok the change the password - nothing more.
                Now the system should be good. Time should be good. The resolver is resolving, not forwarding to 1.1.1.1 etc

                if the power is out longer than my UPS's battery can last.

                When this happens, pfSense did a clean shut down by itself, right ?
                Rebooting has to be done by removing the power shortly.

                Have a look at the console interface while the system is booting, look for warning or error messages.

                Edit : and where are the logs ??

                  I re-imaged the sg3100, installed to mmcds0 and then re-imaged to ada0 (the 32 GB M.2 drive I included in my sg3100 order).

                  I went through the 9-step wizard and still got the same behavior: DNS did not work after rebooting.
                  I didn't bother backing up my config or trying to restore a config--I want uncustomized, vanilla pfsense for now.

                  Disabling DNSSEC fixed the issue as before. I'm still getting teleported between Jan 20 2022 and Dec 27 2031.
                  Even when DNS is working, if I connect to the sg3100 via USB shell access, after rebooting:

                  [21.05.2-RELEASE][root@sg3100.localdomain]/root: date
                  Sat Dec 27 11:08:59 PST 2031
                  

                  It seems like the system only gets the correct date when ntpd is able to reach the external ntp servers, which also requires having the dns interface working.

                  Of course I'm getting errors about bad certificates or keys during boot, because most keys have a validity period, with a validity window that probably doesn't extend to 2031. Shouldn't the system be able to keep its time from the last boot, and then correct any drift (hopefully by no more than a few seconds) the next time it fetches the current time from an ntp server? The coin cell battery in the sg3100 is +2.9V with the correct polarity. It doesn't make sense to me why the time resets every time the system reboots, and only is correct after the unbound has launched and the NTP service fetches the time from ntp.org. Every Linux system I have remember what time it is after rebooting before they connect to the network.

                    @javen Good diagnostics - so the time skew is definitively your real problem here.

                    Does your pfSense itself not get DNS servers from your WAN provider (via DHCP)?
                    You should make sure to setup your pfSense (itself) to access DNS either by default via your WAN DNS, or at least to fall back to those if unbound resolver goes offline.

                    You could fix your issue with using the override DNS feature on the System -> general settings page.

                    That way DNS will work for pfSense right away, and NTP will come up and time will be correctly set on the appliance.

                    EDIT: But I agree it's very weird that it does not keep time over a power cycle....

                      Except the ones that have a broken on board RTC ... ;)
                      Even iff the battery is still ok, change it.
                      Also : boot with the console - and goto the 'bios' : the clock will be chown. Maybe teher are some RTC settings ?? ( I don't own a 3100).
                      ntpd can be used, though : instead of using a host name like "fr.pool.ntp.org", you can use an IP.

                      If these still exist, they are meant to be used by the 'stupid' ISP routers that have nothing more as a simple forwarder.
                      pfSense is equipped with the far more superior "resolver".

                      I'm pretty sure there is no "unbound" issue what so ever, it's a 'time' issue.
                      I'm crossing my fingers for you, as 'mI hope the RTC device isn't broken.

                        @javen Several of us are experiencing and have complained about this issue. Here is my thread on it. I gave up trying to fix it for now so still have to restart unbound after every reboot. Here is a pointer to my thread which may have some additional info for you…
