      Ok. Unfortunately it doesn't appear to affect the one Chelsio NIC I have available.
      You could add that data point to the other thread.

        It seems to me that this problem no longer appears on version 23.05

          Ah, well that would be a very interesting result. Can anyone else hitting this verify that?

            Running the SG-1100, I have been fighting this problem for a while. I did notice the problem self resolved once I applied all the recommended patches on 23.01 and reboot. I have not gone in and attempted to figure out which one or combo fixes it, with a 1100 it is just too slow 😁

            Curious to know if this solution helps anyone else.

            SG-1100 24.03 (ZFS)

              @defunct78 I'm running 23.01-Release on SG-5100. I'm still plagued with this issue and today I threw up my hands and reverted to port 53 and disabled python mode in both the resolver & pfBlocker.

              I am now watching to see how my system responds.

                The reverse on my side :
                I'm using a 23.01-Release on SG-4100.

                I changed from default resolving to forwarding to quad9 :

                As per instructions :

                cba1360e-083e-49d2-8fe7-71202b362e9d-image.png

                3e765f13-5a5c-4a4e-b7f5-bc8ccb009542-image.png

                and then :

                fed44661-a2b6-438f-a3b4-d3bbd521c150-image.png

                So :
                Python mode (of course)
                DNSSEC : of course not
                Forwarding : that's what this all about : Yes
                TLS : over TLS using port 853.


                04f3535a-9301-4d81-bb00-2aaf183896fe-image.png

                835af205-2728-4c2a-92dc-84838988f974-image.png

                [suspicious mode : ON]
                Look at the number of open TCP connections .... every one of them has an opened TLS state.
                Nice .... but is it ?
                These TLS connections are established by pfSense, not some LAN device.
                To fire of a classic DNS request, using UDP, thousands of code lines are needed to handle the request, answers etc.
                For TLS : that will be hundreds of thousands per connection - and I'm probably still not even close. Because now, it's TCP, far more complex as UDP, and then ... TLS.
                To (re)build a TLS connections, entropy is going through the drain fast.
                I never really found a way to measure available entropy, but what I know : if this one goes to zero, my web multi home server becomes slow. Note that the processor of my web (mail, bind, etc) server uses a quad core Intel(R) Xeon(R) CPU 3Ghz, way more power as my pfSense (a 4100).

                Instead of using the word 'bug' or 'problem' I use this, which permits to to see more clearly what's going on.
                Note that I've switched from resolving mode to forwarding mode over TLS on May 4,2023 @08h00.

                On the other hand : I was forwarding to 1.1.1.1 and friends for a week or two.
                Using TLS of course. I've found no (unbound or DNS) issues what so ever.

                Probably important :
                My IPv4 and IPv6 are, afaik, without issues.

                [suspicious mode : OFF]

                Now, let's wait for thread the subject "Major DNS Bug 23.01 with Quad9 on SSL" to happen.

                No "help me" PM's please. Use the forum, the community will thank you.
                Edit : and where are the logs ??

                  I would argue this is a bug because the same load in 22.05 did not cause any problems even in much larger environments.

                  However has anyone verified that this still happens in 23.05?
                  We have one report saying that after upgrading the problem was solved.

                    @stephenw10

                    I have been using pfSense w/ Unbound configured for DNS over TLS forwarding for years. Recently, it appears that there is a serious issue with the resolver. I get intermittent errors with the following:

                    2023-05-04 10:24:53.905770-05:00 unbound 3136 [3136:2] debug: comm point listen_for_rw 46 0

                    2023-05-04 10:24:53.905719-05:00 unbound 3136 [3136:1] debug: comm point listen_for_rw 48 0
                    2023-05-04 10:24:53.882272-05:00 unbound 3136 [3136:1] debug: the query is using TLS encryption, for an unauthenticated connection
                    2023-05-04 10:24:53.882209-05:00 unbound 3136 [3136:3] debug: the query is using TLS encryption, for an unauthenticated connection
                    2023-05-04 10:24:53.882148-05:00 unbound 3136 [3136:1] debug: serviced send timer

                    Eventually, DNS queires from devices with IPv6 addresses fail causing mobile apps to crash on the connected device. The errors happen with or without pfBlocker DNSBL active

                    I can restart the Unbound service, it will work for a while then the errors return.

                    Also get this now with DNSBL:

                    servicewatchdog_cron.php: The command '/usr/local/sbin/unbound -c /var/unbound/unbound.conf' returned exit code '1', the output was '[1683215282] unbound[54733:0] debug: creating udp4 socket 192.168.246.1 53 [1683215282] unbound[54733:0] error: bind: address already in use [1683215282] unbound[54733:0] fatal error: could not open ports'

                      Are you using Quad9? Are you running 23.01? can you test 23.05?

                        @n0m0fud Have you disabled DNSSEC and/or DNS over TLS as discussed above?

                        re: watchdog and DNSBL...pfBlocker updates and DHCP registrations will restart unbound so watchdog should not try to also start it. It can end up starting twice which is presumably why it is saying the address/port is already in use. Same thing with Suricata/Snort or other services that restart as part of normal behavior.

                        Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                        When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

                          @stephenw10 Running 23.05 forwarding to Cloudflare. Its definitely an IPv6 issue. DNS does not resolve via DNS over TLS on IPv6 Interfaces. I rebooted the router which kills IPv6 for a time after the reboot. Everything worked fine until the IPv6 addresses activated and RADV started. Logs:

                            If you set Unbound to use v4 interfaces for Outbound traffic only does that resolve it?

                              @stephenw10 Only way to do that is manually edit and save the config file. The GUI only allows selection of physical interfaces. Not IP addresses.

                                2023-05-04 11:01:07.981902-05:00 kernel - cannot forward src fe80:2::557:1ce2:51f6:763c, dst 2600:1402:b800:1a::6847:8fd0, nxt 6, rcvif re1, outif re0
                                

                                What has fe80:2::557:1ce2:51f6:763c? It shouldn't be trying to send traffic to a GUA address from LL, it's invalid.

                                What shows in the unbound config for interface binding(s)?

                                  @stephenw10 And restarting the service overrides my manual changes. This used to work fine until about 2 months ago. I know its local DNS as I can manually set the DNS on mobile devices that are showing the issue and the app failure problem goes away.

                                      The GUI only allows selection of physical interfaces. Not IP addresses

                                      Unless it changed in 23.05:

                                      Custom unbound option text is not required for forwarding.

                                      re: cannot forward, is IPv6 working otherwise, from both pfSense and LAN devices? You can ping -6 google.com?

                                      Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                                      When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

                                        @n0m0fud Ping works fine both from LAN device and from pfSense. Enabled the forwarding and let it run for a bit. I have to get on to other things.

                                        Now logs show:

                                          Hmm, interesting. I guess it shows only v6 link local as separate 'interfaces'.
