      If you are in a multi-segmented Lan network, there is a ☑ in the DNSBL tab to auto create a Floating allow rule for the selected Lan networks.

        That is already checked and created

          I have added all lists on my apu.
          Now my unbound is very slow. It takes more than 800ms to resolve a hostname.
          The flicker.conf list is about 60mb.
          I have increased some values like Message Cache Size and Number of Hosts to Cache. 50mb and 100000. But it is still so sloooow.
          Any ideas?
          Thank you

            Ensure that your LAN devices can ping the DNSBL VIP, and also that they can browse to the DNSBL VIP and get the 1x1 pix.  If any of those two tests fail, you will see slowness as the browser is timing out waiting for the DNS resolution to the blocked Domains.

              Thats works fine.
              I tested the dns resolution time in the Diagnostic menu.
              With top I can see that unbound takes a lot of cpu for some time.

                Is the Resolver in "Forwarder" or "Resolver" mode?

                What DNS settings are defined in the pfSense General Tab? As these settings are used by the pfSense box itself…

                When testing the ping/browse to the DNSBL VIP, do that from the LAN clients and not from pfSense itself.

                If you're in a multi-segmented LAN, ensure to use the 'DNSBL Permit Rule' option in the DNSBL Tab. Also clear your Browser/OS cache.

                  Resolver Mode.
                  No multi segmented LAN.
                  VIP is tested from remote.
                  I tested a dns resolution like www.IBM.com on pfsense box.
                  The slow network is reproducible on many devices.
                  Maybe there is a mistake in my config which unbound makes that slow.

                    Unfortunately not 100% sure of what fixed it, but the DNSBL alerts are current. On to the next…

                      Ive just noticed an annoying bug when pressing save on the Firewall/pfBlockerNG/Edit/IPv4 page if there are any errors all your data gets wiped out :-(

                      Can you please leave the data so if can be corrected?

                      FYI, this bug was fixed by the following pfSense commit for pkg_edit.php:
                      https://github.com/pfsense/pfsense/commit/a654d899cd5d288501fea1ec52dba2e3f0e479ba

                      Its in the pfSense Dev version and will be in the next pfSense 2.3.2 release.

                          I think i found out, why my network is so slow and unresponseful sometimes.
                          The Unbound seems to restart pretty often :(

                            Hi Luke,

                            When 2.3 was in testing, I attempted to switch to NGINX; however, ran into issues on DNSBL logging for HTTPS alerts. Lighttpd has an error-conditional-log that contains some details that the pkg uses to provide some Alert details for HTTPS alerts. With NGINX, when the browser drops the connection to the DNSBL webserver due the incorrect Certificate provided, no other logging is completed by NGINX. I managed to get the Devs to add LUA support to NGINX, but there were issues with OpenSSL at the time that prevented further testing. I may revisit this as time permits, but so far, there hasn't been any issues with both NGINX and Lighttpd running at the same time.

                              Do you have DHCP Registration enabled in the Resolver? Maybe try it without those two checkboxes… Are you running it in Resover or Forwarder mode? Is DNSSEC enabled?

                                  I am running the DNS in Resolver Mode. Forwarding is disabled. DNSSEC is enabled; but was disabled before and i had the same problems.
                                  Yes, i have both boxes checked. (I need this).
                                  I can try to disable the checkboxes. This morning my whole network had problems, because the Unbound stopped and did not restart.

                                    I think i found out, why my network is so slow and unresponseful sometimes.
                                    The Unbound seems to restart pretty often

                                    Do you have DHCP Registration enabled in the Resolver? Maybe try it without those two checkboxes… Are you running it in Resover or Forwarder mode? Is DNSSEC enabled?

                                    I am running the DNS in Resolver Mode. Forwarding is disabled. DNSSEC is enabled; but was disabled before and i had the same problems.
                                    Yes, i have both boxes checked. (I need this).
                                    I can try to disable the checkboxes. This morning my whole network had problems, because the Unbound stopped and did not restart.

                                    There is a serious issue in the unbound service package, you will have to disable DNSBL, so that the line "server:include: /var/unbound/pfb_dnsbl.conf" is removed from Custom Options in the Unbound, to make unbound restart properly when your modem is rebooted or your IPv4/IPv6 WAN IP got renewed.

                                      Check the Resolver.log for additional details… You might have to increase the Log Verbosity to get it to show more details to help diagnose the issue.

                                          So i would have to disable DNSBL every morning after my 24h disconnect, restart unbound and enable DNSBL again…?
                                          I do not really understand this bug, so i think that i am not the eligible person to file an issue.
