      Add both to the following to the suppress list and run a "Force Reload - DNSBL"

      www.msftncsi.com
      msftncsi.com

      You can run the following to see if a domain is listed:

      grep "msftncsi.com" /var/unbound/pfb_dnsbl.conf
      grep "msftncsi.com" /var/db/pfblockerng/dnsbl/*.txt
      grep "msftncsi.com" /var/db/pfblockerng/dnsblorig/*

        @Deadpool:

        is it possible to whitelist with placeholders?

        for example whitelist video.domain.com*
        or how would i do that correctly?

        because i have a domain where videos are not playable and it looks like this -> video.domain.com/abc=43 and the id's always change.

        Wildcards don't work in DNSBL Suppression. Needs to be an exact match…

          Only the last command gave an output:```
          /var/db/pfblockerng/dnsblorig/ADs_someone.orig:127.0.0.1 msftncsi.com
          /var/db/pfblockerng/dnsblorig/ADs_someone.orig:127.0.0.1 www.msftncsi.com

            maybe you need to clear the DNS cache on windows side

            2.4.5-RELEASE-p1 (amd64)
            Intel Core2 Quad CPU Q8400 @ 2.66GHz 8GB
            Backup 0.5_5, Bandwidthd 0.7.4_4, Cron 0.3.7_5, pfBlockerNG-devel 3.0.0_16, Status_Traffic_Totals 2.3.1_1, System_Patches 1.2_5

              Hi Xmicks,

              The three commands will show:

              First grep cmd:  If a domain is listed in the DNSBL Blocklist.
              Second grep  :  This will show which Feed has a Blocked Domain
              Thirds grep    : These are the original files from the Feed…

              So you don't have any reference to  msftncsi.com  in DNSBL....

              If its still blocked, clear your browser and OS cache... If you ping it and its still getting the DNSBL IP, then its probably still in your cache....

              Can use this to clear the cache from Chrome :  chrome://net-internals/#dns

                Now the domains are surpressed! Don't know why it suddenly worked, because I already had both www.msftncsi.com and msftncsi.com listed. And had forced reload multiple times before.

                Nonetheless it workes now  :D

                  ok Next time you have some more tools to work with :)  Any other issues let me know..

                    Alright, thanks both for the help! :)

                    Well there is one thing. Everytime I open a webpage on the pfsense forum I get a 403 error(see image). I then have to quickly reload that same webpage again to open it. If I wait to long(+-3 seconds) i get the same 403 error. Is this caused by pfBlockerNG?

                    pfBlocker is the only package I have installed at the moment. If I remember it correctly it started when I installed pfBlocker, but it might as wel be something else.

                    ![403 error.PNG](/public/imported_attachments/1/403 error.PNG)
                    ![403 error.PNG_thumb](/public/imported_attachments/1/403 error.PNG_thumb)

                      I can't find the thread, but others have noticed this also… Don't think it has anything to do with the package, as I have seen it myself on my mobile while away from my home. However, I haven't seen the issue in a few weeks...

                        thanks your your feedback

                        could this be something to add in a future version of pfBlocker? does it make sense anyway?

                          Hi - I'm having some trouble with pfBlockerNG updates when DNSBL is enabled. The update process spikes my CPU to 100% for more than an a hour. I've tried manual updates as well as CRON, but no success in completing the updates.  Any thoughts?

                              I'm running an Intel(R) Celeron(R) CPU N2930 @ 1.83GHz 4 CPUs: 1 package(s) x 4 core(s). I've 8GB ram and 40Gb SDD.

                              I do have IP4V De-Dupe currently enabled with most of the Top 20 spammer countries selected. I've selected the two default DNSBL EasyList feeds and Top1M Alex sites. Within EasyList I've selected all categories and chosen Unbound as the list action.

                              Happy to tweak these settings or test any other recommendation.

                              Thanks!

                                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 :-(

                                This is an issue with the pfSense pkg_edit.php code… I have been discussing a fix with the Devs... Hope to get it resolved shortly...

                                    have you force reloaded on the Update Tab?

                                    I most definitely did.  The exclusion list has been sitting in there for months and never worked.  I just got motivated to look into why it's not working today.

                                    What kind of Domain are you suppressing?

                                    Can you grep for it:

                                    grep "example.com" /var/db/pfblockerng/dnsbl/*.txt
                                    grep "example.com" /var/db/pfblockerng/dnsblalias/*.txt
                                    

                                    Thanks for the response.  Sorry it took awhile, I was out on travel and just got back.

                                    OK… I think it might be working but I just have to pay closer attention to it.  The issue I was having was with the Walgreens site.  Whenever I would refill a prescription, it would hang and a log would get written in the dnsbl alerts.  I think the issue is me not adding all the domains that it got redirected to-to that whitelist.

                                    I ended up trying one of the domains that was blocked previously but whitelisted, and it seemed to let me through.  So.....I think it's an issue with whitelisting the redirects and not with pfblocker or dnsbl itself.

                                      Hi - I'm having some trouble with pfBlockerNG updates when DNSBL is enabled. The update process spikes my CPU to 100% for more than an a hour. I've tried manual updates as well as CRON, but no success in completing the updates.  Any thoughts?

                                        I have multiple pfsense firewalls at multiple locations, on various versions. My newest ones are on 2.3.1 release p1, I see there is now a p5. My problem with pfBlocker is that on this newer version, pfblocker is on version 2.0.17 whereas I have an older version of pfsense, version 2.2.5 that has pfblocker 2.0.2. The problem I am having is that the newer pfsense is not offering an update to pfblocker, and I am comparing versions due to a problem with the DNSBL allowing me to sites on the newer pfblocker with the older pfsense but blocking my clients on the newer pfsense with the older pfblocker. Why would it not offer an update to the package for pfblocker?

                                          I am not actively updating the package for the 2.2.x branch… Just not enough time in the day to support multiple branches...  2.0.17 is only available for 2.3.x.  If you are not seeing the new version in the 2.3.x branch, then try to execute a "pkg update -f" command... if your still having issues with that, then try to post in the pfSense "Installation and Upgrade" Threads and see if one of the Devs might have some answers for you...

                                            Okay, that did not work. So the newer pfblocker versions are only available for the older pfsense versions? For your records as well, we see all of our newer pfsense versions not properly logging the DNSBL alerts as well. Maybe we will back date our pfsense versions as the pfblocker is our most important tool.
