    @AmosK:

    Is it possible to block a list of dynamic IP's but only specific ports?

    We get a lot of spam H.323 calls originating from AWS (185+ EC2 IP ranges) and DigitalOcean (10+ IP ranges) and others. We'd like to automate the blacklisting but only on port's 1503 and 1720.

    Expert Mode Question: Most of the originator calls are named "unknown" or "cisco" and it would be great to parse those out and block those, though I'm betting that's beyond the scope of pfBlockerNG.

    You can use the "Adv. Inbound Firewall" rule settings to protect only certain ports/Dest IPs etc… I will be adding "Adv. Outbound Firewall" rule settings in the next release. You can also use "Alias" type rules, and manually create the firewall rules to suit more complex setups...

      pfBlockcerNG IPv4-lists: Changes from script: as of 2016-01-18

      Re: https://forum.pfsense.org/index.php?topic=86212.msg510369;topicseen#msg510369

      After perusing the log from the CRON run for pfBlockerNG_import.php script as listed here, it appears that there are a couple changes that might reduce errors that I have documented below.

      Might want to delete the "no access," "discontinued" and "not found" or change status to "off."

      Cheers,

      Todd

        Is it possible to import "Easylist Germany" to "DNSBL Easylist" from AdBlock Plus into pfBlockerNG?

          @BBCan17
          I am having trouble viewing the pfblockerNG alerts.

          On the main index page, I can see (for example) X packets for "pfB_NAmericav4" (I created an inbound rule/alias to block everything inbound on WAN that's not from United States).

          I can see that it blocked 475 packets.

          Clicking on it bring me to the alerts page, which says "Found 29 Alert Entries - Insufficient Firewall Alerts found."

          Why does it only find 29 of the 475 blocked packets?

          I've disabled remote logging for the moment to hopefully eliminate a variable. I've also
          -disenable/re-enable pfbng
          -force update
          -force cron
          -force reload
          -clear logs (from firewall settings tab)

            Hi oddworld19,

            The Alerts Tab takes its info from the pfSense Firewall Log. So if the Firewall log doesn't contain those Alerts, it won't show in the pfBNG Alerts Tab.

            You should disable the "Log Firewall Default Block" option. They are filling your log with unneeded data. You could keep the last two "Bogons" and "Private" as those shouldn't fill your logs as much.

            Then clear your firewall logs. Followed by Disable and Re-Enable of pfBlockerNG to clear the widget packet Counts and see how it goes from there.

            There is a also known issue that I reported to the Devs, but haven't had a response. But that is only specific if you define Ports in the firewall rules. From your post, it doesn't look like you have this issue.

            https://forum.pfsense.org/index.php?topic=99929

            update:

            The Widget has a customization setting to define the "Max packets for Alerts Tab pivot"… Make sure this is set to meet with your requirements.

              The "IPv4 Custom list" seem to be inactive in pfBlockerNG. It worked fine before. I have several IPs I want to block manually in that list but it is not working. Force update and force reload has no effect. The custom list does not appear on the dashboard either. Anyone familiar with this?

                Can you post a screenshot of the Alias? Did you select the "List Action" and define the "Alias" name?

                  Well, the alias name is kind of personal  ;). Contains one space but no "pfBlocker" or "pfB_". List action is "Deny Both".

                    Its probably not going to create the alias if its just a "single space" as the Alias name… Give it a proper name and it should be fine. It can't contain and special or International characters.

                      I renamed it abc123 and now it appears as pfB_abc123 on my dashboard. Thanks!

                              Hello ,

                              is there a possibility to add the negate rule on ports also ? I don't want to block some ports , aka in the top 20 country list . I modified the xml  and the inc file but it seems to ignore the option. Is there an other file that I must change that makes the option work ? Thx.

                                  I don't think there is an option to use "!" negate a Ports Alias in pfSense… You can edit an existing pfBNG Rule and see if you see it any different?

                                    Hi all,

                                    I find my dropbox syncing is blocked.

                                    In logs I see

                                    IBlock_BT_Hijack list contains 162.125.0.0/24 which is used dropbox.

                                    How should I proceed to get dropbox working again.

                                    Thanks.

                                      You need to create a Permit Outbound pass rule for the IP of you seedbox
                                      or get an IP outside that range from your provider.

                                        You need to create a Permit Outbound pass rule for the IP of you seedbox
                                        or get an IP outside that range from your provider.

                                        Just to be clear when I say dropbox I mean as in Dropbox the company
                                        Their client desktop app is trying to connect out to 162.125.17.0/24 and 162.125.32.0/24

                                        I've enabled suppression and manually added both above networks to pfBlockerNGSuppress Alias.  And then "reloaded"

                                        What I do not understand is your reference to a seedbox.  I am not sure if I have one of those or not … and yes I feel silly saying this.
                                        How/Where do I create this Permit outbound pass rule.  And how does pfBlockerNGSuppress tie in?

                                        I went ahead and creating a pass outbound in floating rules and moved it to the very top of the list.  I am not sure if this is what you meant or if it is correct.

                                          Seedbox … Dropbox, whatever rock you boat  :P

                                          Did you read the section in the picture.

                                          It tell you NOT to use pfBlockerNGSuppress Alias in FW rules  :o
                                          It tell you that suppression ONLY work for /32 or /24 networks.
                                          IBlock_BT_Hijack specify 162.125.0.0/16, so the "+" icon is not available in the Alerts Tab,
                                          Putting  162.125.17.0/24 and 162.125.32.0/24 in pfBlockerNGSuppress  is useless.

                                          So move the 2 networks to a new alias pfBlockerWhiteList
                                          Create a FW rule on LAN pass pfBlockerWhiteList
                                          or on the floating tab selecting all LANs interfaces
