      @GoldServe:

      Has anyone noticed the dnsbl alert entries have the wrong time? Seems to be a few hours ahead from all the other firewall entries.

      Which DNSBL alerts? HTTP or HTTPS. For HTTP, it takes the request time from the remote Lan device. Could the clock be off on one of your desktops?

        Seems like HTTP timestamps are wrong. Which remote Lan device? All my laptops and desktops are Macs and their times are all correct. I am running pfsense in ESXI 6…

          I don't know if it matters but it seems like my /usr/local/etc/php.ini has this line set

          date.timezone="Etc/UTC"

          when clearly /etc/rc.php_ini_setup contains the following code:

          unset TIMEZONE
# Fetch the timezone from /var/db/zoneinfo if present
if [ -f /var/db/zoneinfo ]; then
	TIMEZONE=$(cat /var/db/zoneinfo)
fi

if [ -z "${TIMEZONE}" ]; then
	# Second option is from config.xml
	TIMEZONE=$(/usr/local/sbin/read_xml_tag.sh string system/timezone)
fi

if [ -z "${TIMEZONE}" ]; then
	# Last option, use default value from $g or Etc/UTC
	TIMEZONE=$(/usr/local/sbin/read_global_var default_timezone "Etc/UTC")
fi

          Anyone spot anything wrong? I verified the timezone is correct by running the script /usr/local/sbin/read_xml_tag.sh string system/timezone

            Hi,

            same situation in my environment. I changes from HTTPS WebUI to HTTP because WPAD is hosted on pfsense itself. But i defined all private IPs to go DIRECT and not using the proxy in the WPAD files. But unfortunately it does not work.

            Further I disabled auto proxy configuration and hardcoded the proxy in my browser but DNSBL still does only work with HTTP (pfsense WebUI page) but not with HTTPS. Further it does not log anything :-(

            PS:
            Anybody here who could suggest a good DNSBL which focuses on command and control server and such stuff?

            can u post ur wpad file content ,  ( Look my wpad file , for me after instructing wpad to give Direct connection to 10.x.x..x now its working okay

            @Nachtfalke:

            @killmasta93:

            FOR PEOPLE WITH GIF ISSUES READ THIS

            If your running WPAD and have on your navigator to auto detect proxy you WILL get the webGUI of pfSense instead of the GIF but disable the auto detect proxy on the navigator you then will see the GIF…It seems that WPAD overrides everything even when it comes to OpenVPN also...

            Thanks for that information. I am using WPAD with squid3 proxy. But I only get the WebUI with http websites. Is it working for you with httpS websites, too?
            Can you describe if you configued something sepcidal to get pfblocker-NG + squid (http + https) working?

            For me it looks like it is not working fpr https and it ios not working for http and https to see the bad websites in the "Alerts" tab of pfblopcker-ng.

            Regards

            @Nachtfalke:

            @killmasta93:

            Well I have pfBlockerNG working just for IP I had to disable DNSBL because WPAD was overriding everything. Because WPAD files are hosted on pfSense I had to revert to HTTP on the webGUI of pfSense. But by disabling auto detect proxy then works DNSBL but then WPAD wont work BUT transparent proxy will. I guess having WPAD and DNSBL wont work at the same time. UNLESS somehow on the wpad.dat a way to direct or ignore the 10.10.10.1 something that i wish it can do with OpenVPN. You get the HTTPS sites i guess because WPAD overlaps that but the http that would be the transparent proxy which DNSBL does not have an issue. Also depends if your webGUI is HTTPS or HTTP

            I also had issue with squid with wpad initially and  with BBcan177 help i resolved the issue with my setup

            i updated my wpad.pac file to make direct connected to 10.10.10.1

            
 function FindProxyForURL(url,host)
 {

    if (isInNet( host, "192.168.0.0", "255.255.255.0" )) 
        { return "DIRECT"; }
	 if (isInNet( host, "10.10.10.1", "255.255.255.0" )) 
        { return "DIRECT"; }	
	return "PROXY 192.168.0.1:3128";
 }

            now i am able to use proxy with wpad and also get 1x1 gif while blocking

              Hello! I just noticed today that pfBlocker is not "working" anymore. It's actually enabled and it was working fine blocking ads, now it seems nothing changed (I'm sure I haven't changed any settings) but I'm not getting ads blocked

              Here you can see it's enabled

              Any ideas on what's going on? There's no errors in the logs either :(

              It seems the latest blocked URLS were from April 19

                    Hello BBcan177,

                    I can ping the IP without problems, and all my devices are using my pfsense IP as DNS (as before) so it shouldn't be a problem there. However, if by "browse the DNSBL IP" you mean that I should get a reply when trying to open it from a browser then no, I get an error

                    But as I said, I get ping

                      Do you have a multi-segmented LAN? ie -vlans etc… If so, there is an option in the DNSBL Tab, to create a Floating Permit rule. Select all the Lan segments that need access to the VIP...

                      When you browse to the VIP, it should return the 1x1... Have you tried a different browser? or other LAN device?

                        Nop, I don't have VLANs.

                        Tried with Chrome but I'm getting same result

                        But I can still ping the IP. It seems a bit weird that I'm getting 265ms though, it's just a small LAN with a 8 port switch

                        Thanks again!

                            There is a new version of pfBlockerNG v2.0.11 for pfSense 2.3, which was merged today. Pull Request #114 here.

                            Changelog:

                            • Fix issues with de-installation (Not sure why anyone would de-install anyways :) )

                            • Fix an issue with 'States Removal', so that it only acts on 'Block|Reject' rules.

                                  Umm but I'm a bit lost about changing WPAD, I couldn't find anything related to pfsense and WPAD other than the guide I pasted above (https://doc.pfsense.org/index.php/WPAD_Autoconfigure_for_Squid) or is there an option in pfBlocker for WPAD?

                                    I can ping the IP without problems, and all my devices are using my pfsense IP as DNS (as before) so it shouldn't be a problem there. However, if by "browse the DNSBL IP" you mean that I should get a reply when trying to open it from a browser then no, I get an error

                                    Do you have a multi-segmented LAN? ie -vlans etc… If so, there is an option in the DNSBL Tab, to create a Floating Permit rule. Select all the Lan segments that need access to the VIP...

                                    When you browse to the VIP, it should return the 1x1... Have you tried a different browser? or other LAN device?

                                    Nop, I don't have VLANs.

                                    Tried with Chrome but I'm getting same result

                                    But I can still ping the IP. It seems a bit weird that I'm getting 265ms though, it's just a small LAN with a 8 port switch

                                    Thanks again!

                                    pic shows you opened as http

                                      There's one thing I don't get, though! This was working flawlessly, Squid + pfBlocker (even on 2.3) as I upgraded a week ago… why it stopped working now without touching anything? o.O

                                            It seems like this is one massive question board for the one plugin so I'm going to ask:

                                            I have 2.2.6-RELEASE (amd64)  > in the "alerts" area of pfblockerng I don't see anything logged in the dnsbl area
                                            I have 2.2.5-RELEASE (amd64)  > in the "alerts" area of pfblockerng I see everything including https notifications of limited info but ads are still blocked

                                            …so, is there a bug in the 2.2.6 release with respect to logging somehow?

                                            They're 2 separate FW's but I went through the settings and they match perfectly.  I also made sure the Windows server was in fact querying for DNS to the firewall and not anything else by blocking the server's IP > it then couldn't resolve external DNS hosts like google.com, yahoo.com but I could ping IP's (so not using DNS).  Once I unblocked it form the firewall, DNS worked again so I KNOW it's "working" like:

                                            hosts > query >> server >>> query firewall >>>> query public DNS + root servers

                                            • I also turned on unbound logging up to 5 or whatever the highest debug level and nothing jumped out at me...it's all "working" except for the alerts tab not showing what's blocked.  I also compared a known ad site (an online newspaper) from the 2 different sites and both pages are exactly the same in IE so I think what's happening is that it's dnsbl'ing the ads just not showing them in the alerts tab.

                                            Let me know if you find anything.

                                            Thanks!
