      When I got it working with squidguard, I will attend to that problem.

        I am a bit stumped on why Squidguard is not working for you (as I am new to this) list your squid, Squidguard and System: Advanced: Firewall and NAT settings.

          Transparent Proxy.

          Integrations Settings:
          cache_peer 127.0.0.1 parent 3125 0 name=havp no-query no-digest no-netdb-exchange default;url_rewrite_program /usr/pbi/squidguard-squid3-amd64/bin/squidGuard -c /usr/pbi/squidguard-squid3-amd64/etc/squidGuard/squidGuard.conf;url_rewrite_bypass off;url_rewrite_children 16 startup=8 idle=4 concurrency=0

          Custom Acls:
          always_direct allow all
          ssl_bump server-first all

          Only one nat rue for redirecting https traffic to squid.

            do you put amd64 instead of i386 by mistake or are you running amd64?

                is the squidGuard service able to run? or is it erroring? Also try using proxy port 3128 in Proxy port under Squid General Settings.

                Also here is my Custom ACLS (Before_Auth) in squid (Trying to get windows updates working)

                acl WindowsUpdate dstdomain windowsupdate.microsoft.com
                acl WindowsUpdate dstdomain update.microsoft.com
                acl WindowsUpdate dstdomain activex.microsoft.com
                acl WindowsUpdate dstdomain download.windowsupdate.com
                acl WindowsUpdate dstdomain codecs.microsoft.com
                acl WindowsUpdate dstdomain stats.updates.microsoft.com
                acl WindowsUpdate dstdomain c.microsoft.com
                no_cache deny WindowsUpdate
                http_access allow WindowsUpdate
                always_direct allow all
                ssl_bump server-first all

                This does not work

                  Hi, squidguard is running and no error in the log files.
                  Port squid is 3128.

                    But it is not filtering anything? Check Target Rules in squidGuard.
                    In SquidGuard: General settings
                    tic Check this option to enable blacklist
                    Blacklist proxy is your pfsense router ip

                    then clear your cache or try private search and try now

                      If I deactivate ssl bumping it works just fine.

                            Yes, squid3-dev. The squid.conf is under Diagnostic / edit File/  browse to /usr/pbi/squid-amd64 or squid-i386 /etc / squid / squid.conf

                                  I still have not found a fix for windows updates (thinking there is a bug in squid3-dev)

                                  Where can we post bugs for squid3-dev? Here?

                                  So far I have found issue with
                                  Windows updates
                                  Adobe updates

                                  SSL filtering websites issues
                                  https://dolphin-emu.org/
                                  will add more later

                                    Hi,

                                    is your squidguard running as parent from squid?
                                    If the answer is yes and you are using ssl bumping, then it is getting bypassed.

                                        Yes, custom acl which is not getting decrypted.

                                          Yes, custom acl

                                          I tried custom ACLs but they did not work.

                                          which is not getting decrypted.

                                          Is that the reason why the custom ACLs are not working?

                                          I guess the question is:

                                          Has anyone been able to get windows updates working using custom acls for SSL filtering?

                                          And if so can they post an example (as I am sure other people are having the same issue with this)
