          I also had logging enabled.

          Strange to me how you have gotten transparent mode running without mods.

            This is theexact way i did my squid configuration http://techknight.eu/2015/03/13/pfsense-setup-and-configure-squid3-transparent-proxy/

            i just had to disable icap and enable loggin :)

            I hope it helps

              When using Squid3 then ClamAV is good to have.

              Can anyone post a working c-icap.conf file??

                  Thanks, but I already knew about that article.

                  Still no working transparent mode here  :'(

                    hmmmm…. I just don't understand why it shouldn't work for you.
                    can you try to post your squid slog?

                    btw. it annoys me that it isn't working because i am the one who wrote the article -_- and it works just fine for me

                          working for non https transparent mode

                          do a fresh install of 2.2.1 @ x64

                          install squid3 and squidguard dev

                          create the necessary wdap files as per https://doc.pfsense.org/index.php/WPAD_Autoconfigure_for_Squid

                          use urlresolver instead of dhcp forwarder in 2.2.1! - same idea and setup

                          using the file manager and editor

                          create a /cache directiory and set it to 30gb or so in squid 3

                          configure squidguard

                          start squid 3 and put on transparent mode

                          do not sue the antivirus atm as it gives icamp errors

                          you may want to use the service watch to retreat squid3 if it stops,etc

                            I played around quite a bit and held off upgrading from 2.1.5 until just this week.  I've tried many times and always had to roll back to 2.1.5
                            vmware workstation environment, 64bit pfsense.
                            Uninstalled squid/squidguard.  Then ran the update.
                            install squid 3
                            install squidguard development (could never get the main version running).
                            download blacklist.
                            enable clamav in squid.  Then disable it.
                            re-download blacklist.

                            Seems to work now.  The main issue now is that after a reboot, everything crashes and fails to restart.
                            Fix is to enable then disable clamav in squid.  Then re-download blacklist and it stays up and running.

                            Definitely not good, but at least it's working.  Nowhere near as stable as when we were on 2.1.5 (or any previous version for that matter back to 1.2)

                            Not pushing my luck on https proxy until this part is better.

                              With squidguard dev installed and starting, squid now always crashes:

                              The howto you mentioned says: "To use squid authentication, squid cannot be used in transparent mode. "

                              The rest you suggested does not seem to be related to the transparent proxy-problem, I guess, but thanks though.

                                Did I get you right that squid transparent mode only seems to be running on pfsense 2.15?

                                So what did you mean with "ran the upgrade"? You upgraded to the recent 2.2 after all, anyway?

                                      Seems to depend on who you ask.

                                        Having another go at this, taking things slowly and making sure I've not overlooked anything.

                                        I'm seeing the following in cache.log on startup.

                                        Is this normal. Do I need to disable IPv6?

                                          I did this… not getting through to HTTP sites but only HTTPS as expected.

                                          Unchecked Suppress Squid Version -> clicked save.

                                          Rebooted.

                                          Now it worked with HTTP sites like it should.

                                          Squid version is 2.7.9 pkg v.4.3.6

                                          EDIT: pretty scary shit. It works for a short time, then it stops working again.

                                          And nothing in the logs at all!

                                            Squid2 was crap from what I understand.  Have you tried Squid3?
