      I have same problem
      "squid -v" give configure options. In they are present:
      '–disable-ipf-transparent' '--disable-ipfw-transparent' '--disable-pf-transparent'
      Can this explain problem?

        If these options are set, surely it will affect transparent proxy. Going to read up on those options, if this proves to be true the only thing we can do is roll back to a
        previous version, or the devs may need to update the Squid package.

        Cheers.

          Definitely a problem with the package. Read here for intercept not working on 3.4.x:

          https://forums.freebsd.org/threads/transparent-proxy-with-squid33-and-pf.48038/

          As this affect transparent proxy on PfSense, the next thing to do is submitting a bugreport.
          If above is not correct, please feel free to comment, else I'm off to fill in the bugreport.

          Cheers.

            I am experiencing the same problem with transparent squid3 on the latest 2.2-RC.  I ran the squid -v and saw the same compile flags mentioning disabling transparent proxy.  I have just finished a re-install with the latest RC to see if my efforts to troubleshoot screwed up squid3, but no luck.

            Escorpiom, if you are filing a bug for this, can you also add the changes necessary to get squid3 to run in non-transparency mode?  The user HMH had posted the necessary symlinks to resolve some missing libraries:

            ln -s /lib/libmd.so.6 /usr/lib/libmd5.so.0
ln -s /usr/pbi/squid-amd64/local/etc/squid /usr/local/etc/squid
ln -s /usr/pbi/squid-amd64/local/libexec/squid /usr/local/libexec/squid

            adjusting amd64 for i386 as necessary.  I had to set these links in versions prior to the RC and also with the latest RC this afternoon.

              Just got to the bottom of this.
              This Squid package for 2.2RC is not build correctly and actually it's quite sloppy.

              Three errors:

              • Package need to be compiled with "–enable-pf-transparent" as pointed out by firstzerg
              • Use the "tproxy" directive to be a completely transparent proxy
              • Instead of port 3128, use port 3129 for intercepted traffic.

              Details can be found here:

              http://wiki.squid-cache.org/ConfigExamples/Intercept/OpenBsdPf

              If Squid 3.4.9 is a beta package you may as well remove it from the list, because it definitely doesn't work.

              Cheers.

                  Sorry but so far I did the troubleshooting and it's a confirmed problem with the package.
                  I'm fairly new here and maybe I misunderstand the priorities of the devs, or maybe Squid is not an essential PFSense component.

                  Anyway I do not feel we have to fiddle around with packages that are broken or have install issues, simple request: If it isn't finished just don't release it.
                  Don't let people sort things out on their own without even commenting on issues.

                  Bug report created:

                    squid3-dev 3.3.13_2 is now working in transparent mode.

                    I installed 12/20 RC build and then performed a clean install of squid3-dev.  When I first enabled transparent mode, it failed.  I left it configured for transparent mode and simply rebooted the firewall.  When it came up, it all works (verified by real time tab).

                    I will see if the simple reboot works for the squid3 3.4.9_1 package later when I can reboot router without impacting users.

                      Yes, 3.3.13 works.
                      Sadly I'm in the same boat, it's not possible to experiment without causing trouble for my users.
                      I'll test stuff after midnight.

                      A few days ago there was a second package released for Squid 3.4.9, but that one still won't work for transparent proxy.
                      Also tried creating a rule to intercept port 80 traffic and redirect to port 3128 or port 3129, but Squid didn't pick it up.
                      This makes me believe that there may be other issues besides transparent proxy not working.

                      Cheers.

                        I have found every time I do a firmware update in 2.2 rc build's, I have to re-install the squid  2.7.9 pkg v.4.3.6 package every time and all is well. Settings are still the same just refresh the package install. If am unable to surf the web! I have no special settings pretty much basic and in transparent mode!

                          I've just made some more tests with Squid 3.4.9.
                          As transparent proxy doesn't work, it would be possible to create NAT rules to redirect traffic to Squid.
                          Setting the browser config to use the proxy on port 3128 works, so redirect port 80 to port 3128 should work just fine…

                          Not so. I found that Squid somehow strips the "http" part, resulting in an "invalid url".
                          This is the output from the access log:

                          192.168.31.27 TAG_NONE/400 3555 GET /?host=m.telegraaf.nl&hdn=%2FhmMlNFJ%2FfNLigi3ZtUwuQ%3D%3D - HIER_NONE/- text/html
1419307530.384      0 192.168.31.27 TAG_NONE/400 3551 GET /article/23484473/skiester-14-zwaargewond-door-botsing-tirol - HIER_NONE/- text/html

                          the NAT redirect rule however works fine. It's Squid that somehow doesn't know how to process redirected traffic.
                          So in short, I still haven't got a clue.

                          Cheers.

                            Today the Squid package was updated to 3.4.10.
                            Issues still remain, it is not possible to redirect traffic by means of a NAT rule, error persist:

                            "invalid URL".

                            Cheers.

                            Edit:
                            Activating the transparent proxy option now yields a different error instead of "no traffic received", observe the pic:

                              Todays update did not resolve the issues with transparent proxy.
                              Manual redirecting traffic to port 3128 still doesn't work, above described issue persists.

                              Cheers.

                                squid3 beta 3.4.10_2 pkg 0.2.1 has –enable-pf-transparent compilation flag…
                                but now there is another problems:

                                no libecap.so.2 in path variable
                                this help my:

                                ln -s /lib/libmd.so.6 /usr/lib/libmd5.so.0
ln -s /usr/pbi/squid-amd64/local/lib/libecap.so.2 /usr/lib/libecap.so.2
ln -s /usr/pbi/squid-amd64/local/etc/squid /usr/local/etc/squid

                                with transparent requests in access.log looks like this:

                                1420270719.456      0 127.0.0.1 TCP_DENIED/403 4169 GET http://google.com/ - HIER_NONE/- text/html

                                I have no idea why squid blocks localhost and why there are two requests
                                Оther sources suggest to redirect through ipfw… but pfsens is not working with ipfw

                                P.S. Sorry for my english  :)

                                  The squid 3 package is currently only a disaster with 2.2 :/

                                  • Transparent Mode does not work

                                  • .pbirun hangs after installed squid3 package and causes high cpu load
                                  • the tcp port 3128 is set to closed, instead to listen  (tested with netstat)

                                    Thanks both for sharing your findings.
                                    Port 3128 is not closed I believe.
                                    I found that adding this directive in squid.conf:

                                    http_port 3128 accel vhost allow-direct

                                    and restarting squid from the console (not GUI)
                                    makes the proxy work in "transparent" mode.
                                    I put it in quotes because normally the directive "intercept" should work for Squid 3.
                                    So for me it's unclear if "accel vhost allow-direct" does something else.

                                    Cheers.

                                        Yes, it should be. Please everyone try the latest and report back. 2 of the 5 remaining open 2.2 bugs are for Squid.

                                            Feedback is in the bugreport, seems transparent proxy is still not working for some.
                                            Perhaps it's because of PfSense RC build, I'm still on a December build.
