      So far so good except the internet definitely seems slower and on a fast machine. One more clue to the puzzle; I happened to stop the squid service from the services page to see if squid was slowing things down and it made all websites start pointing to the pfsense login again. Very strange. I turned the service back on and everything was back to normal.

      Also, the lightsquid config page says "shedule" in a few places. How do we get that fixed?

          Hi dvserg, glad you're on this thread!

          It think Eric complains about spelling. It should be: schedule

            Ohm.. This is grammatic error. :(  I learned English poorly in school.:_(
            If you can - please check Lightsquid interface for grammatic and write me - i fix this.
            ps
            Sorry to me, all.

              Dvserg, do you have an idea why Eric's traffic is redirected to the pfSense webGUI when disabling the transparent proxy?

                It actually happens when I turn transparent proxy on. It also happened when I shut down the squid service though. Doesn't make sense to me.

                  On transparent mode squid make self redirect rules
                  May be have incorrect switching from transparent to non-transparent mode
                  Try switch to transparent and them to non-transparent once more.
                  If problem also exists - paste you /tmp/rules.debug in topic or in PM
                  –-
                  Also what installed packages you have?

                    I am seeing the same issues where the internet is far slower when the proxy is enabled.  Please see my post here…

                    Also, as suggested above, I have included my rules.debug - though I am not having issues with traffic being redirected to the GUI.

                        Eric & Heiko:

                        What type of hardware are you using when you can see the decrease in speed?
