      maybe there is something missing on your varnish setup.

      try to run it from console to see if there are any erros

      /usr/local/etc/rc.d/varnish.sh start

          /usr/local/etc/rc.d/varnish.sh is generated when you enable varnish and save config.

          Can you check your varnish settings tab?

                The conf looks fine. Are you still unable to start varnish?
                What files do you have on /usr/local/etc/rc.d ?

                    The file is there and package is installed, it should work.  ???

                    Just to check, see if varnish package is installed with pkg_info on console.

                    ps ax | grep varnish will show if there is any varnish process running.

                                  and i kvm into my pfsense and saw this on the screen.... seems like its stucked at the loading of varnish....

                                  i think i messed up the pfsense somewhere

                                    Remove quotes from your backend Test url

                                        @marcelloc:

                                        Each backend means a webserver

                                        inside each configuration, you must provide:

                                        • Backend name = WindowsServer

                                        • Ip Address = 192.168.1.4

                                        • Port = 80 <– Q

                                        • Probe URL = "/"(if your server has a valid page on "/")

                                        • Probe Interval = 5

                                        • Probe Timeout = 1

                                        • Probe window = 5

                                        • Probe Threshold = 3

                                        Q:
                                        Can I enter multiple listening ports e.g. port: "80, 443"? Or should I configure that host several times according to how many ports it is listening on?

                                        Thanks,

                                          I think you need one port for each config as varnish is going to check backend health as well send traffic based on this port.

                                          Keep in mind That varnish implemets http balance/cache only. If you what to balance https as well, haproxy can do this.

                                          Pound and relayd can do client/firewall ssl comunication and then forward client request to varnish, but there is no gui options for this yet.

                                            Hate to jump on someone else's thread, but I've gone threw all the same motions, but still no results.

                                            web1.domain.com
                                            web2.domain.com

                                            All end up pointing to the pfSense login, so my question is simply this… What IP do you point the Rule to? the pfSense box that host Varnish?
