      i assume that varnish listens on port 80 and the wan firewall rule would allow access?

      how would i confirm that its working through varnish?

        Well, widget should show it to you but you can try to stop varnish and see if you can access internal server or if publishing has stopped.

          per your suggestion i stopped varnish which made the website unreachable/not accessible

          is this the expected result?

          original problem of nonupdating widget remained when i restarted varnish (in case you were curious)

          all the best and thanks in advance

            Yes.

            I have no idea how to help you right now.

              as a last ditch i uninstalled and resinstalled varnish.

              this is the part where i hang my head in shame for not doing proper troubleshooting before posting.

              [shame]

              i had installed and was working from the varnish3 package.  that was the package that was not populating the widget.  i uninstalled varnish3, installed varnish and it works great, which the widget updating as it should.

              [/shame]

              so that was the issue.

              thank you marcelloc for all of your work

              best

                Thanks for the feedback. I'll check if varnish3 changed something that widget can't read.

                  Hiya,

                  I had install varnish on pfsense and everything was working fine.

                  I had to rebuild my firewall and now my websites are down.

                  I followed this:

                  First be sure your pfsense gui is not listening on port 80 (system-> advanced)

                  mine is on https and port 441

                  Varnish config begins with backend configuration

                  Each backend means a webserver

                  inside each configuration, you must provide:

                  Backend name = test
                      Ip Address = 192.168.2.10
                      Port= 80
                      Probe URL= http://www.mywebsiteaddress.com
                      Probe Interval (5)
                      Probe Timeout (1)
                      Probe window (5)
                      Probe Threshold (3)

                  on backend mapping, you could choose

                  map=host
                  match=equal
                  expression=www.mydomain.com (for first web server)

                  save backend config

                  on settings

                  Listen port=80
                      Managment interface=127.0.0.1:85
                      storage type=memory
                      cache storage size=1024

                  on General VCL settings, check all options  # checked all options

                  all other options on settings could be in default value

                  When I go to the website, I get a :

                  It works!
                  This is the default web page for this server.

                  The web server software is running but no content has been added, yet.

                  I think this is coming from pfsense and not getting redirected.

                  I have varnish 3 installed.

                  Hope someone could show me my mistake.

                  On the wan I have this rule:

                  TCP * * WAN address 80 (HTTP) * none

                  I have rebooted the firewall a few times

                  Cheers,

                  Raj

                      did and no joy

                      the only way I got one of the website to work was this :

                      host equal www.mywebsite.com

                      and

                      host equal mywebsite.com

                      previously i do not remember having it like that as I have screenshot of varnish setting from before.

                          the widget will show backend status and to see varnish logs, you can use varnishlog from console

                              Hi Marcello, I have the same problem with my pfsense:

                              2.0.2-RELEASE (amd64)
                              built on Fri Dec 7 22:39:43 EST 2012
                              FreeBSD 8.1-RELEASE-p13

                              and Varnish 3.0.2 pkg v.0.1

                              I tried all suggestion you gave but nothing solve my problem: when I call the Varnish on litening port (8082 in my case), only the firt defined backend is returned, no change if I call www.call1.com or www.call2.com (both domains point to public ip of pfsense of course).
                              this is the configuration:

                              backend crmBACKEND {

                              used in catch_all

                              .connect_timeout = 100s;
                              .probe = {
                              .request =

                              "Connection: Close";

                              requests from the client will also be piped through and

                              left untouched by varnish. We don't want that.

                              set req.http.connection = "close";

                              Note: no "pipe" action here - we'll fall back to the default

                              pipe method so that when any changes are made there, we

                              still inherit them.

                                  what backend status you get on dashboard varnish widget?

                                  both up with green arrow
                                  no other value is shown in the fields "cache hits" etc., just shows the two backends with status

                                  thanks
