cd /usr/local/www/widgets/widgets/
fetch http://www.pfsense.com/packages/config/varnish64/varnish.widget.php

Just if you do not want to reinstall package.

The fix I've published was just to fix this file path.

oh…i still see the same widget

ok let me recap, i disable all my NAT, i set any port80 to any port 80 on my rules and i set my backend servers on varnish. i still do not get thru, not even getting the error503. Just showing me the connection has time out after a 1-2min loading

[marcelloc]

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

omg… u r right.... i couldnt start.... varnish.sh command not found

but i do see varnish.sh when i ls

[marcelloc]

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

Can you check your varnish settings tab?

my pfsense management port i change to https

change domain name on conf only for security purpose

[marcelloc]

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

varnish.sh
varnishd
varnishlog
varnishncsa
clamd

[marcelloc]

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.

18796  0  S+    0:00.00 grep varnish

looks like not running?

[marcelloc]

What about pkg_info cmd?

What does returns /usr/local/etc/rc.d/varnish.sh start

sorry what is the cmd to check the above ?

seems something not installed ?

saw this in my log… but i dont quite understand what went wrong

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

[marcelloc]

Remove quotes from your backend Test url

.url = ""/"";
