Varnish help on setting up for multiple internal webservers
-
i apologize - i think im getting mixed up ! :)
per this thread, i removed the nat rule (which i previously had configured prior to installing varnish) for port 80
in order to have port 80 open (in order for traffic to reach varnish), i added a firewall rule on the wan for port 80 to be open
isnt this the correct config? :)
all the best and thanks for all
-
Yes, the setup is this way.
Are you sure it's working through varnish?
-
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

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=1024on 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
-
try to replace http://www.mywebsiteaddress.com probe url to a full url like http://www.mywebsiteaddress.com/index.html
-
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.
-
is there any logs to see why even though varnish is working pfsense is not redirecting properly pls?
Cheers,
Raj
-
the widget will show backend status and to see varnish logs, you can use varnishlog from console
-
Thanks @marcelloc for this topic
after a week to re read also re read to other post …
it's configure with success to serve multiple server behind 1 ip publicgreat package

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-p13and 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
.host = "10.8.0.1";
.port = "51231";
.first_byte_timeout = 100s;
.connect_timeout = 100s;
.probe = {
.request =
"GET /diagnostico.asp HTTP/1.1"
"Accept: text/*"
"User-Agent: Varnish"
"Host: www.site1.com"
"Connection: Close";
.interval = 10s;
.timeout = 100s;
.window = 1;
.threshold = 1;
}
}backend wwwBACKEND {
used in catch_all
.host = "192.168.1.2";
.port = "80";
.first_byte_timeout = 100s;
.connect_timeout = 100s;

.url = "www.site2.com";

}what is wrong? thanks in advance

what is wrong? thanks in advance
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 statusthanks
