Squid Transparent Proxy Issue
-
From Proxy server | General settings did you enable LAN as interface and 'Allow users on interface' is ticked?
And just to be sure 'Transparent proxy' is enabled as well?
Upstream Proxy is empty and what about 'Access control'? -
LAN is the interface and yes 'Allow users on interface' is ticked. I have no acl rules at all. Transparent proxy is definitely enabled. Everything else in the Squid config is default.
I recently restored pfsense to factory settings. Didn't help. So I reinstalled pfsense from the live cd and it worked great. So then I started restoring previous and it broke again. So again I've reformatted and installed pfsense along with squid. I am in the process of tweaking one thing at a time to figure out what is breaking it and causing this strange behavior.
-
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?

What this mean? Can you show screenshot?
Only create please new topic. Lightsquid different package, and I was able quickly to find a new theme.

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

It think Eric complains about spelling. It should be: scheduleOhm.. 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…
http://forum.pfsense.org/index.php/topic,7186.0.htmlAlso, as suggested above, I have included my rules.debug - though I am not having issues with traffic being redirected to the GUI.

Please see also this ticket http://cvstrac.pfsense.com/tktview?tn=1557, i can duplicate this behaviour.

Eric & Heiko:
What type of hardware are you using when you can see the decrease in speed?
