Any chance of getting a working transparent proxy again?

notaduck

Can i ask you how i can see if i am using the cache or not?

i have transparrent mode running with an growing cache? so it seems to work just fine here

this is my syslog, as a proof ;)

I have the same issue. Not working on transparent mode at all….only forwards HTTPS sites.

So I had to uninstall and let it be...

I think it´s just because https uses port 443, not 80, as squid does.

Do u see any traffic in the WUI under "real time" in the squid section?

notaduck

yes i do ;)

You have to enable loggig under logging settings.

I also had logging enabled.

Strange to me how you have gotten transparent mode running without mods.

This is theexact way i did my squid configuration http://techknight.eu/2015/03/13/pfsense-setup-and-configure-squid3-transparent-proxy/

i just had to disable icap and enable loggin :)

I hope it helps

When using Squid3 then ClamAV is good to have.

Can anyone post a working c-icap.conf file??

notaduck

i don't think so :S
i have seen so many topics without a solution :S

Thanks, but I already knew about that article.

Still no working transparent mode here :'(

hmmmm…. I just don't understand why it shouldn't work for you.

working for non https transparent mode

do a fresh install of 2.2.1 @ x64

install squid3 and squidguard dev

create the necessary wdap files as per https://doc.pfsense.org/index.php/WPAD_Autoconfigure_for_Squid

use urlresolver instead of dhcp forwarder in 2.2.1! - same idea and setup

using the file manager and editor

create a /cache directiory and set it to 30gb or so in squid 3

configure squidguard

start squid 3 and put on transparent mode

do not sue the antivirus atm as it gives icamp errors

you may want to use the service watch to retreat squid3 if it stops,etc

I played around quite a bit and held off upgrading from 2.1.5 until just this week. I've tried many times and always had to roll back to 2.1.5
vmware workstation environment, 64bit pfsense.
Uninstalled squid/squidguard. Then ran the update.
install squid 3
install squidguard development (could never get the main version running).
download blacklist.
enable clamav in squid. Then disable it.
re-download blacklist.

Seems to work now. The main issue now is that after a reboot, everything crashes and fails to restart.
Fix is to enable then disable clamav in squid. Then re-download blacklist and it stays up and running.

Definitely not good, but at least it's working. Nowhere near as stable as when we were on 2.1.5 (or any previous version for that matter back to 1.2)

Not pushing my luck on https proxy until this part is better.

With squidguard dev installed and starting, squid now always crashes:

Apr 7 07:53:07	squid[60452]: Squid Parent: (squid-1) process 69996 will not be restarted due to repeated, frequent failures
Apr 7 07:53:07	squid[60452]: Squid Parent: (squid-1) process 69996 exited with status 1
Apr 7 07:53:07	(squid-1): The redirector helpers are crashing too rapidly, need help!
Apr 7 07:53:06	squid[60452]: Squid Parent: (squid-1) process 69996 started

The howto you mentioned says: "To use squid authentication, squid cannot be used in transparent mode. "

The rest you suggested does not seem to be related to the transparent proxy-problem, I guess, but thanks though.

Did I get you right that squid transparent mode only seems to be running on pfsense 2.15?

So what did you mean with "ran the upgrade"? You upgraded to the recent 2.2 after all, anyway?
