Squid 3.3.4 package for pfsense with ssl filtering

exograpix

In spite of all my effort still certificate error as soon as I enable ssl filtering , help guys.

marcelloc

I have loaded ca certificate in trusted root certificate and webconfigurator certificate in personal (through certmgr.msc). but still shows certificate error in internet explorer. please suggest what to do.

the only place you need is trusted root certificate on ie and firefox.

Sure it works.

screenshot the certificate you get when firefox rejects.

It doesn't work any longer since I've updated to pfSense 2.1.1
It worked on 2.1

Thats my problem too , I have tried all combination but doesn't work, it used to work earlier quite smoothly, but somehow it stopped working now.

I request to sort this issue out asap to help the community and existing installs.

Need to see which system things changed with the upgrade.

Verify the "orphan" libraries for squid3-dev and what about OpenSSL?

OpenSSL does not like country codes longer than two letters, so remove entries that are not actually country codes

I have used the standard process as pfsense 2.1 (now even in previous version ssl certificate error is popping)

I installed pfsense.

Created the internal CA.

Created the server certificate (tried client too)

Import CA certificate through certmgr.msc in trusted root

Import other certificate in personal

copied missing files for squid.

Installed squid-dev from packages.

Configured squid as before with ssl filter and certificate and boom even microsoft default certificate error.

Checked, and the orphan libraries are on the system. Countrycode is 2 letters.
Squid http filtering works fine, only the https part results in certificate errors.

https is the problem and it is major concern now.

pfSense 2.1 (not upgraded to 2.1.1)
squid3-dev upgraded from 3.3.10 pkg 2.2.1 to 3.3.10 pkg 2.2.2

Bug for interception

Last lines of squid.conf generated by 2.2.1

# Custom options

always_direct allow all
ssl_bump server-first all
# Setup allowed acls
# Allow local network(s) on interface(s)
http_access allow localnet
# Default block all to be sure
http_access deny allsrc

Last lines of squid.conf generated by 2.2.2

# Custom options before auth

# Setup allowed acls
# Allow local network(s) on interface(s)
http_access allow localnet
# Default block all to be sure
http_access deny allsrc

Workaround until next version

Put at Custom ACLS (Before_Auth) box the lines

always_direct allow all
ssl_bump server-first all

Custom ACLS (After_Auth)

In addition to this, the box Custom ACLS (After_Auth) does nothing.

Rotate Cron duplicated

The upgrade also duplicates the rotate cron. You can see it if you have Cron package installed

0  	0  	*  	*  	*  	root  	/bin/rm /var/squid/cache/swap.state; /usr/pbi/squid-i386/sbin/squid -k rotate -f /usr/pbi/squid-i386/etc/squid/squid.conf  	
0  	0  	*  	*  	*  	root  	/usr/pbi/squid-i386/sbin/squid -k rotate -f /usr/pbi/squid-i386/etc/squid/squid.conf

Delete the old cron containing rm swap.state and look up the new option Proxy server: Cache management: Clear cache on log rotate

Thanks for all the support, worked like a charm, much relieved now, I am not blaming developer doing very good job, but this bug wasted almost two days of working time.

Again my appreciations , you are a life saver.

If you can, please explain cron thing in details.

bellera

Thanks for your good words!

I just created an account to say thank you. I've wasted all my afternoon after the upgrade, trying to guess why ssl bumping stopped to work at our school, but tomorrow everything (included the filter for the students) will be able to continue as expected.

bellera

Thanks for your good words!

Also, at school, www.bellera.cat :) :) :) :)

ssl_bump acls were inside auth loop. I'm fixing it right now.

This is still under devel. Current feedback says that's only working on i386 version.

where can i set below parameter permanently.

always_direct allow all
ssl_bump server-first all

Thanks in advance

With squid-devel pf 2.1 multi-WAN loadbalancing doesn't work. Failover works because default WAN gets switched.

More specifically, the floating rule-based setup that used to work for pfsense 2.0.x doesn't work any more. Squid only sends through default WAN, whatever that is at any point.

Marcello, can you please shed light on this? Whether this is squid-side issue or any nuance of 2.1.x?

Also, will it be possible to do loadbalancing with transparent SSL proxy?

Another question: does delay pooling-based traffic management work with transparent SSL proxy'ing?

Hi everyone. I hope you all are having a good night. I'm a newbie with pfsense. For the life of me, I can't even the the squid3 dev package to work at all. It won't work in transparent mode or anything, but the non dev squid3 works like a champ. Any thoughts on where to start to looking?
I'm currently running
pfsense 2.1.2
(works)squid3 3.1.20 pkg 2.0.6 works
(doesn't seem to work at all) 3.3.10 pkg 2.2.2

Thanks
