Squid 3.3.4 package for pfsense with ssl filtering

Legion

Interestingly it's timing out for me too Marcello. And it's worked for me before, many times. I'm at work, in Oz, corporate firewall but it's not blocking.

Sorry for my bad english.

Can someone explain, how to block https urls with squid3 + squidguard?

Http urls are blocked correctly, but https urls won't be blocked :(

Thank you so much.

Create a Certificate authority on pfsense
Export ca certificate on gui and import on each client you what to filter ssl without certificate error messages
Enable ssl interception/transparent proxy on squid3-dev gui.

Marcelloc I am telling you it is DEAD. We have tried going outside pFsense, direct to our ISP, and also on our VPN.

It is unreachable.

The PBI manager within pFsense works fine.

Why not update the Squid 3.3.8.package so we can access it from within pFsense rather than from a third-party website?

As I told you on other post.

Install squid3-dev
Enable ipv6 on system advanced
fetch missing libs from any freebsd 8.3

I've asked core team to include these libs on official repo, this way, postfix, freeradius2, squid3 and other package I do not remember now can be installed automatically via gui. But I had no success on it.

The libs are there to help people not to mess things up.

Last point. It's a dev package, not a release or stable one. So people who tries it must know how to workaround things.

Hi,

I am planning tu use squid3 for transparent proxy for http and ssl intercepting proxy (443) on a Multi-WAN environment.
So my question ist not directly related to the package but how do you use loadbalancing for ports 80/443 if these connections alsways have the same source like 127.0.0.1 ?

To make it a little bit clearer
I am not asking how to configure a pfsense with Multi-WAN and squid to use all WAN connections and not only one.
I am interested in how to make it work that port 80 and port 443 can be loadbalanced even if the source is always squid/pfsense itself (127.0.0.1) and so I can not balance based on the source-IP. Policy based routing for these two ports will not make sense and sticky connections - I think they will always use one WAN for these two ports.

I explained a little bit more here:
http://forum.pfsense.org/index.php/topic,68120.0.html

I would really appreciate any help so that I can configure my test machine and do some tests ;-)

Maybe with a lot of acls based on source ip acls to define tcp_outgoing address.

I'm seeing some posts related to problems with 127.0.0.1 load balance on 2.1

Interesting point. tcp_outgoing_address and ACL with source IP and source port 443 could do the trick. 3 tcp_outgoing each for every of the 3 WAN connection. Port 80 can be probably done with the gateway groups of pfsense in Manual Outbound NAT. Will give that a try.

Hi marcelloc. Does this version capable of blocking https sites in transparent mode?

Yes.

Thanks natchflake. I'm trying to download squid-3.3.5 from the above address given by marcelloc using also the procedure as instructed, but i'wasn't able to download it. It says Unable to fetch the file. Can I download it manually and save it in any pfsense folder using file manager packages? IF yes how can i install it once i've save it? for example i saved it to /usr/local..

Thanks

Hi,

please try to install squid3-dev form pfsense package manager. This will give you all you need. After that you have to fetch some single files from command shell. This should be enough.

This post should explain it:
http://forum.pfsense.org/index.php/topic,62256.msg371582.html#msg371582

At the moment I do not find the post where marcelloc posted all the missing libs/files you need to fetch manually.

Did you see the post marcelloc posted on top of your post?

ipis

Hi, while i continue reading

I'v found this instructed by marcelloc to other member.

. cd /usr/local/lib
. fetch url_for_libs

Download all libs from my ldd folder.

What doe's he mean by the "fetch url_for_libs" ?

Because what I tried is this on console "fetch //http://e-sac.siteseguro.ws/pfsense/8/All/ldd/"

and it says not found. Did I do it correctly?

ipis

Sorry I didn't see it earlier.

Thanks Nachtfalke and marcelloc :)

No need to fetch 3.3.5. Use default 3.3.8 from oficial repository.

ipis

Guys what i did was this to be exact

(8) shell
cd /usr/local/lib
fetch -o /usr/local/lib/libasn1.so.10 http://e-sac.siteseguro.ws/pfsense/8/All/ldd/libasn1.so.10

But it says not found.

I feel ashamed cause i wasn't able to install them while others can :(

ipis

Is there a way to copy the missing libs directly to the pfsense without fetching?
