PfSense 2.2: Squid 3.4.10_2 pkg 0.2.6 redirection not working in transparent mode

Steve Evans

I have the Disable webConfigurator redirect rule checkbox ticked as I have WPAD running on port 80 using the vHosts web server. Unfortunately iPhones etc don't use WPAD so I need transparency mode, but I've left it turned on for now.

I'm using the recent full 2.2 release.

I've just tried putting a pass all rule at the start of my LAN rules to see if that would fix any firewall issue, but it did no good.

2.2 amd64?

I've just rebooted the firewall with all pf rules reverted to those in /conf.default/config.xml. This should eliminate any firewall rule peculiarities. I'll let you know how that works once it's up.

Thanks,

I have two users on portuguese forum with same version 2.2-RELEASE-i386 and same issue.

Maybe it's related to squid pbi package compilation under i386 system.

Steve Evans

Interesting.

Given that I see the lack of redirection with nc as well as squid I'm inclined to think this may not be an issue with squid at all, but rather with pf. That'd be quite a fundamental problem for pfSense!

I made THIS post in the Firewalling forum to see if that provides any insight. For now I'm going to see if a minimal pf configuration helps.

Thanks,

Steve

With the default firewall rules, squid is still not working in transparent mode.

As you're seeing multiple reports of this, could you please raise a bug report that captures the collective experience.

I'll need to create an i386 virtual machine to get same problem. On all my labs, transparent proxy is working fine.

Steve Evans

OK, thanks.

I thought the following might be of use to confirm the squid configuration I have installed.

Now here's an oddity. There are two squid binaries installed. Potential for inconsistencies here…

@Steve:

Now here's an oddity.

This is one of pbi behaviors. same binary, different folder, different results. (Imagine get all it working together :))

And here is the confirmation that pbi build on i386 is outdated

'--disable-ipf-transparent' '--disable-ipfw-transparent'

Go to amd64 and it will work :)

Thanks for your feedback

Steve Evans

Hi Marcelloc,

As I'm running on a Pentium-M on a Watchguard Firebox x750e I'm afraid that I'm constrained somewhat to only running 32 bit. That said, one of the great things about pfSense is it's a great application to run on older hardware, so thanks for keeping the i386 version alive!

How soon might a package update for i386 be forthcoming would you guess?

Thanks again,

Steve

Just wait core team to compile it again. The compile args were fixed few weeks ago but only amd64 was rebuild.

I am running 2.2-RELEASE (amd64) and transparent mode isn't working either.

Not sure what's wrong, I am getting the following errors on the system/squid logs.

Problably you've enabled transparent mode but did not selected any interface for interception.

Could you please confirm that my experiment using nc works in your setup. This will help determine if the issue is with squid or the firewall.

Hi Marcelloc,

Any idea when the new package might be available?

Thanks,

No. I'll ping Renato again and ask for a update to 3.4.11

Steve Evans

Thank you.
