Group ACL in Squidguard behaving strangely

[Vlee]

Hello all,

I have 2 PC ips set in a group ACL. They both have the target rule to block webmail.
One pc blocks webmail while the other does not.

• Both PC IPs are set in the same exact Group ACL.
• I already checked to make sure the PC that is not blocking was not in another ACL. All other ACLs I have also blocks webmail and works.
• I have tested the ACL by adding different IPs in and the webmail does get blocked for those IPs.

What could be the issue?
Please let me know if there is some other info that I should post that might help.

Thank you

• Victoria

Have you verified that the PC that doesn't block webmail is actually using the proxy?  Are you running transparent or explicit?

The PC is using the proxy. It blocks other sites for different rules like the games or movies rule.

I am running transparent mode.

What happens if you take the IP addresses of two systems (one being the non-blockable), and switch them?  Does the problem follow the IP address or the system?

Post your squidguard filter config (Services - Squidguard - Log - Filter config) and the IP address of the misbehaving system.

That's a good suggestion. I will test it out and let you know the results.

Below is my squidguard filter config.
The IP of the troubled system is 192.168.1.167

You appear to have 2 different WebMail entries, blk_BL_webmail and Webmail_Block.  Other than that, everything looks good to me.  What version of pfSense and squid/squidguard are you using?

Pfsense 2.3.2
Squid 0.4.21
Squidguard1.14_3
The blk_BL_webmail is  the original target rule.
Webmail_Block is a target category I created for a test and can be removed.

I took the two IPS (the non-blockable and blockable one) and switched them.
The results were strange.
The non-blockable computer was given the blockable IP but still behaved the same way. (It wouldn't block webmail)
The blockable computer given the non-blockable IP then behaved just like the non-blockable computer. (It also wouldn't block webmail)

When switched back behavior returned to the original state. (One blockable one non-blockable)

You have something very weird going on.  I couldn't even begin to guess at what it might be.  Please report back if you get to the bottom of it.

Yes, I agree it is very strange. Thank you for trying to help.
