Squidguard Web Filter Issues

Nachtfalke

okay.

I think there is a mistake in the "Expressions" block.
Expressions are - that's the way I understand it - if an URL contains a word of this. For example if the expression is:

.porn.

This means every URL with the word "porn" in front, at the end or somewhere in the middle is blocked:
www.XYZporn.com
www.pornXYZ.com
www.ABCpornXYZ.com

You have to put your IPs and URLs in the block "Domain list".
The text above explains it. Just enter there:


google.com 12.23.34.45 12.12.34.34 34.34.34.34 example.com amazon.com

PS: If you are using IPs, you must be sure, that you didn't check the box "Do not allow IP addresses in URLs".
It is better to use domain names in the "domain list" so the IP behind this domain can change and you do not need to change this from time to time in SquidGuard. If it is not possible to use domain names, then remember the checkbox with "Do not allow IP addresses in URLs"

To your question if this make sense:
Yes it does. I am doing this the same way.

Sorry for the delayed reply.. haven't been into work for a few days, have been terribly sick with mono.

Anyway, I tried your suggestion of instead of having expressions, having all the domains I want to whitelist instead. Now instead of them all getting blocked on all workstations, it isn't blocking anything at all!

Should I post screen shots again? I really don't understand what I'm missing at this point.

Nachtfalke

Sure, you can post again all tabs of SquidGuard.

But you want to realize the same as I am doing and I posted all necessary options in my screenshots. Perhaps you are missing one little checkbox ;-)

Further, after changing anything in SquidGuard, are you applying "Save" and after this "Apply" on the first tab of SquidGuard ? This is neccessary for a working proxy filter!

Okay. Here are the updated screenshots. I hope you can help.

Filter is working perfectly on limited workstations but it isn't allowing all access to admin workstations.

Hi,

proxy3.png:

uncheck "Do not allow IP addresses bypass"
defaulf access: allow and NOT deny.
This page is for the admin workstations, like you call it ;)
All that you deny on this page is a restriction for you admin workstation.

proxy4.png:
Is ok, but here you can check:
"Do not allow IP addresses bypass" BUT ONLY if you dot not have any IP addresses in proxy5.png

Head up - you got it :-)

coachs88

Dang..

I have done all of these things and it still isn't working how I want. It is still blocking all access to limited workstations. Every other computer (admin) it is blocking access except the whitelist.

I don't understand what could possibly be going wrong at this point. :-[

Nachtfalke

Can you show me again your changed "Common ACL" tab.
And, do you click ALWAYS "Save" and "apply" on "General settings" tab ?

coachs88

Here you go.

Hmmmm, I can not see any difference to my filter config. Not sure why it is not working.

Please try to save and apply settings in squid guard again and then check "Filter GUI" in squid guard. Perhaps there is some info because it isn't working. please also try to check system logs after reconfiguring squidguard.

perhaps you can focus the maintainer of SquidGuard "dvserge" to this thread. I am at the end of my know how.
