Hi !!!

I've installed a Squid box transparent mode (3STABLE7) with Debian. A
router send all the request to the port 80 to my squid box on 3128
port.

I've problems with google pages. Sometimes when somedy try to sail in
google the result is a http://www.google.com.ar/sorry/?.

"strip_query_terms off" in your Squid.conf will allow you to see the text after the question mark.

 This page say
something like the ip origin maybe is a malicious source, like a virus
or spyware.

I put in my squid.conf exepcions to google:

acl exepciones dstdomain "/usr/local/squid/etc/exepciones"
always_direct allow exepciones

*sigh* http://www.squid-cache.org/Versions/v3/3.0/cfgman/always_direct.html

And I quote...

   Here you can use ACL elements to specify requests which should
   ALWAYS be forwarded by Squid to the origin servers without using any
   peers.  For example, to always directly forward requests for local
   servers ignoring any parents or siblings you may have use something
   like...


The important bits are "by Squid" and "without using any peers". Once the traffic has been handed to Squid (be it via specifying the proxy explicitly in the browser, using WPAD or interception) Squid has to handle that traffic. If you want to bypass Squid for some Internet traffic don't send that traffic to Squid.

and the exepciones file is as follws:

.google.com
.google.com.ar
.gmail.com

but nothing changes.

Any idea?

Set your router up to pass traffic destined to Google directly to Google (and not to Squid). Otherwise track down and eliminate the traffic that is causing Google to view your clients with suspicion.

Is posible than a lot of requeriments with the same ip (the proxy ip)
causes this behavior?

Not unless its a very large amount of requests.
But a lesser amount of requests doing abusive behavior from one IP, or anonymous proxy might also cause this. I've usually found squid being blocked by google to be open-proxies with spammers playing around.

We'll be happy to check your config and point out security hole if you don't mind sharing it.
