Hey,

any input will be apprichiated,

here are the sites:
http://software77.net/cgi-bin/ip-country/geo-ip.pl
http://checkip.dyndns.org

and here is my conf file:

thank in advance.

look for the x-forwarded-for header in the squid conf. Squid, by default, includes this header. It will reveal the internal ip of the machine making the request.

tnk but I already found the answer, although you are right about the X-Forwarder, the feature that I was looking for was
header_access X-Forwarded-For deny all
so the page will see the request as comming from the squid itself.
