[squid-users] URL access problem

Hi Fellows,

I am having some problems with my Web access using Squid.
All machines on my LAN can access normally de websites trough
the squid, but the some URL's cannot be had accessed by no
machine of my LAN without no apparent reason. It appears the
message of "URL not found". Outside of my LAN the URL is had
access normally.

The URL that I am having problems is : http://netserver.hp.com
in link "Technical Support" exists a redir for the link :
http://h20000.www2.hp.com/bizsupport/TechSupport/Product.jsp?prodTypeId=15351&locale=en_US&taskId=135

In my /var/log/access.log appears only the msg's of access for
the "netserver.hp.com" URL, and nothing about "h20000.www2.hp.com"
when I try to access the described link appear the message that I said.

here is a part from my /var/log/access.log:

### END OF ACCESS.LOG ####

I have a LAN accessing the Internet (WEB) trough a gateway
using (Squid + Iptables):
SQUID - 2.4.7
kernel - 2.4.18
glib - 1.2.10
glibc - 2.2.4
My gateway has 2 (two) NIC's - eth0 ( Public IP ) 200.xxx.xxx.xxx
                                 eth1 ( Private IP ) 192.xxx.xxx.xxx CLASS C
The Iptables Rule is :
####
iptables -t nat -A PREROUTING -s 192.168.0.0/16 -d 0/0 -p tcp --dport 80 \
-j REDIRECT --to-port 3128

iptables -t nat -A PREROUTING -s 192.168.0.0/16 -d 0/0 -p tcp --dport 80 \
-j REDIRECT --to-port 3128
###

My SQUID has a classic configuration with ACL's allow and deny :

http_access allow
http_access deny

including a "badword" file with a list of forbiden words.

what it can be wrong ?

grateful for the attention
