[squid-users] Fwd: transparent filtering

I am an idiot. I didnt read the howto properly. I now realize that this
http://en.tldp.org/HOWTO/TransparentProxy-5.html page discusses how to do redirect with
squid on the same server as the firewall. The url that I have in the previous email is
if squid is on another box. I have set the following iptable command but without success

iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128

From the client I am getting error URL could not be found and am getting the following
in the access.log

1081968754.867 22 10.1.2.100 TCP_DENIED/400 1435 GET / - NONE/- text/html
1081968755.020 1 10.1.2.100 TCP_DENIED/400 1457 GET /favicon.ico - NONE/- text/html
1081968816.434 4 10.1.2.100 TCP_DENIED/400 1481 GET /products/firefox/start/ -
NONE/- text/html
1081968816.601 0 10.1.2.100 TCP_DENIED/400 1457 GET /favicon.ico - NONE/- text/html


Any advice?

Thanks,
Dhaval
