[squid-users] Re: Dns Error???

Dear

Completing my last email I isolated the problem like this:
if I configure the machine manually to use the proxy the problem does not
occur. This leads to a transparency problem. I think I used the necessary
compilation and squid config options to make it work smooth.
Obviously I am wrong. (But it does not justify why I am readind a DNS error from
squid error page!)

These are the options I used:

Compilation -
        --enable-linux-netfilter

Squid conf -
        httpd_accel_port 80
        httpd_accel_host virtual
        httpd_accel_single_host on
        httpd_accel_with_proxy on
        httpd_accel_uses_host_header on

Iptable Rule
        /usr/sbin/iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 \
        -j REDIRECT --to-port 3128

What else can bo done?
