hi, I am using SQUID 2.6.STABLE17 with CentOS 5, & BIND DNS SERVER configured on the same box, i have configured squid as transparent proxy with all default settings , and applied iptables rule by using the following command iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128 i am able to browse http websites, but when i try to open https sites, such as, gmail.com, hotmail.com etc.. i am not able to get any response from the proxy. i have also tryied with forwarding 443 (https) port to the 3128 (squid) port but still no success.
