TCP traffic forwarding

Hello
I am facing one situation. When I put the proxy settings in the browser, the browser only forward the http traffic with port 80 to the proxy. Well If I configure a transparent proxy I can forward all TCP connections to the proxy. But What If I want to forward http connections with ports other than 80 to my proxy server. I am feeling that this can be done using iptable rules at my gateway. Please help me.

Code:

iptables -t nat -A PREROUTING -i ethX -p tcp --dport YY -j REDIRECT --to-port YYYY

replace ethX with your lan interface. replace YY with the port you want redirected. replace YYYY with your squid port..
