Forwarding some sites through proxy?

Hi there,

I was wondering how I could setup my router to forward only certain (isp blocked) sites through a proxy server and leaving all other traffic as is?

Thanks!

You can run squid (squid-cache) as proxy-only on your openwrt, and configure it to proxy certain sites to a parent-proxy.
However, steep learning curve, in case you do not know squid.

If you want to micro-manage, this would be basically a task for policy based routing - but that get's out of hand quickly.
