Transparent Proxy for more than port 80
-
Does anyone know how to make the transparent proxy handle more than just port 80.
The reason I ask is that I want to use it as a web filter with whitelist. I have enabled the proxy and loaded the whitelist and it works only on port 80. So say people want to bypass the proxy, all they need to do is find a cgi / web based proxy that has a https URL.
So how can I get the proxy to handle port 443 and the other common ports you would want to filter?
Thanks
