My aim is not Firewall functionality. My aim is to alleviate my slow link
to the internet by also caching .ra or .ram files which Realaudio uses...
and also use the proxy-network to find the absolute fastest way to the
source when connecting to a live server.

Is that possible somehow ?

Where do I find this information ?
