ffproxy question

[Bart Silverstrim]

I'm trying to configure ffproxy on Ubuntu to act as a transparent proxy, 
but it would appear that the package for ffproxy for Ubuntu has been 
customized to some degree.

Are there any users of Ubuntu out there running ffproxy who could share 
some hints and tips on configuring it?  I'm trying to have it log all 
the websites users visit, as well as selectively block lists of URLs, 
plus some sites that are hit via HTTPS.  It would also be nice if it 
logged IP addresses of machines that visit sites in the logs.

Also, is there an easy way to have all IP traffic incoming on port 80 
redirected to port 8080, or do I need to try moving ffproxy to listen to 
port 80 (and 443)?  I can tell a DHCP server to use the machine as a 
gateway, so that part isn't the difficult part, it's getting the 
requests visible to ffproxy...well, that, and configuring it to work 
properly.

Any help or pointers would be appreciated.  It doesn't look like there's 
a lot of documentation for ffproxy on the Internet, from what I found in 
Google...
