Or setup a transparent proxy for port 80.  The users laugh heartily that
they have outsmarted their System Administrator, and avoid the proxy,
while all the while all http data is passing through the proxy unnoticed
;)

A transparent proxy is useful as the clients (IE, Mozilla, etc) need not
be configured to use any http proxy.  They use it without ever knowing.

This is also accomplished using iptables.  I'd recommend the original
poster looking at this after he's got the rest of it running.

Good explanation Russell.
