It sounds like what you want is a transparent proxy.  For a transparent
proxy, your students would have to be "behind" the proxy (i.e. to get to
the outside world their packets would have to pass through the proxy
machine)  I think people have set up FilterProxy in this way before (via
port redirection using ipchains/iptables).

If your students are not "behind" the proxy, then the only thing you can
do is to have them put in proxy settings for netscape.  (otherwise,
their web requests would not be routed to the computer the proxy is
running on)
