> You can reduce the numbe of open ports --- ftpd does not use 1024-65535B

You can't predict what ports the ftp server uses - my users could be
connecting to any ftp server out there which could select any port above 1024.

I'm not protecting just one host, I'm protecting a whole network, with
possibly services running out there - for example X uses ports around 6000. I
can of course block that, but who guarantees that there isn't some other
software listening on some other port on a users Windoze box?
