Well, that is going to be a little rough since most file downloads happen
over the same port as the http traffic (port 80). You could block all ports
besides 80, but they'd still be able to download files that were http links.
You might want to look into setting file permissions or doing some kind of
kiosk-mode on your local workstations.

What I want is that clients cannot, let's say with Internet Explorer or
Mozzila, download files from the internet, but can browse the internet.

You can very easily block certain clients based on either MAC address and/or
IP address. As for the ports, well that depends on the application you want
to block (ie. FTP, Kazaa, web, NNTP, etc).

Hey everyone,
Since I want to spare my download speed, and dont want clients to download
freaking warez, would it be possible to block downloads with iptables for
certain clients???
And if it's possible which ports need to closed?
Thanks in advance,
