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,
