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).

  downloads

  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,
