Hi, in my network users are increasing the amount of peer-to-peer traffic (e-mule, winmx), how can I deny the above traffic? I'm using iptables and squid on my linux firewall, but I don't know if there's a specific port to lock or something else I can use to recognize the "bad" packet in the network traffic.
