PeerGuardian 2.0-beta-6c

"A free firewall specially created for P2P programs"
PeerGuardian is a tool to protect your computer from intruders who want to sneak through your firewall ports, specially designed for those users who use a download program based on peer to peer. You know, you make available to other users a folder on your computer with files that they can download using a suitable program and at the same time you do the same with their computers.
This tool works by blocking ports and all TCP/IP connections that are unknown to you.
It is a powerful program but it will hardly occupy space in your memory and will not affect the performance of your computer at all.
