P2P-Block offers the ability to allow or ban peer-to-peer traffic of certain file sharing programs. Supported applications, peer-to-peer networks or protocols are directly selectable on the list and can be configured individually without any effects on other items or firewall rules.
Please note, P2P-Block cannot affect encrypted traffic! To block encrypted peer-to-peer traffic you will have to create additional firewall rules.
The last two lines are the legend:
Topics selected are allowed, topics not selected are blocked.
