A pedido de muitas famílias aqui está uma receita (em ingles) de como resolver o problema do PUA para sistemas Windows:
Nota: terão de alterar as regras indicadas para reflectir as vossas configurações em termos de torrents e afins
The targets of this post are Windows users that want their BitTorrent connections free of Sandvine’s meddling.
The first thing you are going to have to do is install a real firewall, like the Windows port of FreeBSD’s IPFW. Download WIPFW from sourceforge. Unzip the contents into a location where the files can live, like C:Program Fileswipfw.
Run the install-deny.cmd.
Now, you are ready to configure your new firewall. In the folder where you have WIPFW living, you will see a file called wipfw.conf. Open this in your favorite text editor or notepad, if you don’t have a favorite. Replace the contents of this file with the following, substituting 6883 with your BitTorrent port:
# First flush the firewall rules
# Allow all internal (loopback) network communications.
add 100 allow all from any to any via lo*
# Prevent any traffic to 127.0.0.1, common in localhost spoofing
add 110 deny log all from any to 127.0.0.0/8 in
add 110 deny log all from 127.0.0.0/8 to any in
# Drop incoming packets with RST flag on BitTorrent port
# This is what thwarts Sandvine.
add drop tcp from any to me 6883 tcpflags rst
# Setup stateful filtering
add pass all from me to any out keep-state
add count log ip from any to any
# Allow new incoming BitTorrent connections
add allow tcp from any to me 6883
add allow udp from any to me 6883
Open the command prompt and enter net stop ipfw & net start ipfw. Your computer will now be ignoring Sandvine’s methods.
NOTE: In this configuration, WIPFW drops all other incoming connections and allows all outgoing connections.
