I'm trying to increase the speeds of my Bit Torrent downloads by opening ports 6881-6889 but for some reason I can't seem to get the configurations right. I checked it on the GRC website (https://www.grc.com/x/ne.dll?bh0bkyd2) but it keeps on giveing me values with Stealth values for it. I'm using a wireless ADSL router "Hurricane 900W" by Prolink. Does anyone know how to open these ports?
