Uninstall any torrent client you have. then you install Bittornado from
www.bittornado.com.
now download torrent headers from torrent sites and save them on your desktop. and open the torrent header with 'bittornado'. if its a live torrent and has a good number of seeders then your download speed will be enough to download a 100MB file in 20mins.
And don't mess with ports or their numbers unless you r totally acquainted with them.
