Downloading torrent behind NAT
To download torrent files when system is behind NAT, 'uTorrent' windows based torrent client can be used. uTorrent should be configured with following connection settings:
- Disable uPnP, NAT-PMP, etc. everything except creating exception in Windows Firewall.
- Allow direct connections from system IP outside through perimeter firewall
- Do not configure any proxy server.
