qBittorrent is awesome. In Options/Connection, fill in the port you forwarded in AirVPN Uncheck "Use UPnP" Unhceck "Use different port on each startup" In Options/BitTorrent, Check Enable DHT" Uncheck "Use a different port for DHT and BitTorrent" Check Enable Peer Exchange (PeX) Check Enable Local Peer Discovery (optional, based on seranecks post below) Encryption Mode: Prefer encryption Uncheck Enable anonymous mode Uncheck Torrent Queueing (my preference - use the entire ISP pipe for concurrent torrenting) In Options/Advanced, ensure the "Network Interface" is set to "tun0" so it will exclusively use the AirVPN Tunnel. (if on Windows, find the Local Area Connection number that references your tunnel adapter. You can find this out by going to a command prompt, running ipconfig /all, and look for the adapter with the 10.x address). Restart qBittorrent, and you should be good to go.
