Also, Im not sure what to put in as the port range.
I don't use torrent software anymore, but if I wanted to get my uTorrent going, I would first set a port in uTorrent, options->, preferences-> connecton, such as
Then in my router, I would forward that port from the Wan side to the port on the PC. In this case, it would be outside port 28155 to internal port 28155, both UDP and TCP. If I have multiple PCs then each PC would get a different port in its torrent software. So, on a second PC, I would use a different port than 28155. On the same PC, but a different client, such as BitComet, I would use a different port. I would keep the Wan port and the Lan port the same when making the forwarding rule in the router.
That would take care of the torrents. This client also has DHT, but I don't know whether the port forwarding would also take care of that, or whether additional configuration is necessary. Didn't see it in the directions.
If your router has UPnP, then UPnP can take care of the port forwarding. My router does not have UPnP, so can't use it. If I had UPnP, I would use the random port option in conjunction with UPnP, which I consider its best feature.
