1) Go back to just 6881-6889. You certainly don't need all those others
open, no matter what those websites said (probably not a terrific idea
from a security viewpoint, either, I'd think). Be sure to forward both
protocols (TCP and UDP) for all ports within that range, though.
2) Your upload rate is way too high, IMO; I find that allowing it to go
above 20kB/s or so begins to throttle my d/l bandwidth - not just for
BT, but for everything (the u/l bandwidth gets saturated, ACKs and such
cease to get through in a timely manner, d/l speeds suffer). Also, it
seems that a max u/l rate above 12kB/s or so for an individual torrent
rarely provides any real increase in that torrent's d/l rate, so there
probably isn't much point in going higher than that for any one torrent.
