just do a google for torrent port fowarding. Or look on the official site that you got your torrent client from (probably safer). and then do that he ^^ said. Basically it will have 2 blanks and in the middle it will say "to". Put in the numbers you find. then make sure all the boxes are checked correctly (its obvious what needs to be checked for this) and then hit submit. When your done, even though it wont actually show you which ports you just fowarded, it should work. atleast thats what my linksys does.
you may not get a speed increase, but then again, you may. I know I did this for soulseek and I noticed a speed increase.
