I've found exactly the same thing.  Traffic shaping seems to do 
nothing.  Not sure how it works, but I set up the same FTP rule, with no 
results.  Can anyone shed some light on how it works?  Does it only 
limit if something else is trying to use the bandwidth too?  If the 
amount of bandwidth you specify a reserved amount, or a maximum amount?
