Not only is this not shorewall related, but you really don't give enough
information to solve your problem. What else is on the router? What kind
of shaping are you trying to do? What software are you using for the
shaping and what is the underlying operating system? It seems like you
ought to be able to do this with the hardware you already have... if you
have plenty of ram and the software configuration is right.
