If it's FreeBSD bandwidth limiting and packet dropping are all done through
the convienient ipfw command, all that is required for it to work is a KLM
called 'DUMMYNET' must be compiled in when you build your kernel, Check the
MAN page for ipfw for well structured and easy to understand explainations
on how to get it working in your situation(i'm stupid, and I got it to
work!)

Dummynet does it all with simplicity and ease, specify a pipe that you want
to be able to limit then simply modify the BW and Packetloss settings on
that pipe.

As someone mentioned Linux will do this with the standard 2.4.? kernel, I'll
add to that and tell you that FreeBSD can do it with the standard kernel
too(recent versions of freebsd), but without knowing what OS your working
with I cannot help any further.
