As always, thanks for your reply. Sounds like you may have heard this
question once or twice ;) Sorry for being naive.
I understand what you are saying and this makes sense to me. But would
it stand to reason that if you limit the rate of packets in a TCP stream
that the windowing would slow the generation of traffic from the source
host? I understand UDP is another animal all together.
Do pipes in ipfw only effect outbound traffic on an interface?
