Do you actually have a question?

What you've listed as basic port-forwarding, and is only really valid
when going through a NAT. If you really want to redirect a port to
another machine without going through a NAT (such a when you have a
transparent proxy set up on a machine that is not the firewall), then I
suggest you have a look at the Transparent Proxy HOWTO for how to do
such a thing.
