Absoluttely CORRECT, your description is very very good.

*nod* Now I know that I am on track and that it is safe to go down the path that I was thinking about.

Another goal should be to minimize traffic on C for service running on D.

Hum. This new goal may be problematic. The problem is that A is DNATing traffic to C that you now want to be re-directed elsewhere. So with out re-configuring A, the traffic is going to continue to be DNATed to C. What is better in the long run is to have A DNAT the traffic to B which will then DNAT the traffic in to D.

How much control do you have over B?

Can you request changes be made to A on your behalf?

I recently helped someone else on this list with a similar scenario. However in their scenario both C and D were directly connected to the internet via different providers and there was a VPN between C and D. The goal was to port forward connections originally to C over to D and have the replies go back through C and out to the original client. We ended up getting things to work exactly as they needed to. However all the traffic for the forwarded service was still passing through C on its way to D, which you are now wanting to avoid.
