Let's break this down in to the simple network flow before trying to
make things work (namely to make sure I understand what you are wanting
to do).
Let's do a re-draw with some clarifications.

A = Cisco 1
B = Cisco 2
C = HP ProLiant 1
D = Workstation 1
Z = INet client
Note: References to "External" (e) interfaces will be facing up and
"Internal" (i) interfaces will be facing down.
I'm presuming (for the sake of discussion) that you presently you have
globally routable services that appear to be on one or more Ae addresses
that are port forwarded to Ce (and possibly others).
Now it sounds like you are wanting to port forward (one or more of) said
service(s) from Ce to De with out changing any thing on A. So the
traffic flow would be from client Z to Ae to Ce to De and back in the
same direction.
I'm also guessing that you would like all systems to have the capability
(whether or not you use it or firewall it is up to you) to connect to Ce
and have the connection be port forwarded to De. Correct?
Before I go in to how to do this, please let me know if I'm on track or not.
Many thanks for you help
