Urgent help please: Port redirection

I need urgent help on the following:
On my Windows 2003 Server machine, I have 2 network interfaces
connecting to the internet, one is an ethernet card & the other
is an ISDN dialup connection. I would like all traffic on port
8080 to use only the ISDN connection, while traffic on port 80
should use the ethernet connection only. How can I achieve this?
Thanks in advance.

As far as I'm aware, this is not possible without additonal
software/hardware.

Routing is performed on an IP level (address based), and not a TCP level
(port based).
