If I understand what you want to do, I believe you can do this with IP tables, telling it to change the "source" IP of the outgoing packet to whatever you want it to be.

I did this for a customer, couple years back, but don't have my hands on the commands.  You might be able to google it.

If I can dig up the commands, I will post them.
