I have a satelite downlink, and a modem uplink with a different IP. 
I need all packets being sent out the ppp link to appear as if they are coming from 
the sattelite's address(207.16.45.x). This way any data that is to be returned to the PC
should be received via the satelite link instead of the PPP port(source of the request).

To make things more complicated, I need some form of NAT(Masquerading?) done to packets 
originating from the Ethernet port - destined for the PPP, with return coming from the
sattelite going back to the client on the ethernet LAN.

Is this convoluded enough??

Any Ideas?
