    A packet is first pushed through the IP "stack" and ultimately through 
the route table.  The route table will determine the BEST route for that 
packet based on the Destination address.  The Source address of that 
packet will take on the IP address of whichever interface the routing 
table found to be the best route.

    Most systems have but one ethernet, so we become accustomed to the 
"machine" using the IP address of that interface.   When you have two or 
more ethernet interfaces, the above stated process becomes more obvious.

    For example, I have interfaces 216.144.208.26 *and* 44.102.1.250.   If 
I attempt to reach a host in the 44/8 network, my Source address will 
become 44.102.1.250.   If I try to reach anything else, my route table 
indicates to use the 216.144.208.26 interface and my Source address 
becomes that.

    Hope this has helped.
