OK. If that's the case, then the --mac-source target would 
only work on a LAN, not over the ethernet. This would mean 
thatthe --mac-sourse target has very limited use - only on 
local LANs.

But there is still a place for a MAC address. How can I  put 
one in the packet on the client side? This would allow me to 
use it over the internet.
