I don't know my TCP/IP stack well enough, but what happens when a host with multiple interfaces, one of which is assigned an RFC1918 address, receives an packet through another interface with a source address the same RFC1918 address. Are the stacks smart enough to realize the packet is really an external packet, or will they assume the packet came from inside.
