host A -- router -- host B
Assuming the router is not acting as a bridge, etc.
When the packet goes from A to the router its
destination MAC will be that of the router interface
it can talk to (it will ARP it's gateway's address).
When the packet goes from the router to host B the
source MAC will be that of the router's interface on
that network.
Not sure on the last one.
