Most likely because MAC addresses are only used in a brodcast domain,
ie it does not travers routers, because the router is an intermediate
that needs to recevie the traffic before "forwarding" it out on the
right interface.
And there is nothing that says all points between 2 PC's on 2
diffirent places on the internet uses Ethernet all the way to
communicate.

Or are you talking about your local lan?
