The MAC address is in the ethernet header. The IP
address is in the IP header. The port address is in
the UDP or TCP header.
When a router forwards the packet, the ethenet header
is not forwarded. The packet is sent with a new
ethernet header with source and destination MAC
addresses for the next netsegment (or something
completely different because the next segment could
be something completely different. ie. not ethernet).
