A device D1 with an IP address of 192.18.24.1 and a MAC address of 2F-1A-EF-37-12-E2 is located in a LAN (LAN 1) that is connected to the internet through a router with an interface IP address of 192.18.1.12 and a MAC address of 02-44-56-1A-2B-3C. This router supports another LAN (LAN 2) through an interface with an IP address of 12.120.12.18 and a MAC address of 87-24-35-46-61-0C. A device D2 residing in LAN 2 has an IP address of 10.120.12.34 with a MAC address of 3A-85-6D-24-B2-11. If device D1 is sending a message to device D2, determine the source and destination addresses at the IP layer and the data link layer of the datagrams from D1 to D2.
