c) Given 04 hosts in a LAN, with private IP addresses 192.168.1.10, 192.168.1.11, 192.168.1.12, and 192.168.1.13. Consider that the LAN is behind a NAT'd router which is between the 04 hosts and the Internet. The IP datagrams sent from, or destined to, these 04 hosts must pass through the NAT router. The router's interface on the LAN side has IP address 192.168.1.254, while the router's address on the Internet side has IP address 131.122.102.202. Suppose, the host with IP address 192.168.1.13 sends an IP datagram to a host 129.108.107.188 that resides in the Internet. The source port is 4404, and the destination port is 80. Answer the following questions: i. ii. iii. What are the source and destination IP addresses for this datagram, when the datagram that is sent by the host hasn't reached the router yet? What are the source and destination IP addresses of the datagram, when the datagram is transmitted by the router? Is the source port changed? Yes or No. What are the source and destination IP addresses of the datagram, when the datagram is just about to be received by the host via the router?
