2. Consider the network illustrated in Figure 1 - A NAT configuration. The router has a private IP address (192.168.0.1), and a public IP address (114.24.10.1): What do the terms private IP address and public IP addresses mean? (4 marks) (ii) Explain the purpose and operation of Network Address Translation (NAT) from the perspective of the Router. In your answer identify which addresses the router keeps track of to facilitate NAT. (5 marks) (iii) Assuming that Host 192.168.0.55 is communicating with the Host 147.252.25.70, identify separately the source and destination IP addresses for each packet/datagram labelled A, B, C and D. (6 marks) (iv) Can the Host 147.252.25.70 initiate communications with Host 192.168.0.55? If not, why not?
