Student Name: : 15 miu below in which three bosts, with private IP addresses 10.0.1.12, network behind a NATted router that sits between these three being sent from, or destined to, these three hosts must Marks: 10 Q1: Consider the scenario which 10.0.1.17, 10.0.1.19 are in a local hosts and the larger Internet. IP datagrams pass through this NAT router. intertace while the router's address on the Internet side has IP adre address on rthe route's interfiace on the LAN side has IP address 10.0.1.28, WAN Side addr LAN Side addr 10.0.1.12 10.0.1.28 0.0.1.17 135 122 204 207 10.0.1.19 Suppose that the host with IP address 10.0.1.17 sends an IP datagram destined to host 128.119.173.188. The source port is 3423, and the destination port is S0 the datagram at step I, after it has been sent by the host but before it has reached the router. What are the source and destination IP addresses for this datagram? What are th source and destination port numbers for the TCP segment in this IP datagram? Now consider the datagram at step 2, after it has been transmitted by the NATted router. What are the source and destination IP addresses for this datagram? What are the source and destination port numbers generates a new source port number 5163. Specify the entry that has been made in the NAT table. for the TCP segment in this IP datagram? Assume that the NAT Now consider the datagram at step 3, just before it is received by the NATted router. What are the source and destination IP addresses for this datagram? What are the source and destinatior port numbers for the TCP segment in this IP datagram? Last, consider the datagram at step 4, after it has been transmitted by the NATted router but before it has been received by the host. What are the source and destination IP address for thi datagram? What are the source and destination port mumbers for the TCP segment in this IP datagram? Identify the differences in datagram's IP addresses and port numbers between ste and step 4
