The figure below shows a set-up with a private IP network and public NAT box. The NAT box has a public address of 128.6.13.3. and private IP address of 192.168.1.1. The two hosts attached to the same network as the NAT box have the IP addresses as shown

A. (2 points) Host A in the figure sends a TCP SYN packet to IP address 216.109.118.73, port 80, with its local port set to 6798. Show the resulting entry in the NAT box (you make have to improvise some of the fields, anything consistent is OK). B. (2 points) Supposed just after part (A) above, host B sends a SYN packet to the same destination address and port, with its local port also set to 6798. Show the resulting entry in the NAT box (you make have to improvise some of the fields, anything consistent with part (A) is OK). C. (2 points) What will the host at 216.109.118.73receive for the destination,source addresses and destination,source ports for (A) above? D. (4 points) Describe how the ACK for SYN sent in part (A) will reach host A, even though host As network number (192.168.2) is not in any intermediate routers on the Internet.
