The figure below illustrates an IPsec configuration in the tunnel mode with the ESP header, in which the IPsec gateways are located at R1 and R2. Answer the following True/False questions, and briefly justify your answers. A. [2 points] When a host in 172.16.1/24 sends a datagram to an Amazon.com server, the router R1 will encrypt the datagram using IPsec. B. [2 points] When a host in 172.16.1/24 sends a datagram to a host in 172.16.2/24, the router R1 will change the source and destination address of the IP datagram. C. [2 points] Consider sending a TCP segment from a host in 172.16.1/24 to a host in 172.16.2/24. Suppose the acknowledgment for this segment gets lost, so that TCP resends the segment. Because IPsec uses sequence numbers, R1 will not resend the TCP segment.
