Problem # 5 (11 points): Consider the following network. Hosts A, B, C, and D belong to a private network hidden behind the NAT router RI, whereas hosts E and F belong to the Internet. Suppose that host A wants to send a TCP segment to host F, and host A will receive a reply TCP segment back from host F. Assume that just before the start of the transmission that the ARP tables of router R1 and all hosts are complete while the ARP table of router R2 is empty. Assume further that all switch tables are empty.
