(4 pts.) Suppose the router (R1) in the gure is con gured using network address translation (NAT). The IP of each interface is shown in the gure. The host shown in the local network connects to the server on Internet using TCP. (a) What is the destination IP address in packets (that belong to the TCP connection) received from the Internet by R1? (b) What is the source IP address in packets (that belong to the TCP connection) received by the host? (c) What is the source IP address in packets (that belong to the TCP connection) received by the server? (d) What is the destination IP address in packets sent by the server to the host when they pass through R2?
