(a) If host 192.168.0.1 sends out a packet with source IP address 192.168.0.1 and source port number 3345, after the packets leaves the router from the public interface, what will be the source IP address and source port number in the packet?

Question: The question is incomplete. See the complete question below;

Consider the following situation using NAT (Network Address Translation), where the router uses one public IP address, 138.76.29.7, for several hosts with private IP addresses. The NAT table already has the information as shown due to previous communications.

Source IP = 208.38.69.1

Source port = 3006

Explanation:

Network Address Translation (NAT) simply means  the translation of one or more local IP address so as to provide internet access to local hosts. In this case, the router uses one public IP address and with private IP address.
