3. 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. NAT translation table LAN side addr WAN side addr 138.76.29.7, 5001 10.0.0.1, 3345 138.76.29.7, 5002 10.0.0.2, 3345 138.76.29.7, 5003 10.0.0.3, 3365 138.76.29.7 10.0.0.4 10.0.0.1 10.0.0.2 10.0.0.3 If host 10.0.0.1 sends out a packet with source IP address 10.0.0.1 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? Assume that a packet (from the public Internet) with source IP address 200.100.8.7 and source port number 4000 arrives at the router. Also assume that the packet's destination address is 138.76.29.7 and the destination port is 5003. 1. Which host will the router send the packet to? 2. When the destination host receives the packet, what is the source IP address in the packet? What's the source port number in the packet? What's the destination IP address in the packet? What's the destination port number in the packet? 3.
