1. Considerthe following situation using NAT (Network Address Translation),where the router uses one public IP address, 208.38.69.1, forseveral hosts with private IP addresses. The NAT table already hasthe information as shown due to previous communications.

1. If host 192.168.0.1 sends out a packet with source IP address192.168.0.1 and source port number 3345, after the packets leavesthe router from the public interface, what will be the source IPaddress and source port number in the packet?

Assume that a packet (from the public Internet) with source IPaddress 250.10.0.9 and source port number 3000 arrives at therouter. Also assume that the packet’s destination address is208.38.69.1 and the destination port is 3008.

2. Which host will the router send the packet to? (Please specifythe IP address of the host)

3. When the destination host receives the packet, what is thesource IP address in the packet? What’s the source port number inthe packet? What’s the destination IP address in the packet? What’sthe destination port number in the packet?

2. We used the following diagram to demonstrate IPv4-to-IPv6tunneling.

1. Is Datagram 1 an IPv4 datagram or an IPv6 datagram (i.e., doesit have IPv6 header or IPv4 header)? Is the source address A anIPv4 address or an IPv6 address?

2. Is Datagram 2 an IPv4 datagram or an IPv6 datagram (i.e., doesit have IPv6 header or IPv4 header)? Is the source address B anIPv4 address or an IPv6 address?

3. Is Datagram 4 an IPv4 datagram or an IPv6 datagram (i.e., doesit have IPv6 header or IPv4 header)? Is the destination address Fan IPv4 address or an IPv6 address?
