Here is an example of a diagram

5. Network Address Translation (16 pts) 1. Diagram (as done in class) a situation in which there is one local area network (LAN), A. LAN A should contain exactly one router (which has the public IP address) and 3 laptops. Depict connections to the public internet using lines connecting to a cloud. 2. Add Wikipedia's webserver to your diagram. Use ping to determine the IP address it actually has in real life. 3. Assign valid IP addresses to each machine in your diagram. LAN A uses 128.64.0.X IP addresses internally 4. A laptop in LAN A is contacting Wikipedia. Indicate which network address translation table will be updated and what change will be made to it. Show the packet header (source and destination IP address + port) as it looks inside A and outside A. Assume the source port is 1080 and the destination port is 80. 5. Wikipedia receives the packet and responds. Show the response packet header as it looks outside A and inside A. Hierarchy of Networks Backbone e-Internet Internet Service Provider T3 Line IXP ISP .
