Question-1: (15 Marks) 1) Your company has recently been expanded and currently 40 users of your company need simultaneous access to the internet. However company has only one public IP address. The network diagram of the company is presented below. Consider an example situations when three computers in switch-1 are communicating with remote server at the same time using one public IP. Assume PC-1 under switch-1 is using TCP port (1020) for this example. The public IP is assigned to the border routers (NAT router) serial interface. Explain (for PC-1) how packet is sent to and received from the destination remote server by PC-1 through the steps: 1. source and destination addressesin outgoing packetsfrom PC-1; 2. how router keeps track of incoming packet from remote server and forwards to correct sources with private IP inside the company host by using routers entries.
