Cybersecurity:

You have set up a Wi-Fi home network which connects to the Internet through a Network Address Translation (NAT) router. Your Laptop is connected to the home network and has IP address 192.168.0.15.

a) (5 points) Assume Your Laptop sends a TCP SYN packet to the www.depaul.edu server. When this TCP SYN packet goes through the NAT router, what changes will this router make to this packet?

b) (5 points) The www.depaul.edu server sends back a TCP SYN/ACK reply packet to Your Laptop. When this packet goes through the NAT router, what changes will this router make to this packet?

c) (5 points) You may set a DMZ IP address on the NAT router. What is the purpose of this DMZ IP address? When will it be used by the NAT router?
