Project 2: Firewall implementation The objective of this project is two-fold: learning how firewalls work, and setting up a simple firewall for a network. You will first implement a simple stateless packet-filtering firewall, which inspects packets, and decides whether to drop or forward a packet based on firewall rules. Through this implementation task, you can get the basic ideas on how firewall works. Lab Report You need to submit a detailed lab report, with screenshots, to describe what you have done and what you have observed. You also need to provide explanation to the observations that are interesting or surprising. Please also list the important code snippets followed by explanation. Simply attaching code without any explanation will not receive cred
