Why does your computer send so many packets? Why not send just one big packet? What do SYN, ACK, FIN, GET mean? Why do some packets have sequence numbers? Why does your computer send packets to the webserver that you requested data from? What do the different colors in the Wireshark packet capture listing mean? Why would your computer get packets that are addressed to another computer? How many packets does your computer send/ receive in a single mouse click when you visit a website? Could you organize or filter the traffic to make it easier to understand? How could blocking all ICMP traffic protect you?  Could you still access some websites with your Port 80 rule enabled? Why? Why would you want to allow incoming (not outgoing) Port 443, but block incoming Port 80? Could malware rename itself in order to get through a firewall? Why would this work?
