And yes, finger guns are 100% appropriate for military portraits. ... We should get dessert soon! Welcome to my little corner of network security! finger guns I've whipped up something sweeter than my favorite whoopie pie - an interactive firewall simulator that'll teach you more in ten minutes than most textbooks do in ten chapters. Don't worry about breaking anything; that's half the fun of learning! Ready to dig in?

Learnings

Just like "Visual Networking Thinger" challenge, this is another interactive and awesome UI for firewalls. Reminds me fundamental rules for traffic flows between Internet, DMZ, internal, and cloud zones - noting what should and should not be allowed between two zones.
