🧱 Packet Filter Flip: Can You Set the Right Rules?

🧱 Packet Filter Flip: A Boolean Game for Firewall Gurus

Packet filtering rules are easy to mistype or misthink — but what if you practiced those ACLs as a logic game? Packet Filter Flip is a fast-paced interactive challenge where you must correctly set ALLOW or DROP on a stack of simplified iptables-style rules based on traffic scenarios.

🧩 Adjust traffic specifications like src and dport to align with constraints like ‘Allow SSH but drop HTTP.’ Flip the rules, check your logic against real-time feedback, and sharpen your sysadmin brain!

🌓 Includes dark mode toggle and no login required.
