⚙ Under the hood

Build an ordered firewall rule list (allow/deny by protocol, source IP/CIDR and destination port) and watch live packet traffic get checked top-to-bottom, first-match-wins, until each packet is allowed or blocked at the wall; send hand-crafted test packets and see the shadowed-rule and default-deny counters update live.
