🚦 Interactive Network ACL Visualizer – Simulate & Test Firewall Rules with Drag-and-Drop
Visualizing how network access control lists (ACLs) affect packet flow is crucial in both security design and troubleshooting. The Interactive Network ACL Visualizer enables IT admins, network engineers, and security analysts to simulate ACL rule evaluation through an intuitive drag-and-drop interface that’s fully client-side and responsive.
⚙️ Features & Benefits
- Real-time simulation of ACL rule matching on dropped packets
- Interactive rule creation with support for
allowanddenylogic - Reorderable rule list and evaluation stack
- IPv4 address matching and port filtering logic visualization
- Dark Mode Toggle for professional GUI comfort
- LocalStorage-powered persistence – reloads your rules
💡 Try simulating SSH access from an internal subnet using ALOW src 192.168.1.0/24 dst 10.0.0.0/8 port 22 to visualize accept-flow behavior.
