Add firewall policy matrix, port forwarding, topology, PoE dashboard
Firewall policy matrix: - VLAN-to-VLAN policies: full, internet-only, blocked, service, custom - Generates both switch ACLs AND OPNsense firewall rules - Printer VLAN preset: one-way access (staff can print, printers can't initiate connections back) on ports 9100/631/443/80 - Additional presets: LAN-access-all, IoT-isolated, Guest-isolated, Camera-NVR-only - Preview endpoint shows generated commands before pushing - Push endpoint applies to both devices with backup + safety check Port forwarding: - Create/delete OPNsense NAT port forwards via API - Tracks rule UUIDs for clean removal - Companion firewall rules auto-created Network topology: - /api/topology returns router, switch, VLANs, port states, devices - Auto-generated from live cached data PoE budget dashboard: - /api/poe/budget parses cached PoE status - Total/used/remaining watts, percent used, per-port draw https://claude.ai/code/session_01Do9bsN39MTuy2GVv7yzSrE
