Multi-VLAN healthcare network with dual-core switching, FortiGate NGFW security, and segmented access across six floors. Traffic flows from Internet through fiber modem and ISP router to FortiGate captive portal, then distributes via redundant DGS-3130 core switches to six floor-level access switches serving management, servers, medical imaging, wired users, WiFi staff, guest, and quarantine VLANs. This architecture isolates critical medical systems, guest traffic, and suspicious devices while maintaining high availability through core switch redundancy. Fork this diagram to customize VLAN assignments, add additional floors, or integrate your own access control policies. The design demonstrates healthcare network segmentation best practices required for HIPAA compliance and operational resilience.
