Multi-VLAN Network Segmentation & Trunking Configuration
Engineered comprehensive network subnetwork isolation to eliminate flat network security risks and optimize broadcast domains.
Key Features & Implementation
- 802.1Q VLAN Trunking: Standardized tagged VLAN trunks between core firewalls, distribution switch stacks, and wireless access points.
- Isolated Subnet Boundaries: Separated User (VLAN 200), Server (VLAN 300), Management (VLAN 100), and DMZ (VLAN 301) subnets.
- Firewall Inter-VLAN Inspection: Mandated full deep packet inspection (DPI) on all inter-VLAN routed traffic across the FortiGate firewall cluster.
