• Data center uplinks and segmentation
• High-throughput VPN termination and site-to-site connectivity
• Networks requiring a combination of copper and fiber interfaces

Key specifications

• Ports: 18 Gigabit Ethernet RJ45 ports
• Fiber slots: 8 Gigabit SFP slots
• High-speed uplinks: 4 10 Gigabit SFP+ slots
• Form factor: rack-mountable appliance suitable for enterprise racks
• Primary functions: firewall, VPN and traffic control consolidated on a single appliance

How to use

Install the FortiGate-120G into a standard rack and connect copper or fiber links to the corresponding RJ45, SFP or SFP+ ports according to your network topology. Use the vendor-provided management interface to configure firewall policies, VPN tunnels and traffic shaping rules. Integrate the appliance with existing authentication, logging and monitoring systems for centralized administration and consistent security policy enforcement.

Usage recommendations

Place the appliance at the network edge or between core and distribution layers to maximize its firewall and VPN capabilities. Match SFP and SFP+ transceivers to your fiber type and distance requirements, and plan port assignments to separate management, WAN, and internal traffic. Keep firmware and security signatures up to date and monitor throughput to ensure the appliance meets your performance and availability needs.
