FortiGate HA Setup: Active-Passive, NAT Basics
This week at Null0 Labs, we swap out the Palo Altos for a pair of FortiGates and dive into Active-Passive High Availability with clean NAT flows and real failover tests.
🔧 What’s covered:
• Active-Passive HA pairing on FortiGate
• Source NAT & Destination NAT configuration
• Failover testing: full device shutdown
• Load balancing demo
Whether you're building a lab or prepping for production, this walkthrough gives you a solid foundation for FortiGate HA deployments.
