I successfully built and tested a comprehensive FortiGate High Availability (HA) topology, diving deep into both the setup and the underlying mechanics of network resilience.
Here are the key technical highlights from today's lab:
? Overcoming PNETLab Hurdles: Started the lab by troubleshooting and fixing Cisco IOL license and file permission issues within the Linux CLI to get the topology running smoothly.
? Active-Passive HA Cluster: Successfully deployed a FortiGate HA cluster (FG1 & FG2) utilizing heartbeat interfaces to ensure zero downtime and high availability.
?️ Out-of-Band (OOB) Management: Configured a dedicated Management Interface for the Secondary firewall. This crucial enterprise best practice allows for independent monitoring and access to the standby unit without interfering with active data traffic.
