Release Date: September 15, 2024
Firmware Version: FortiOS 6.0.6 (Build 0076)
This firmware is incompatible with pre-2021 hardware revisions lacking TPM 2.0 security chips. Administrators must upgrade from FortiOS 5.6.x through intermediate 6.0.4 build first to ensure configuration integrity.
Limitations and Operational Considerations
- Functional Constraints
- Maximum 128 concurrent SSL-VPN users per VDOM
- LAG interface failover requires manual intervention in HA clusters
- Upgrade Precautions
- 35-minute estimated service interruption during firmware replacement
- Web filtering cache must be cleared post-installation
- Third-Party Integration Notes
- SAML authentication requires Azure AD v2.1 endpoints
- Cisco ACI integration limited to single-tenant configurations
