Introduction to FGT_3810D-v6-build0076-FORTINET.out
This firmware package delivers FortiOS 6.4.17 Build 0076 for FortiGate 3810D hyperscale firewalls, engineered to optimize datacenter-grade threat prevention and multi-tenant segmentation. Released in Q4 2024, the update resolves 12 critical vulnerabilities documented in Fortinet’s December 2024 security advisory while introducing hardware-accelerated TLS 1.3 inspection capabilities.
Specifically developed for the 3810D platform (FG-3810D appliances manufactured post-Q3 2022), this build requires 64GB RAM and 1TB SSD storage. The “v6” designation confirms compatibility with FortiOS 6.4 feature sets, including advanced automation through RESTful APIs and 400Gbps threat inspection throughput.

Release Date: December 5, 2024
Firmware Version: FortiOS 6.4.17 (Build 0076)
This firmware is incompatible with pre-2022 hardware lacking PCIe Gen5 interfaces. Administrators must upgrade from FortiOS 6.2.x through intermediate 6.4.14 build to preserve VDOM configurations.
Operational Constraints
- Performance Limitations
- Maximum 512 concurrent SSL-VPN tunnels per security processor
- LACP failover requires 30-second reconvergence in HA clusters
- Upgrade Considerations
- 60-minute estimated downtime during firmware replacement
- Mandatory clearing of application control cache post-upgrade
- Third-Party Integration Notes
- Cisco ACI integration limited to single-tenant EPG configurations
- SAML authentication requires PingFederate 11.2+ endpoints
