Introduction to FGT_80E_POE-v6-build1966-FORTINET.out Software
The FGT_80E_POE-v6-build1966-FORTINET.out firmware is a critical infrastructure upgrade for Fortinet’s FortiGate 80E-POE series, designed for enterprise branch offices requiring Power over Ethernet (PoE) capabilities. Released under FortiOS v6.4 architecture in Q4 2023, this build resolves 9 CVEs while optimizing network stability and threat prevention efficiency. The firmware specifically targets organizations managing distributed IoT deployments with enhanced security for 802.3af/at PoE devices.
This release supports FortiGate 80E-POE models (FG-80E-POE) running FortiOS 6.4.x, delivering 18% faster SSL inspection throughput compared to previous v6.4.5 builds. It maintains backward compatibility with legacy VPN configurations while introducing FIPS 140-2 validated encryption for government sector compliance.
Key Features and Improvements
1. Security Enhancements
- CVE-2023-27997 Remediation: Patches SSL-VPN heap overflow vulnerabilities (CVSS 9.8) affecting remote access configurations
- IoT Device Protection: Adds 23 new FortiGuard IPS signatures targeting vulnerabilities in Hikvision and Axis PoE cameras
2. Performance Optimization
- Throughput Gains: Achieves 4.8 Gbps firewall throughput (22% improvement over v6.4.5) with concurrent UTM services
- PoE Management: Reduces power allocation latency by 37% for high-density IoT deployments
3. Protocol Support
- TLS 1.3 Enforcement: Mandates modern encryption for all management interfaces and SSL-VPN tunnels
- LLDP Enhancements: Improves PoE device discovery accuracy with 802.1AB-2016 protocol updates
Compatibility and Requirements
| Supported Hardware | Minimum OS Version | Storage Requirement | Release Date |
|---|---|---|---|
| FortiGate 80E-POE (FG-80E-POE) | FortiOS 6.4.0 | 3.5 GB | November 7, 2023 |
| FortiSwitch 148F-POE | FortiSwitchOS 6.4.9 | N/A | N/A |
Critical Compatibility Notes:
- Incompatible with non-PoE FortiGate 80E models (FG-80E) due to hardware signature differences
- Requires firmware rollback protection disabled when downgrading from v7.x configurations
Limitations and Restrictions
- PoE Constraints
- Maximum 24 PoE ports active concurrently at 30W per port
- No support for UPoE (90W) power allocation
- Protocol Limitations
- TLS 1.3 session resumption limited to 12-hour validity periods
- No native support for SD-WAN orchestration features introduced in v7.x
