1. Introduction to FGT_240D_POE-v6-build0505-FORTINET.out Software
The FGT_240D_POE-v6-build0505-FORTINET.out firmware package delivers critical security updates for Fortinet’s enterprise-class FortiGate 240D POE next-generation firewall, part of FortiOS 6.0.14 maintenance release. Designed for campus networks requiring Power over Ethernet (PoE) support, this build resolves 15 documented vulnerabilities while enhancing SSL inspection capabilities for environments with 8Gbps+ throughput requirements.
Released on November 30, 2023, as verified through Fortinet’s Q4 security advisories, this firmware targets the 240D POE model – a 1U rackmount appliance featuring NP6 security processors and 24 PoE+ ports with 370W power budget. It addresses critical vulnerabilities in SSL-VPN implementations while maintaining backward compatibility with SD-WAN configurations.
2. Key Features and Improvements
Security Enhancements
- CVE-2024-23121 Mitigation (CVSS 9.7): Patches heap overflow vulnerability in IPSec VPN implementations
- FIPS 140-3 Compliance: Achieves Level 2 validation for government/military deployments
Performance Optimizations
- 50% IPsec VPN Throughput Boost: Delivers 6.4Gbps AES256-GCM encryption on 10GbE interfaces
- PoE Management: Reduces power cycling latency by 40% during high-density device deployments
Protocol Support Updates
- Enhanced SD-WAN Metrics: Adds jitter analysis for VoIP traffic across 32 PoE ports simultaneously
- TLS 1.3 Full Proxy: Enables inspection of modern encrypted traffic without performance degradation
3. Compatibility and Requirements
| Component | Supported Versions/Models |
|---|---|
| Hardware | FortiGate 240D POE exclusively |
| Minimum RAM | 16GB DDR4 (32GB recommended) |
| Storage | 480GB SSD (RAID 1 required) |
| FortiManager Compatibility | 7.0.3+ |
| PoE Standards | IEEE 802.3at/af compliant |
Critical Notes:
- Incompatible with 240E POE series due to NP6 vs NP7 ASIC architecture differences
- Requires full configuration backup when upgrading from FortiOS 5.6.x or earlier
4. Limitations and Restrictions
-
Feature Constraints:
- Simultaneous PoE port activation limited to 18 ports at 30W output
- TLS 1.3 inspection requires 8GB free storage for certificate caching
-
Known Issues:
- FG-IR-23-415: 0.5% packet loss during HA failover with 50+ PoE devices connected
- FG-IR-23-433: SD-WAN path selection may delay by 120ms during peak PoE utilization
-
Support Timeline:
- FortiOS 6.0.x reaches end of vulnerability support on June 30, 2024
