Introduction to FGT_240D_POE-v6-build0528-FORTINET.out

This firmware release (build0528) provides critical security updates and hardware-specific optimizations for FortiGate 240D-POE firewalls, aligning with FortiOS 6.4.5 architecture. Designed for distributed enterprise networks requiring Power over Ethernet (PoE) capabilities, it addresses 9 high-risk vulnerabilities while improving PoE management efficiency. The firmware exclusively supports FortiGate 240D-POE hardware (FG-240D-POE), released by Fortinet in Q3 2024 to extend the lifecycle of legacy PoE-enabled security appliances.

Key Features and Improvements

  1. ​PoE Management Enhancements​
  • Dynamic power budgeting prioritizes critical devices (IP cameras, VoIP phones) during power shortages
  • 30% reduction in PoE port initialization time compared to FortiOS 6.4.3
  • Added support for IEEE 802.3bt (90W) devices on ports 1-24
  1. ​Security Updates​
  • Patched SSL-VPN authentication bypass vulnerability (CVE-2024-3265)
  • Fixed buffer overflow in IPS engine affecting PoE-connected IoT devices (CVE-2024-4122)
  • Updated FortiGuard IPS signatures covering 27 new exploit patterns
  1. ​Performance Optimization​
  • 18Gbps throughput achieved at 85% CPU utilization via NP6 processor optimizations
  • 40% faster HA failover times in clustered configurations
  • Reduced memory consumption by 22% during peak traffic loads
  1. ​Management Integration​
  • Full compatibility with FortiManager 7.4.3+ for centralized PoE policy management
  • Supports FortiAnalyzer 7.4.1+ for real-time PoE device activity logging
