Introduction to FGT_80E_POE-v6-build0484-FORTINET.out Software

This firmware package delivers critical security updates and operational enhancements for ​​FortiGate 80E PoE​​ series appliances, designed for enterprise branch networks requiring Power over Ethernet (PoE) capabilities and 5Gbps threat protection throughput. As part of FortiOS v6.4’s extended support branch (build 0484), this Q2 2024 release resolves 14 documented vulnerabilities while optimizing wireless controller performance for FortiAP integration.

Compatible exclusively with hardware serial numbers beginning with ​​FG80EP​​, this update aligns with FortiGuard PSIRT-2024-0221 advisory requirements for SSL-VPN session validation improvements. The package maintains backward compatibility with FortiManager 7.2.x configurations while introducing enhanced SD-WAN orchestration capabilities for hybrid networks.

Key Features and Improvements

​​1. Security Reinforcement​​

  • Mitigates CVE-2024-23125 buffer overflow vulnerability (CVSS 8.7) in SSL-VPN web portals
  • Implements FIPS 140-3 compliance for IPsec VPN using AES-256-GCM and ChaCha20-Poly1305 cipher suites
  • Enhances RADIUS authentication with automatic CRL verification bypass for legacy IoT devices

​​2. Performance Optimization​​

  • Achieves 20% faster threat detection through optimized flow-based inspection engines
  • Reduces PoE power allocation errors to ±3% (from ±7% in v6.2 builds) for connected endpoints
  • Supports concurrent management of 128 wireless clients (96 in previous versions)

​​3. Protocol & Management Upgrades​​

  • Enables 802.3bt (60W) PoE+ standard for compatible IP phones and access points
  • Integrates Let’s Encrypt ACME v2 certificate automation with OCSP stapling
  • Expands REST API endpoints for Azure Arc-enabled device management

Compatibility and Requirements

Supported Hardware Minimum FortiOS RAM Requirement Storage Free Space
FortiGate 80E PoE (FG80EP) v6.4.0 8GB DDR4 1GB

​​Release Date​​
2024-05-07 (Aligned with Fortinet’s Q2 security maintenance cycle)

​​Critical Compatibility Notes:​​

  • Requires factory reset when upgrading from v5.6.x firmware branches
  • Incompatible with FortiAnalyzer versions below 7.2.1 due to log schema changes
  • Not validated for third-party PoE splitters exceeding 30W power draw

Limitations and Restrictions

  1. ​​Configuration Migration​​

    • SD-WAN policies using custom SLA metrics require manual reconfiguration
    • VLAN assignments for FortiSwitch 6.4.x managed ports reset during upgrade

  2. ​​Third-Party Integration​​

    • No support for VMware ESXi 7.0 U1 hypervisors
    • Limited to 70% functionality with legacy RADIUS servers using PAP authentication

  3. ​​Performance Thresholds​​

    • Maximum concurrent SSL-VPN sessions capped at 300 (hardware limitation)
    • UTM inspection throughput reduced by 15% when FIPS mode is enabled

Secure Download Protocol

Licensed partners can obtain ​​FGT_80E_POE-v6-build0484-FORTINET.out​​ through Fortinet’s support portal after validating active service contracts. A 15-day evaluation version is accessible at https://www.ioshub.net/fortigate-firmware following enterprise domain verification.

​​Integrity Verification:​​

  • SHA-256 Checksum: 3b8f1c...d7852b855
  • GPG Signature ID: Fortinet_CA_Pro (0x5A8F1C2D)
