1. Introduction to FGT_60D_POE-v6-build0231-FORTINET.out

This firmware package delivers critical security updates and network optimization for FortiGate 60D-POE devices with Power over Ethernet capabilities. Designed for small-to-medium branch office deployments, build 0231 addresses CVE-2024-21762 – a high-risk SSL-VPN vulnerability rated 9.6 CVSS that could enable unauthorized administrative access bypass.

Exclusively compatible with FortiGate 60D-POE (FG-60D-POE) hardware, this Q2 2025 release maintains backward compatibility with FortiOS 6.0.10 through 6.0.18 configurations. The update aligns with Fortinet’s Extended Security Maintenance program, providing 18 months of critical vulnerability patching for PoE-enabled network infrastructures.

2. Key Features and Improvements

  • Updated FortiGuard IPS signatures detecting DNS-over-HTTPS exfiltration attempts
  • Fixed GUI privilege escalation risk in multi-admin environments

​​Network Performance​​

  • 18% throughput increase for IPsec VPN tunnels (150Mbps → 177Mbps)
  • 20% reduction in PoE switch latency during traffic flooding scenarios
  • Optimized memory allocation for captive portal authentication

​​Protocol Support​​

  • TLS 1.3 full inspection with AES-128-GCM cipher prioritization
  • Enhanced VoIP traffic shaping for SIP/RTP protocols

3. Compatibility and Requirements

Component Specification
Hardware Model FortiGate 60D-POE (FG-60D-POE)
Minimum RAM 2GB DDR3 (4GB recommended)
Storage 32GB SSD free space
FortiOS Baseline 6.0.10 – 6.0.18

​​Release Timeline​​

  • Vulnerability disclosure: 2025-04-15
  • Patch validation cycle: 30 days
  • General availability: 2025-05-15

This build requires prior installation of FortiOS 6.0 MR3 baseline. Incompatible with FGT-60E-POE/50D-POE models due to hardware architecture differences.

4. Limitations and Restrictions

  • No direct upgrade path from FortiOS 5.4.x – requires intermediate 6.0.12 installation
  • Maximum concurrent SSL-VPN users capped at 25 (hardware limitation)
  • Lacks ZTNA 2.0 features available in FortiOS 7.2+ releases
  • PoE budget reduced to 60W total during deep packet inspection
