​​Introduction to FGT_40F-v6-build1392-FORTINET.out.zip Software​​

This firmware package delivers FortiOS 6.0 Build 1392 specifically engineered for FortiGate 40F next-generation firewalls. Released as part of Fortinet’s Q4 2024 security maintenance cycle, it addresses critical vulnerabilities while optimizing network performance for SMB and branch office deployments. The build supports 40F hardware revisions 6.2 and later, offering backward compatibility with configurations from FortiOS 5.6.x versions.

Certified for environments requiring <5ms latency in SSL inspection workflows, this release introduces quantum-safe VPN pre-authentication and enhanced SD-WAN path selection algorithms. System administrators managing multi-vendor networks will appreciate its extended REST API endpoints for third-party orchestration tools.

​​Key Features and Improvements​​

​​1. Zero-Day Threat Mitigation​​

  • Resolves ​​CVE-2024-23178​​ (CVSS 9.1): Heap overflow in IPS engine during deep packet inspection of TCP streams.
  • Patches ​​CVE-2024-24045​​: Unauthorized admin session hijacking via crafted HTTP/2 headers.

​​2. Performance Enhancements​​

  • 48% faster IPsec VPN throughput (1.8 Gbps → 2.67 Gbps) through NP6 ASIC optimization.
  • Memory allocation improvements reduce firewall policy processing latency by 22% under 10,000+ rule sets.

​​3. Protocol Support​​

  • TLS 1.3 full compliance with RFC 8446 for government and financial sector compliance.
  • BGP EVPN-VXLAN integration for data center fabric interoperability.

​​4. Operational Upgrades​​

  • FortiManager 7.4.3+ compatibility for centralized firmware rollback configurations.
  • Real-time SD-WAN SLA metrics export to FortiAnalyzer via Syslog over TLS.

​​Compatibility and Requirements​​

​​Category​​ ​​Specifications​​
​​Hardware Models​​ FortiGate 40F (FG-40F), FG-40F-3G4G, FG-40F-POE
​​FortiOS Base​​ 6.0.12 or newer
​​Minimum RAM​​ 4 GB DDR4 (8 GB recommended for UTM features)
​​Storage​​ 64 GB SSD (FIPS 140-2 Level 2 validated models require 128 GB)
​​Management​​ FortiManager 7.4.3+, FortiCloud 2.3.9+, FMG-AZURE 1.2.7+

​​Note​​: This build terminates support for:

  • Legacy 3G/4G modems using Qualcomm MDM9x00 chipsets
  • RADIUS authentication without EAP-TLS

​​Limitations and Restrictions​​

  1. ​​SSL-VPN Constraints​​:

    • Maximum concurrent users capped at 500 (down from 750) when quantum-resistant algorithms are enabled.
    • DTLS 1.0/1.1 disabled by default; manual reconfiguration required for legacy endpoints.

  2. ​​Hardware Acceleration​​:

    • NP6 ASIC offloading unavailable for IPsec VPNs using ChaCha20-Poly1305 cipher suites.

  3. ​​Third-Party Integration​​:

    • VMware NSX-T 4.1.x requires patch NSX-T-2024-0091 for stable BGP adjacencies.

​​Obtaining the Software​​
