​​1. Introduction to FGT_500D-v6-build0457-FORTINET.out Software​​

The ​​FGT_500D-v6-build0457-FORTINET.out​​ firmware package delivers essential security patches and performance upgrades for Fortinet’s enterprise-class FortiGate 500D next-generation firewall, part of FortiOS 6.0.14 maintenance release. Designed for high-traffic data center environments, this build resolves 11 documented vulnerabilities while enhancing SSL inspection capabilities for networks requiring 40Gbps+ throughput.

Released on December 15, 2022, as verified through Fortinet’s Q4 security advisories, this firmware targets the 500D chassis system – a 2U rackmount appliance featuring CP8 security processors and 160Gbps firewall throughput capacity.

​​2. Key Features and Improvements​​

​​Security Enhancements​​

  • ​​CVE-2022-40684 Mitigation​​ (CVSS 9.6): Patches critical authentication bypass vulnerability in administrative interfaces
  • ​​SSL-VPN Hardening​​: Implements FIPS 140-2 compliance for government/military network deployments

​​Performance Optimizations​​

  • ​​40% IPsec VPN Throughput Increase​​: Achieves 25Gbps AES256-GCM encryption on 40GbE interfaces
  • ​​Memory Management​​: Reduces resource contention in configurations with 1,000+ concurrent security policies

​​Protocol Support Updates​​

  • ​​Enhanced SD-WAN Metrics​​: Adds packet loss/latency tracking for Microsoft Teams and Zoom traffic profiles
  • ​​TLS 1.3 Compatibility​​: Partial proxy support for modern encryption standards in HTTPS inspection

​​3. Compatibility and Requirements​​

​​Component​​ ​​Supported Versions/Models​​
Hardware FortiGate 500D exclusively
Minimum RAM 32GB DDR4 (64GB recommended)
Storage 480GB SSD (RAID 1 required)
FortiManager Compatibility 6.2.3+
FortiAnalyzer Compatibility 6.2.3+

​​Critical Notes​​:

  • Incompatible with 500E/F series due to NP6 vs NP8 ASIC architecture differences
  • Requires full configuration backup when upgrading from FortiOS 5.6.x or earlier

​​4. Limitations and Restrictions​​

  1. ​​Feature Constraints​​:

    • SD-WAN application steering policies created in 6.0.x cannot migrate to FortiOS 7.x+
    • TLS 1.3 full proxy mode requires 8GB free storage for certificate caching

  2. ​​Known Issues​​:

    • ​​FG-IR-22-411​​: 0.5% packet loss during IPsec phase 2 rekeying with 200+ VPN tunnels
    • ​​FG-IR-22-433​​: HA clusters may require manual synchronization after 150 days uptime

  3. ​​Support Timeline​​:

    • FortiOS 6.0.x reaches end of vulnerability support on March 31, 2024
