Introduction to FGT_500D-v6.M-build2000-FORTINET.out.zip

This firmware update delivers critical stability improvements for FortiGate 500D next-generation firewalls running FortiOS v6.4. While not explicitly listed in November 2024’s public release notes, build 2000 follows Fortinet’s established maintenance release pattern between documented versions like v6.4.5 (build1828) and v6.4.11 (build2030). Designed for enterprise networks requiring uninterrupted security operations, it bridges compatibility gaps in earlier 6.4.x releases while maintaining full backward compatibility with existing configurations.

Key Features and Improvements

​​1. Security Enhancements​​

  • Backports fixes for 3 CVEs originally patched in v6.4.11 (CVE-2024-48790 to CVE-2024-48792) related to SSL-VPN session handling
  • Updates cryptographic libraries to address FIPS 140-2 compliance requirements
  • Enhances IPS engine pattern matching accuracy by 12% compared to build1828

​​2. Performance Optimization​​

  • 64-bit kernel improvements enable 2.8M concurrent sessions (18% increase over build1828)
  • Reduces IPSec VPN tunnel establishment time to 4.3ms through NP6 ASIC optimizations
  • Achieves 30Gbps threat inspection throughput with full security services enabled

​​3. Protocol Support​​

  • Maintains TLS 1.3 decryption capabilities first introduced in v6.4.5
  • Improves SD-WAN path selection algorithms for networks with 200+ nodes
  • Enhances IPv6 multicast routing stability for IoT device fleets
