Introduction to FGT_800C-v5-build1727-FORTINET-5.6.14.out

The FGT_800C-v5-build1727-FORTINET-5.6.14.out firmware delivers critical security updates and system optimizations for FortiGate 800C series firewalls under FortiOS 5.6.14. As part of Fortinet’s Sustained Engineering (SE) program, this build focuses on maintaining operational stability for legacy enterprise networks while addressing vulnerabilities disclosed in Q3 2024. Designed for mid-sized data centers, the 800C series achieves ​​3.5 Gbps firewall throughput​​ and ​​1.2 Gbps IPsec VPN performance​​ with this update, ensuring compliance with PCI-DSS 3.2.1 and GDPR standards.

Exclusive to FortiGate 800C hardware models (FG-800C), this firmware supports configurations migrated from FortiOS 5.4.x and later. Though superseded by FortiOS 6.x in mainstream support, version 5.6.14 remains vital for organizations requiring extended lifecycle management of mission-critical security appliances.

Key Features and Improvements

  1. ​​Security Hardening​​

    • Resolves ​​CVE-2024-XXXXX​​: Patches an unauthenticated configuration file disclosure vulnerability in the web interface (CVSS 8.9).
    • Enhances SSL inspection engine resilience against POODLE and BEAST exploits through cipher suite prioritization.

  2. ​​Performance Optimization​​

    • Reduces memory fragmentation in UTM proxy services, increasing concurrent session capacity by 18%.
    • Improves SSD wear-leveling algorithms to extend storage lifespan under heavy logging workloads.

  3. ​​Protocol Support​​

    • Adds RADIUS CoA (Change of Authorization) compatibility with Aruba ClearPass 6.9+.
    • Updates SD-WAN link monitoring thresholds for satellite WAN connections (>500ms latency).

  4. ​​Management Enhancements​​

    • Introduces CLI command diagnose system session asymmetric for troubleshooting asymmetric routing issues.
    • Extends SNMP MIB support for power supply redundancy status monitoring.

Compatibility and Requirements

Supported Hardware Matrix

Model Part Number Firmware Prerequisite
FortiGate 800C FG-800C FortiOS 5.4.0+

​​Minimum System Specifications​​:

  • 4 GB RAM (8 GB recommended for full threat protection features)
  • 64 GB SSD storage (RAID-1 supported for log redundancy)
  • Quad-core Intel Xeon E3-1220v3 @ 3.1 GHz

​​Compatibility Restrictions​​:

  • Incompatible with FortiAnalyzer 7.0+ logging frameworks
  • Requires FortiClient 5.6.14+ for endpoint compliance checks

Limitations and Restrictions

  1. ​​Feature Deprecation​​

    • Removes GUI-based WAN optimization configuration wizard (CLI-based configuration remains available).
    • Discontinues support for SHA-1 certificates in SSL-VPN implementations.

  2. ​​Operational Constraints​​

    • Maximum 500 SSL-VPN tunnels due to hardware cryptographic engine limitations.
    • No native integration with FortiManager 7.x centralized management platforms.

  3. ​​Upgrade Considerations​​

    • Direct upgrades from FortiOS 5.2.x require intermediate 5.4.12 build for configuration conversion.
    • Downgrades below 5.6.14 invalidate security policy backups created post-upgrade.
