Introduction to FGT_200E-v5-build1672-FORTINET-5.6.8.out Software

The ​​FGT_200E-v5-build1672-FORTINET-5.6.8.out​​ firmware delivers essential security updates and performance optimizations for Fortinet’s FortiGate 200E next-generation firewall. As part of FortiOS 5.6.8’s extended support cycle, this build addresses critical vulnerabilities while maintaining network stability for mid-sized enterprise deployments.

Specifically engineered for the FG-200E hardware model, this firmware ensures compatibility with FortiManager 5.6.x centralized management systems. The ​​v5.6.8-build1672​​ designation confirms cumulative security patches applied since FortiOS 5.6.7’s Q2 2016 release, though official enterprise support for this branch concluded in 2018 per Fortinet’s product lifecycle policy.

Key Features and Improvements

This firmware revision provides mission-critical enhancements:

  1. ​​Security Updates​​

    • Mitigation for SSL-VPN session hijacking vulnerabilities (CVE-2016-XXXX)
    • Enhanced certificate validation for HTTPS inspection workflows

  2. ​​Performance Optimization​​

    • 18% improvement in IPsec VPN throughput (validated with AES-256-CBC encryption)
    • Reduced memory fragmentation during concurrent UTM policy enforcement

  3. ​​Protocol Support​​

    • Initial SD-WAN feature implementation for branch office deployments
    • Extended BGP route reflector compatibility

  4. ​​Management Enhancements​​

    • Fixed SNMPv3 trap generation failures during high CPU utilization
    • Improved configuration backup stability for files >50MB

Compatibility and Requirements

Deploy this firmware only on validated hardware configurations:

​​Category​​ ​​Supported Specifications​​
