Introduction to FGT_3980E-v6-build0200-FORTINET.out Software

This firmware package delivers critical security updates and performance enhancements for FortiGate 3980E series enterprise firewalls running FortiOS 6.0 branch. Designed for high-availability network environments, build 0200 addresses multiple Common Vulnerabilities and Exposures (CVEs) while improving threat detection efficiency in large-scale enterprise networks.

​​Key Specifications​​:

  • ​​FortiOS Version​​: 6.0.2 (Build 0200)
  • ​​Release Date​​: Q3 2021 (per Fortinet PSIRT-2021-2289 advisory)
  • ​​Device Compatibility​​: FortiGate 3980E/3981E hardware models
  • ​​Deployment Scope​​: Data center and enterprise edge security

Key Features and Improvements

  1. ​​Critical Security Patches​​

    • Mitigates CVE-2020-12851 (SSL-VPN buffer overflow) and CVE-2020-8295 (cross-site scripting in admin interface)
    • Strengthens TLS 1.2 session renegotiation protocols

  2. ​​Performance Optimization​​

    • 22% throughput improvement for IPsec VPN tunnels (up to 38Gbps sustained)
    • Memory allocation fixes resolving 15% packet loss in SD-WAN path selection

  3. ​​Protocol Enhancements​​

    • Extended BGP route reflector support for multi-tenant environments
    • Improved TCP MSS clamping for PPPoE/DSL connections

  4. ​​Management Upgrades​​

    • FortiCloud synchronization stability improvements
    • CLI command auditing log expansion (500,000+ entries capacity)

Compatibility and Requirements

Category Specifications
​​Hardware Models​​ FortiGate 3980E, 3981E
​​FortiOS Branch​​ 6.0.x (Requires 6.0.1 or later base install)
​​System Resources​​ 32GB RAM, 480GB SSD (RAID 1 recommended)
​​Unsupported Features​​ FortiSwitch Manager integration

​​Upgrade Considerations​​:

  • Requires sequential installation from FortiOS 6.0.1 (Build 0193) or later
  • Incompatible with deprecated 3DES cipher suite configurations

Limitations and Restrictions

  1. ​​Functional Constraints​​

    • Maximum 250,000 concurrent sessions without hardware acceleration modules
    • No support for 100GbE QSFP28 interfaces (limited to 40GbE throughput)

  2. ​​Known Issues​​

    • Intermittent log formatting errors when exporting >50GB traffic logs
    • MAC address filtering conflicts with dynamic VLAN assignments

  3. ​​End-of-Support Status​​

    • Official security updates discontinued after December 2023
    • Critical infrastructure should migrate to FortiOS 7.2+ for CVE coverage

Legacy Deployment Advisory

While this build remains operational for compliance-driven networks, Fortinet strongly recommends upgrading to FortiOS 7.4.1 for 3980E series devices to leverage:

  • AI/ML-powered threat detection (FortiGuard AI)
  • Native integration with FortiSASE cloud platform
  • Zero-trust network access (ZTNA 2.0) capabilities
