1. Introduction to FGT_3000D-v6-build0200-FORTINET.out Software
The FGT_3000D-v6-build0200-FORTINET.out firmware delivers critical security hardening and stability improvements for Fortinet’s enterprise-grade FortiGate 3000D firewall platform. Designed for high-availability networks, this legacy build addresses vulnerabilities disclosed in FortiOS 6.0.x while maintaining compatibility with older network architectures.
Compatibility & Release Context
- Supported Hardware: FortiGate 3000D (FG-3000D) chassis exclusively
- FortiOS Version: v6.0 branch (End-of-Support since Q3 2024)
- Release Timeline: Q2 2023 (per Fortinet PSIRT FG-IR-23-115)
This update serves enterprises requiring interim vulnerability mitigation before migrating to supported FortiOS 7.4.x deployments.
2. Key Features and Security Improvements
Vulnerability Remediation
- CVE-2023-27997: Patched heap overflow in X.509 certificate parsing (CVSS 8.7)
- CVE-2023-25610: Fixed improper session validation in SSL-VPN portals
- FortiGuard Updates: Integrated IPS signature database v20.1+ to counter Cactus ransomware variants
Operational Enhancements
- Reduced memory leaks during BGP route processing (>500k routing table entries)
- Improved SSD wear-leveling for FG-3000D’s RAID-1 storage configuration
- 18% faster IPsec throughput (up to 95 Gbps) with NP6 processor optimizations
Protocol Compliance
- Extended VXLAN support for multi-tenant cloud environments
- Fixed OSPFv3 packet handling in IPv6-only network topologies
3. Compatibility and System Requirements
| Category | Specifications |
|---|---|
| Hardware Model | FortiGate 3000D (FG-3000D) |
| Minimum RAM | 64 GB DDR4 (128 GB recommended) |
| Storage | Dual 960 GB SSD (RAID-1) |
| Management Interfaces | GUI/CLI, FortiManager 6.4+ |
Critical Notes:
- Incompatible with FG-3000E/F models due to NP7 ASIC architecture changes
- Requires chassis reboot when downgrading from v6.2.15+ firmware
4. Limitations and Restrictions
End-of-Support Considerations
- No CVE-2024-23110 Fix: Lacks patches for critical FortiOS SSL-VPN exploits
- Deprecated Features: Excludes ZTNA 2.0 and SD-WAN Orchestrator capabilities
- Maximum Throughput: Limited to 120 Gbps vs. 210 Gbps in FortiOS 7.x
Operational Constraints
- No support for TLS 1.3 or post-quantum cryptography algorithms
- Maximum concurrent VPN users: 10,000 (vs. 25,000 in v7.4.x)
5. Verified Software Acquisition

Final Recommendations
Fortinet discontinued security updates for v6.0 in September 2024. While FGT_3000D-v6-build0200-FORTINET.out addresses legacy vulnerabilities, prioritize migration to FortiOS 7.4.6 for:
- AI-driven threat intelligence updates
- 400Gbps+ throughput with NP7XLite acceleration
- Quantum-safe VPN encryption support
