Introduction to FGT_3200D-v6-build1364-FORTINET.out Software
This firmware package (FGT_3200D-v6-build1364-FORTINET.out) delivers critical security and performance updates for the FortiGate 3200D hyperscale firewall under FortiOS 6.4.12. Released in May 2025, it resolves 15 CVEs while optimizing operations for carrier-grade and data center environments. The build1364 version enhances NP7 ASIC-driven threat prevention and aligns with NIST SP 800-207 Zero Trust architecture for federal deployments.
Exclusively compatible with FortiGate 3200D models (FG-3200D), this release maintains backward compatibility with FortiOS 6.4.x configurations. Network architects managing multi-terabit infrastructures should prioritize deployment to mitigate critical SSL-VPN vulnerabilities (CVE-2025-21780) and improve 400Gbps traffic engineering efficiency.
Key Features and Improvements
-
Security Enforcement
- Addresses 8 critical CVEs (9.0+ CVSSv3) including CVE-2025-21780 – SSL-VPN heap overflow enabling remote code execution
- Implements quantum-resistant VPN tunnels using NIST-approved CRYSTALS-Kyber algorithms
- FortiGuard threat intelligence updates (v25.7) with 2,800+ new IPS signatures
-
Performance Optimization
- 28% faster IPsec throughput (32 Gbps → 41 Gbps) via NP7 ASIC optimizations
- 50% reduction in memory fragmentation during 400Gbps DDoS mitigation
- Enhanced TCP session setup rate (220,000→265,000 sessions/sec)
-
Protocol Innovation
- Extended TLS 1.3 support with hybrid X448/X25519 key exchange
- Advanced SD-WAN path selection for 400Gbps backbone networks
- IPv6 DHCPv6 Prefix Delegation (RFC 8415) compliance enhancements

Compatibility Notes
- Incompatible with FG-3100D/FG-3300D due to NP7 ASIC architecture differences
- Requires firmware rollback protection disabled for downgrades below 6.4.9
- Full threat prevention requires active FortiGuard Hyperscale Protection subscription
Limitations and Restrictions
-
Functional Constraints
- Maximum 400Gbps throughput requires licensed Security Processing Unit (SPU) acceleration
- Quantum-safe VPN limited to IPsec tunnels (SSL-VPN excluded)
- SD-WAN application steering for 400G interfaces requires separate license
-
Operational Restrictions
- Firmware downgrades below 6.4.9 erase post-quantum cryptography configurations
- Simultaneous SSL inspection/AV scanning limited to 85% of total RAM
- IPv6 DHCPv6 Prefix Delegation requires hardware revision C+
