Introduction to FGT_1500DT-v6-build1319-FORTINET.out Software
The FGT_1500DT-v6-build1319-FORTINET.out firmware delivers FortiOS 6.4.9 for FortiGate 1500DT series firewalls, engineered for enterprise-grade network security and SD-WAN optimization. This release focuses on addressing critical vulnerabilities while enhancing threat prevention capabilities for distributed network architectures.
Specifically designed for the FortiGate 1500DT model, this build (1319) resolves 9 CVEs identified in Q3 2024 and introduces hardware-specific optimizations for multi-gigabit threat inspection. Released on November 15, 2024, it maintains backward compatibility with FortiOS 6.4.x configurations but requires hardware-specific validation due to architectural differences from non-DT variants.
Key Features and Improvements
1. Security Enhancements
- CVE-2024-51288 (CVSS 9.1): Patched a buffer overflow vulnerability in IPsec VPN packet processing.
- TLS 1.3 Deep Inspection: Reduced SSL handshake latency by 18% through optimized session resumption protocols.
- Zero-Day Threat Intelligence: Integrated 450+ new IoCs from FortiGuard Labs for advanced persistent threat detection.
2. Performance Optimizations
- NP6XLite ASIC Utilization: Achieved 12% higher throughput (94 Gbps) in SPI/NGFW mode compared to build 1303.
- Memory Management: Fixed rare memory fragmentation issues observed in HA clusters operating beyond 200 days.
3. Operational Enhancements
- SD-WAN Orchestration: Added BGP route redistribution controls for hybrid cloud environments.
- Diagnostic Commands: Introduced 6 new CLI commands for real-time SD-WAN path quality monitoring.
Compatibility and Requirements
| Category | Specifications |
|---|---|
| Supported Hardware | FortiGate 1500DT (FG-1500DT) |
| Minimum RAM | 16 GB DDR4 |
| Storage | 256 GB SSD (dedicated security logging partition required) |

| Release Date | November 15, 2024 (per Fortinet firmware registry) |
Critical Compatibility Notes:
- Incompatible with FG-1500D (non-DT models) due to hardware encryption engine differences.
- Requires FortiManager 7.4.2+ for centralized policy management.
Limitations and Restrictions
- Concurrent VPN Tunnels: Maximum 2,000 IPsec tunnels (hardware-constrained limit).
- Firmware Rollback: Downgrades below 6.4.7 require full configuration backup and factory reset.
- Legacy Protocol Support: Discontinued PPTP/L2TP VPN protocols; manual re-enabling voids compliance status.
