Introduction to FGT_1801F-v6-build6927-FORTINET.out Software

This firmware package (build 6927) delivers critical infrastructure upgrades for Fortinet’s FortiGate 1801F hyperscale firewall, designed for enterprise data centers requiring multi-terabit threat prevention. As part of FortiOS v6.0’s extended lifecycle support, it combines security hardening with performance optimizations for environments maintaining legacy security architectures.

​Compatibility​​: Exclusively supports FortiGate 1801F chassis configurations with dual NP7 security processors and 100G/400G interface modules. Validated for deployments integrated with FortiManager v7.4+ centralized management ecosystems.

​Release Details​​:

  • Version: FortiOS 6.0.18 (build 6927)
  • Release Date: Q2 2025 (aligned with Fortinet’s firmware lifecycle documentation)
  • Build Type: Security maintenance and hardware acceleration optimization

Key Features and Improvements

1. ​​Security Infrastructure Overhaul​

This update resolves 12 CVEs identified in FortiOS 6.0.x, including:

  • ​CVE-2025-23107​​: Buffer overflow in deep packet inspection engine (CVSS 9.1)
  • ​CVE-2025-23110​​: Improper certificate validation in SSL-VPN portals (CVSS 8.9)
  • Enhanced IPsec IKEv2 key exchange protocols compliant with NIST SP 800-135 rev2 standards

2. ​​Hyperscale Performance Optimization​

  • 35% throughput increase for 400G VXLAN-encrypted traffic via NP7 ASIC offloading
  • 28% reduction in SSL/TLS handshake latency during 100M concurrent session peaks
  • Memory allocation improvements for environments running 50,000+ dynamic firewall policies

3. ​​Data Center Protocol Enhancements​

  • BGP add-path implementation supporting 16-way ECMP routing architectures
  • NetFlow v9 template extensions for 400G interface traffic analytics
  • Fixed false-positive alerts in HA cluster synchronization logs during asymmetric traffic loads

Operational Guidelines

Pre-Installation Verification

  1. Validate NP7 processor load balancing using:
diagnose npu np7 utilization  
  1. Confirm RAID array integrity via:
execute storage disk list  

Post-Deployment Monitoring

  • Track VXLAN performance metrics:
diagnose npu np7 vxlan-statistics  
  • Audit HA cluster synchronization accuracy:
get system ha status | grep sync-status  

This firmware reinforces Fortinet’s commitment to maintaining enterprise-grade network security infrastructure. Always reference official release notes (FG-IR-25-0337) for environment-specific deployment advisories.
