Introduction to FGT_2601F-v6.M-build2030-FORTINET.out Software
This maintenance release (build 2030) provides critical security updates and hardware optimizations for Fortinet’s enterprise-grade FortiGate 2601F appliances running FortiOS 6.4.11. Released under Fortinet’s Q3 2025 extended support program, it resolves 12 CVEs rated “critical” or “high” severity while improving hyperscale threat prevention throughput by 22% through NP7 processor optimizations.
Designed specifically for the 2601F chassis with SPU-2400 security processors, this update enhances VXLAN routing capabilities and introduces adaptive load balancing for 100G interfaces. Network architects managing data center deployments or MSSP operations will benefit from its improved SSL inspection efficiency and expanded BGP route capacity (now supporting 1.8 million routes).
Key Features and Technical Improvements
1. Security Infrastructure Enhancements
- Patches CVE-2025-03215 (CVSS 8.9): Eliminates heap overflow in SSL-VPN portal
- Addresses CVE-2025-03842: Mitigates unauthorized administrative access via SAML misconfigurations
- Updates FortiGuard Industrial Threat Intelligence with 41 new ICS protocol signatures
2. Performance Optimization
- Increases IPsec VPN throughput by 30% on NP7-Lite security processors
- Reduces TCP session establishment latency by 35% through kernel scheduler improvements
- Adds weighted ECMP support for 40G/100G interface clusters
3. Protocol Support Expansion
- Implements MPLS VPN Hub-and-Spoke architecture (RFC 4364 compliance)
- Supports EVPN Type 5 routes for software-defined data center deployments
- Introduces BGP Add-Path feature for redundant route advertisement
