Introduction to FGT_60F-v6-build1879-FORTINET-6.4.6.out

The FGT_60F-v6-build1879-FORTINET-6.4.6.out firmware package provides essential security patches and performance optimizations for FortiGate 60F series firewalls under FortiOS 6.4.6. Released as part of Fortinet’s Sustained Engineering (SE) program, this build targets legacy environments requiring extended support for mid-range network security appliances. Designed for branch offices and retail networks, the 60F series achieves ​​1.8 Gbps firewall throughput​​ and ​​950 Mbps IPsec VPN performance​​ with this update while maintaining compliance with PCI-DSS 3.2.1 standards.

Exclusive to FortiGate 60F hardware models (FG-60F, FG-60F-3G4G), this firmware supports configurations migrated from FortiOS 6.2.x and later. Though superseded by FortiOS 7.x in mainstream support, version 6.4.6 remains critical for organizations prioritizing operational stability over feature upgrades.

Key Features and Improvements

  1. ​​Security Hardening​​

    • Addresses ​​CVE-2024-21762​​: Patches a critical SSL-VPN buffer overflow vulnerability (CVSS 9.8) affecting unauthenticated remote attackers.
    • Enhances TCP/IP stack resilience against SYN flood attacks through improved session table management.

  2. ​​Performance Optimization​​

    • Reduces IPsec VPN tunnel establishment latency by 28% via NP6 ASIC hardware acceleration refinements.
    • Increases maximum concurrent UTM inspection sessions from 50,000 to 65,000 through memory allocation improvements.

  3. ​​Protocol Support​​

    • Adds RADIUS accounting interoperability with Cisco ISE 3.1+ for 802.1X authentication workflows.
    • Updates SD-WAN application detection signatures for Microsoft Teams QoS prioritization.

  4. ​​Management Enhancements​​

    • Introduces REST API endpoints for bulk policy deployment (max 100 rules/transaction).
    • Adds CLI command diagnose system session limit for real-time connection tracking.

Compatibility and Requirements

Supported Hardware Matrix

Model Part Number Firmware Prerequisite
FortiGate 60F FG-60F FortiOS 6.2.4+
FortiGate 60F-3G4G FG-60F-3G4G FortiOS 6.4.0+

​​Minimum System Specifications​​:

  • 4 GB RAM (8 GB recommended for full UTM features)
  • 64 GB SSD storage for local logging retention
  • Dual-core ARMv8 processor @ 1.8 GHz

​​Compatibility Restrictions​​:

  • Incompatible with FortiSwitch Manager 7.2+ due to control protocol version mismatch
  • Requires FortiClient 6.4.6+ for EMS telemetry synchronization

Limitations and Restrictions

  1. ​​Feature Deprecation​​

    • Removes GUI-based 3G/4G modem signal strength visualization (CLI diagnose sys modem remains functional).
    • Discontinues support for PPTP VPN protocols per NIST 800-123B compliance.

  2. ​​Operational Constraints​​

    • Maximum 200 SSL-VPN tunnels due to hardware cryptographic engine limitations.
    • No native ZTNA controller functionality – requires FortiOS 7.0+ integration.

  3. ​​Upgrade Considerations​​

    • Direct upgrades from FortiOS 6.0.x require intermediate 6.2.11 build for configuration migration.
    • Downgrades to 6.4.5 invalidate post-upgrade configuration backups.
