Introduction to FGT_301E-v6-build0231-FORTINET.out.zip

This firmware update delivers FortiOS 6.4.15 for FortiGate 301E series next-generation firewalls, addressing 19 critical vulnerabilities while optimizing enterprise edge network performance. Released on February 28, 2025 (build 0231), the package targets hardware platforms including FortiGate 301E/301EF/301E-3G4G models, designed for high-availability security operations in distributed corporate environments.

The update maintains backward compatibility with FortiOS 6.4.x configurations while requiring NP6XT security processors for full threat prevention capabilities. It resolves critical CVEs identified in Q4 2024 security bulletins and introduces enhanced TLS 1.3 traffic inspection through hardware acceleration.

Compatibility Matrix

Supported Hardware Minimum RAM Storage Requirement NPU Version
FortiGate 301E 64GB DDR4 1TB NVMe SSD NP6XT
FortiGate 301EF 128GB DDR4 2TB RAID SSD NP6XL
FortiGate 301E-3G4G 64GB DDR4 1TB eMMC Storage NP6Lite

This build maintains interoperability with FortiSwitch 448E and FortiAP 841F devices running FortiLink OS 5.0.4+. Dual-stack network configurations require policy revalidation when upgrading from builds prior to 0220.

Limitations & Restrictions

  1. Maximum 8,192 concurrent SSL-VPN users per chassis cluster configuration
  2. Hardware-accelerated deep packet inspection limited to first 16 NP6XT cores
  3. Requires FortiAnalyzer 7.6.1+ for log correlation features
  4. Custom certificate chains exceeding 8KB require post-upgrade reconfiguration
