Introduction to FGT_300E-v7.0.8.F-build0418-FORTINET.out Software

This firmware package delivers critical network security enhancements for Fortinet’s mid-range enterprise firewall platform. Designed specifically for FortiGate 300E appliances, build 0418 addresses 14 CVSS-rated vulnerabilities while improving threat prevention throughput by 23% compared to v7.0.7 releases.

Validated through 1,800+ hours of carrier-grade testing, the firmware demonstrates 99.96% packet processing stability under 50,000 concurrent VPN tunnels. Compatible with both 300E and 300E-POE hardware configurations, it introduces hardware-accelerated TLS 1.3 decryption capabilities while maintaining backward compatibility with FortiOS 7.0.7 network policies.

Key Features and Improvements

​​Security Architecture Updates​​

  • Mitigates heap overflow vulnerability in IPv4/IPv6 policy enforcement (CVE-2025-3147, CVSS 8.9)
  • Resolves SSL-VPN session fixation vulnerability through enhanced cookie encryption
  • Implements FIPS 140-2 Level 2 compliance for financial sector deployments

​​Performance Optimization​​

  • 8 Gbps TLS inspection throughput using integrated CP9 security processor
  • 17% reduction in firewall policy evaluation latency
  • 600 Mbps IPsec VPN throughput with AES-256-GCM hardware acceleration

​​Operational Enhancements​​

  • Dynamic SD-WAN path selection with application-aware traffic prioritization
  • REST API expansion for bulk security policy management
  • Enhanced FortiView dashboard with real-time threat visualization

Compatibility and Requirements

Supported Hardware Minimum RAM FortiManager Version NPU Accelerator
FortiGate 300E 8GB DDR4 v7.4.3+ required CP9
FortiGate 300E-POE 8GB DDR4 v7.4.3+ required CP9

This build requires Secure Boot verification and shows incompatibility with third-party SFP+ transceivers lacking Fortinet firmware validation. Upgrade from v7.0.6 or later firmware versions is mandatory before installation.

Limitations and Restrictions

  1. ​​Performance Constraints​​
  • Maximum 12 VDOMs supported in default operation mode
  • Hardware acceleration disabled when FIPS-CC mode is active
  1. ​​Compatibility Notes​​
  • Incompatible with FortiAnalyzer versions prior to 7.2.5
  • Requires factory reset when upgrading from v6.4.x firmware
  1. ​​Feature Restrictions​​
  • Maximum 500 IPSec VPN tunnels in FIPS operational mode
  • SSL inspection limited to 5 Gbps with 4K RSA certificates
