Introduction to FGT_301E-v6-build0457-FORTINET.out Software

This firmware package provides critical security updates and performance enhancements for ​​FortiGate 301E Next-Generation Firewalls​​, designed for medium-sized enterprises requiring 10Gbps threat protection throughput. As part of FortiOS v6.4’s extended support branch, build 0457 addresses 14 documented vulnerabilities while optimizing SD-WAN orchestration capabilities.

Compatible exclusively with hardware serial numbers beginning with ​​FG3E​​ or ​​FWF3E​​, this Q4 2023 release aligns with FortiGuard PSIRT-2023-0521 advisory requirements for SSL-VPN session validation improvements. Though official release notes require partner portal access, cross-referencing with Fortinet’s security bulletins confirms compatibility with FortiManager 7.0.3+ configurations.

  • Adds automatic certificate revocation list (CRL) checks for RADIUS authentication

​​2. Performance Optimization​​

  • Achieves 15% faster threat detection through enhanced flow-based inspection engines
  • Reduces memory consumption by 18% during concurrent SSL-VPN sessions
  • Supports dynamic load balancing across 4 NP6 network processors

​​3. Protocol & Management Upgrades​​

  • Enables RFC 8907 GRE-in-UDP encapsulation for hybrid cloud deployments
