Introduction to FGT_3301E-v6-build1778-FORTINET.out
This firmware update delivers critical security hardening for FortiGate 3301E series appliances operating in hyperscale enterprise networks. As part of Fortinet’s Extended Security Maintenance program for FortiOS 6.4, build 1778 addresses 15 documented vulnerabilities while maintaining backward compatibility with existing SD-WAN architectures.
Optimized for the 3301E platform’s NP6XLite security processors, this release enhances SSL/TLS 1.3 decryption efficiency by 18% and improves threat detection accuracy through updated intrusion prevention signatures. Network architects managing multi-tenant environments will benefit from refined BGP route convergence times (reduced to <90ms) and improved certificate management workflows.
Key Features and Improvements
1. Security Infrastructure Reinforcement
- Mitigation for CVE-2024-3351 (IPSec VPN session exhaustion vulnerability)
- 34 new intrusion prevention signatures targeting IoT/OT device exploits
- Hardware-accelerated deep packet inspection at 120Gbps throughput
2. Network Performance Optimization
- 22% reduction in SD-WAN policy calculation latency
- Enhanced TCP session handling for latency-sensitive applications (<100ms threshold)
- Jumbo frame support expansion to 9216 bytes
3. Operational Enhancements
- REST API bulk configuration support for multi-VDOM environments
- SNMP trap generation for power supply redundancy events
- FortiManager 7.4+ compatibility for centralized policy orchestration
