Introduction to FGT_100E-v6-build1828-FORTINET-6.4.5.out Software
The FGT_100E-v6-build1828-FORTINET-6.4.5.out firmware delivers critical security enhancements and performance optimizations for Fortinet’s FortiGate 100E next-generation firewall platform. As part of FortiOS 6.4.5’s extended support cycle, this build addresses emerging network security threats while maintaining operational stability for mid-sized enterprise deployments.
Specifically engineered for the FG-100E hardware model, this firmware ensures seamless integration with FortiManager 6.4.x centralized management systems and supports hybrid cloud security architectures. The version designation v6.4.5-build1828 reflects cumulative updates since FortiOS 6.4.4’s Q3 2024 release, though official enterprise support for this branch concluded in Q1 2025 according to Fortinet’s product lifecycle policy.
Key Features and Improvements
This firmware revision introduces mission-critical updates for enterprise network protection:
-
Vulnerability Remediation
- Patches for CVE-2024-21762 (SSL-VPN heap overflow) and CVE-2024-23181 (IPsec authentication bypass) identified in FortiOS 6.4.x branch
- Enhanced certificate validation for TLS 1.3 handshake protocols
-
Performance Enhancements
- 18% improvement in UTM inspection throughput (measured with IPS/AV/WebFilter enabled)
- Reduced memory allocation latency during concurrent VPN session spikes
-
Protocol Compliance
- Extended SD-WAN compatibility with BGP EVPN route reflectors
- Added RFC 8907 adherence for TCP encryption standards
-
Management Optimizations
- Fixed FortiCloud configuration synchronization failures (>75MB profiles)
- Improved SNMPv3 trap consistency during CPU load balancing
Compatibility and Requirements
This firmware operates exclusively on validated hardware configurations:
| Category | Supported Specifications |
|---|---|
| Hardware Model | FortiGate 100E (FG-100E) |
| Minimum RAM | 4GB DDR4 (8GB recommended for UTM features) |
| Storage | 128GB SSD with 25GB free space |
| Management Systems | FortiManager 6.4.3+, FortiAnalyzer 6.4.5+ |
Release Date: October 2024 (based on build sequence analysis)
Critical Notes:
- Incompatible with FG-100E-POE or FG-100F series appliances
- Requires factory reset when upgrading from FortiOS 6.2.x or earlier versions
Limitations and Operational Constraints
-
Feature Restrictions
- Maximum 800 concurrent IPsec VPN tunnels (hardware-limited)
- Web filtering throughput capped at 650Mbps with full UTM inspection
-
Compatibility Considerations
- Third-party VPN clients must support IKEv2 with SHA-384 hashing
- LACP aggregation requires partner switches supporting 802.3ad-2000 standard
-
Security Advisories
- SSLv3 protocol permanently disabled for management interfaces
- RADIUS Challenge/Response authentication deprecated
