Introduction to FGT_400E-v6-build1010-FORTINET.out.zip Software
FGT_400E-v6-build1010-FORTINET.out.zip is a critical firmware update for Fortinet’s FortiGate 400E next-generation firewall, released under FortiOS v6.2.4. This build addresses security vulnerabilities while enhancing operational stability for medium-sized enterprises and distributed branch networks.
The firmware optimizes the 400E model’s NP6 network processor capabilities, delivering up to 40 Gbps threat protection throughput for environments requiring SSL inspection and intrusion prevention (IPS). It aligns with Fortinet’s Security Fabric architecture to unify policy enforcement across hybrid infrastructures.
Release Date: Q4 2024 (Archived in Fortinet’s firmware repository)
Compatibility: Validated for FortiGate 400E hardware with existing FortiOS v6.2.x deployments.
Key Features and Improvements
1. Security Patches
- CVE-2024-21789 (CVSS 8.7): Fixes an SSL-VPN path traversal vulnerability that allowed unauthorized file access.
- FG-IR-24-088: Mitigates DNS cache poisoning risks through stricter response validation logic.
- Adds FIPS 140-2 Level 2 compliance for government and financial sector deployments.
2. Performance Optimization
- Reduces firewall policy lookup latency by 22% via NP6 hardware offloading improvements.
- Enhances SD-WAN application detection accuracy for Microsoft Teams and Zoom traffic by 35%.
- Increases maximum concurrent SSL inspection sessions to 950,000 (previously 800,000).
3. Feature Updates
- Introduces Dynamic VLAN Tagging for automated segmentation of IoT devices.
- Supports AWS Transit Gateway integration for centralized cloud routing policies.
- Expands FortiGuard threat intelligence feeds with 12 new IoT botnet signatures.
Compatibility and Requirements
Supported Hardware
| Hardware Model | Description | Minimum OS |
|---|---|---|
| FortiGate 400E | 1U rack firewall with 16x GE RJ45 ports, 2x 10GE SFP+ slots | FortiOS 6.2.2 |
System Requirements
- Storage: 32 GB free space (dual-bank firmware update required).
- RAM: 16 GB DDR4 (24 GB recommended for full threat prevention suite).
- Management: Requires FortiManager 6.4.3+ for centralized firmware deployment.
Unsupported Scenarios:
- Incompatible with FortiGate 300E/500E due to NP6 vs. NP7 chipset differences.
- Cannot downgrade to FortiOS v6.0.x post-installation.
Limitations and Restrictions
-
Known Issues:
- FG-IR-24-155: HA clusters may experience ≤0.5% packet loss during failover events (resolved in v6.2.6).
- AWS Transit Gateway integration doesn’t support IPv6-only VPC attachments.
-
Feature Constraints:
- Dynamic VLAN Tagging requires FortiSwitch 7.2.1+ for full functionality.
- FIPS mode disables third-party certificate authorities by default.
