Introduction to FGT_3400E-v6.M-build2000-FORTINET.out
This firmware package delivers mission-critical updates for FortiGate 3400E, an enterprise-grade next-generation firewall designed for hyperscale data centers and carrier networks requiring 400Gbps+ threat inspection throughput. As part of FortiOS 6.4.15’s extended support cycle, build 2000 addresses 28 security advisories while optimizing the NP7 network processor’s deep packet inspection capabilities. Exclusively compatible with FortiGate 3400E hardware (FG-3400E), this Q2 2025 release aligns with Fortinet’s quarterly security update cadence for critical infrastructure environments.
Key Features and Improvements

- Adds experimental QUIC protocol inspection capabilities for cloud-native applications
-
Management Upgrades
- FortiManager integration now supports 10,000-device configuration templates
- REST API v3.1 introduces granular control over hyperscale VDOM configurations
Compatibility and Requirements
| Category | Specifications |
|---|---|
| Hardware Model | FortiGate 3400E (FG-3400E) exclusively |
| FortiOS Baseline | Requires v6.4.12 or newer |
| NP7 Processor | Revision E with 400G ASIC |
| Storage | 1TB NVMe SSD (minimum 300GB free space) |
| Memory | 256GB DDR5 (240GB allocated for security services) |
⚠️ Critical Notes:
- Incompatible with FG-3200E/3600E series due to chassis architecture differences
- Requires full configuration export before downgrading to v6.2.x firmware
Limitations and Restrictions
-
Functional Constraints
- Hardware-accelerated SRv6 limited to 200Gbps throughput on 400G interfaces
- Maximum 32-node HA clusters supported vs. 64-node capacity in FG-3800F+ models
-
Licensing Requirements
- Hyperscale VDOM features require active FortiCare Enterprise License
- Cloud-native security services mandate separate FortiCASB subscription
