Introduction to FGT_201E-v6.M-build2095-FORTINET.out Software
The FGT_201E-v6.M-build2095-FORTINET.out firmware package delivers FortiOS 6.4.15 for FortiGate 200E series next-generation firewalls, addressing critical vulnerabilities while enhancing enterprise network security capabilities. Released in Q4 2024, this maintenance update resolves 12 documented CVEs and introduces performance optimizations for encrypted traffic inspection.
Designed specifically for the FortiGate 201E hardware platform, this build supports dual-stack IPv4/IPv6 environments and integrates with Fortinet Security Fabric components like FortiAnalyzer and FortiManager. The “M” suffix denotes enhanced memory management algorithms proven to reduce packet processing latency by 18% in lab tests compared to previous 6.4.x releases.

Compatibility and Requirements
| Category | Specifications |
|---|---|
| Supported Hardware | FortiGate 201E, 201E-POE, 201E-3G4G |
| Minimum RAM | 8 GB DDR4 |
| Storage | 64 GB SSD (dual-bank firmware support) |
| FortiManager | 7.4.3 or later |
| FortiAnalyzer | 7.2.1 or later |
| Upgrade Path | 6.4.11 → 6.4.15 (direct update supported) |
This release maintains backward compatibility with FortiOS 6.4.11 configurations but requires firmware reactivation when downgrading to versions below 6.4.13. Administrators must verify sufficient storage space (minimum 12GB free) before installation.
Limitations and Restrictions
- Hardware Constraints
- Does not support 40G QSFP+ interfaces on 201E-3G4G variant
- HA cluster requires identical BIOS versions across nodes
- Feature Limitations
- SD-WAN application steering requires separate FortiCare contract
- Maximum 500 concurrent SSL-VPN users (upgradable via license)
- Known Issues
- Interface statistics mismatch during HA failover (documented in FN-10562)
- Temporary log formatting errors when integrating with FortiAnalyzer 7.0.x
