Introduction to FGT_94D_POE-v6-build0303-FORTINET.out Software
This critical firmware update addresses multiple high-priority vulnerabilities in FortiGate 94D-POE series next-generation firewalls, designed for enterprise branch offices requiring advanced Power over Ethernet (PoE) capabilities. Released on March 28, 2025, under FortiOS 6.0.18, the build0303 version resolves SSL-VPN security flaws while optimizing network performance for environments deploying IoT devices and wireless access points.
Specifically engineered for the FG-94D-POE hardware platform, this update enhances hardware-accelerated threat prevention through integrated CP8 ASIC chips. It supports compliance frameworks including PCI-DSS 4.0 and HIPAA through improved encrypted traffic analysis capabilities across 24 PoE ports.

Compatibility and Requirements
| Component | Specification |
|---|---|
| Hardware Model | FortiGate 94D-POE (FG-94D-POE) |
| FortiOS Version | 6.0.18 (Build 0303) |
| Minimum RAM | 8GB DDR4 |
| Storage Requirement | 128MB free disk space |
| PoE Standard | IEEE 802.3af/at/bt (24 ports supported) |
This firmware maintains interoperability with FortiSwitch 300-series PoE switches and FortiAP 432F access points. Third-party VoIP systems require SIP v2.0+ protocol support for full feature functionality.
Limitations and Restrictions
- Maximum concurrent IPsec VPN tunnels limited to 500 (hardware capacity)
- No backward compatibility with FortiClient 6.2.x endpoint agents
- Custom web filter profiles require manual migration from v5.6.x configurations
- Firmware rollback to versions prior to 6.0.16 disables PoE+ (802.3bt) support
