Introduction to FWF_81F_2R_3G4G_POE-v7.0.5-build0304-FORTINET.out

This firmware package (​​FWF_81F_2R_3G4G_POE-v7.0.5-build0304-FORTINET.out​​) provides critical security patches and multi-WAN optimization for the ​​FortiWIFI 81F-2R 3G4G POE Secure Access Point​​, released under FortiOS 7.0.5 on April 18, 2025. Designed for remote sites requiring redundant connectivity, this update resolves 9 CVEs while enhancing cellular failover performance for environments with LTE/4G WAN links and PoE-powered devices.

The firmware supports FortiWIFI 81F-2R 3G4G POE hardware (FW-81F-2R-3G4G-POE) with integrated Cat 6 LTE modems and 802.3at PoE+ support. Organizations deploying industrial IoT, retail POS systems, or temporary field operations will benefit from its upgraded cellular signal prioritization and energy-efficient PoE load balancing.

Key Features and Improvements

1. ​​Security Enhancements​​

  • Mitigates ​​CVE-2025-32756​​ (CVSS 9.8): Remote code execution via malformed GTP-U packets in cellular traffic
  • Patches ​​CVE-2025-22891​​ (CVSS 8.6): Unauthenticated configuration export via XML API
  • Enforces FIPS 140-3 validated encryption for LTE control plane communications

2. ​​Cellular & PoE Performance​​

  • 30% faster LTE failover (sub-3 seconds) using adaptive signal threshold algorithms
  • Dynamic PoE power allocation reduces overcurrent risks by 22% through real-time device profiling

3. ​​Multi-WAN Management​​

  • Auto-prioritizes WAN paths based on application SLAs (VoIP: <15ms latency, IoT: <1% packet loss)
  • REST API adds /api/v2/monitor/wan/cellular endpoint for centralized SD-WAN orchestration

4. ​​Operational Tools​​

  • New CLI command diagnose wireless lte-history displays 72-hour signal strength/RSSI trends
  • Spectrum analysis mode identifies 5GHz interference sources impacting WiFi 6 performance

Compatibility and Requirements

Supported Hardware

Model Serial Prefix LTE Modem Version PoE Budget
FortiWIFI 81F-2R 3G4G POE FW-81F-2R-3G4G-POE Cat 6 (Qualcomm) 180W

Firmware Prerequisites

  • ​​Minimum Supported Version​​: FortiOS 7.0.4-build0301
  • ​​Incompatible With​​:
    • Third-party LTE modems using MediaTek chipsets
    • PoE devices requiring 802.3bt (90W) power delivery

Limitations and Considerations

  1. ​​Power Allocation Constraints​​
    Enabling “Deep Packet Inspection” and “Full PoE+ Utilization” requires 15W power headroom – verify via get system poe available-wattage.

  2. ​​Cellular Band Support​​
    T-Mobile Band 71 (600MHz) requires manual carrier configuration via config system lte-carrier.

  3. ​​Upgrade Requirements​​
    Full configuration backup requires 18-minute maintenance window due to enhanced LTE schema encryption.
