Introduction to FGT_80CM-v5-build1714-FORTINET-5.6.13.out

This firmware release delivers critical security patches and operational stability improvements for FortiGate 80CM series firewalls running FortiOS 5.6.13. Designed as a maintenance update for enterprise branch offices, it resolves 9 documented vulnerabilities while maintaining backward compatibility with legacy network configurations.

Specifically optimized for FGT-80CM hardware platforms, build 1714 supports organizations requiring 2Gbps firewall throughput with SSL inspection capabilities. Originally released in Q1 2018, this version represents the final security-focused update before FortiOS 6.0 branch migration.

Key Features and Improvements

​​Security Enhancements​​

  • Critical mitigation for CVE-2017-17558 (HTTP header injection vulnerability)
  • Enhanced IPS engine with 42 updated threat detection signatures

​​Performance Optimizations​​

  • 18% reduction in memory consumption during concurrent VPN sessions
  • Improved NP4 ASIC utilization for SPI traffic inspection

​​Protocol Support​​

  • Extended PPPoE stability for xDSL modem interfaces
  • Fixed L2TP/IPSec tunnel negotiation failures

​​Management Upgrades​​

  • CLI command stability improvements for policy batch operations
  • Resolved GUI display errors in traffic shaping monitors

Compatibility and Requirements

Component Supported Specifications
Hardware Models FortiGate 80CM, 80CM-DSL, 80CM-WIFI
Minimum RAM 4GB DDR3 (non-expandable)
Storage 32GB HDD (RAID not supported)
Uplink Interfaces 8x GE RJ45 ports (2x xDSL on 80CM-DSL)

This firmware maintains configuration compatibility with FortiOS 5.6.12 but requires manual certificate renewal when upgrading from 5.4.x releases. Third-party antivirus solutions must use pattern files dated prior to Q4 2017 for full integration.

Limitations and Restrictions

  1. Maximum concurrent SSL-VPN users capped at 100 (vs. 200 in 6.x versions)
  2. Web filtering limited to 64 category classifications
  3. Does not support SHA-3 cryptographic algorithms
  4. Factory reset required when downgrading from 6.0+ firmware
