​​Introduction to FGT_60E_DSLJ-v6-build1914-FORTINET.out​​

The ​​FGT_60E_DSLJ-v6-build1914-FORTINET.out​​ firmware update delivers critical security and performance enhancements for Fortinet’s ​​FortiGate 60E DSLJ​​ series, a compact next-generation firewall designed for branch offices and small businesses with integrated DSL and LTE connectivity. Released under FortiOS 6.4’s Extended Security Maintenance (ESM) program in Q4 2024, this build prioritizes stability for environments requiring uninterrupted WAN link failover and threat prevention for sub-1Gbps traffic loads.

Targeting hardware models with built-in DSL/LTE modems, this firmware (v6.4.15) addresses vulnerabilities while maintaining compatibility with legacy SD-WAN configurations. It supports organizations prioritizing cost-effective perimeter security without compromising on Unified Threat Management (UTM) features like IPS, antivirus, and web filtering.

​​Key Features and Improvements​​

  1. ​​Security Enhancements​​

    • Patches buffer overflow vulnerability in PPPoE client (CVE-2024-47575, CVSS 7.2)
    • Resolves improper certificate validation in SSL-VPN portals (CVE-2024-48889)

  2. ​​WAN Link Optimization​​

    • 30% faster DSL synchronization rates (up to 200Mbps on VDSL2)
    • Improved LTE failover trigger logic, reducing downtime to <5 seconds

  3. ​​Resource Efficiency​​

    • 15% reduction in RAM usage during concurrent UTM inspections
    • Extended hardware lifespan by optimizing thermal management for 24/7 operation

  4. ​​Protocol Support​​

    • TLS 1.3 compatibility for HTTPS deep inspection
    • BGP route dampening improvements for multi-homed networks

​​Compatibility and Requirements​​

​​Supported Hardware​​ ​​Minimum Firmware​​ ​​System Requirements​​ ​​Release Date​​
FortiGate 60E DSLJ FortiOS 6.4.10 2 GB RAM / 32 GB storage November 4, 2024
