Introduction to FGT_60E_DSLJ-v6-build6164-FORTINET.out

This firmware package delivers critical security hardening and DSL broadband optimization for FortiGate 60E DSLJ appliances running FortiOS 6.x. Designed for branch offices requiring integrated xDSL connectivity, build 6164 resolves vulnerabilities affecting PPPoE negotiation stability while improving intrusion prevention system (IPS) throughput by 19% in lab-tested scenarios.

The software explicitly supports FortiGate 60E DSLJ hardware (FG-60E-DSLJ) with embedded VDSL2/ADSL2+ modems. Though no official release date is published, Fortinet’s build numbering convention indicates this version aligns with Q2 2025 security maintenance cycles. It requires FortiOS 6.4.12 as a baseline for installation.
