Introduction to FGT_60E_DSL-v6-build0302-FORTINET.out Software

This firmware package delivers essential security patches and network optimization for FortiGate 60E DSL series next-generation firewalls. Released under FortiOS 6.4.15 in Q1 2025, it addresses 8 documented vulnerabilities while improving DSL broadband throughput by 15% compared to the previous 6.4.14 build. Designed for small-to-medium businesses requiring integrated xDSL connectivity, the update enhances hardware-accelerated threat detection through optimized NP6lite ASIC utilization.

Compatible with FortiGate 60E DSL models featuring VDSL2/ADSL2+ modem interfaces, this build introduces refined WAN failover logic and improved compatibility with FortiManager 7.4 centralized management systems. Network administrators will benefit from 20% faster SSL inspection performance and enhanced VoIP traffic prioritization capabilities.
