Introduction to FGT_60E_DSL-v7.2.6.F-build1575-FORTINET.out

This firmware release (build 1575) delivers critical security updates and DSL performance enhancements for FortiGate 60E-DSL unified threat management appliances, designed for small-to-medium businesses requiring integrated xDSL connectivity. As part of FortiOS 7.2.6.F’s security architecture, it resolves 9 CVEs identified in SSL-VPN and intrusion prevention components while introducing VDSL2 vectoring improvements.

Exclusively compatible with FortiGate 60E-DSL hardware (FG-60E-DSL), this Q3 2025 release achieves FIPS 140-3 Level 2 compliance and supports automated DSL line diagnostics through FortiManager integration. Network administrators managing branch offices will benefit from its enhanced PPPoE session stability and temperature-regulated DSL signal modulation.
