​​Introduction to FGT_60E_DSL-v6-build0505-FORTINET.out​​

This firmware update targets Fortinet’s ​​FortiGate 60E DSL Series​​ security appliances, specifically designed for branch offices requiring integrated DSL connectivity and enterprise-grade threat protection. As part of FortiOS 6.4.x maintenance releases, build 0505 focuses on resolving critical vulnerabilities while maintaining operational stability for small-to-medium business networks.

The firmware is validated for ​​FortiGate 60E DSL​​ hardware models running FortiOS 6.4.5 or later, with backward compatibility for configurations deployed in FortiOS 6.4.x environments. While Fortinet’s official release notes don’t explicitly list build 0505’s publication date, the build numbering convention suggests a Q4 2024 release cycle.
