​​Introduction to FGT_301E-v6-build0272-FORTINET.out.zip Software​​

The ​​FGT_301E-v6-build0272-FORTINET.out.zip​​ firmware package delivers critical updates for FortiGate 301E next-generation firewalls running FortiOS 6.0. Designed to enhance network security and operational efficiency, this release addresses vulnerabilities while optimizing firewall throughput and VPN performance.

This build (0272) corresponds to FortiOS 6.0.14 MR3 Patch 2, validated for deployment on FortiGate 301E hardware appliances. First released in Q4 2024, it serves as a maintenance update for organizations requiring extended support for legacy FortiOS 6.0 deployments.
