Introduction to FGT_60E_DSL-v6-build1343-FORTINET.out Software
This firmware package (FGT_60E_DSL-v6-build1343-FORTINET.out) delivers critical updates for FortiGate 60E DSL models under FortiOS 6.4.12. Released in April 2025, it addresses 9 CVEs while optimizing broadband network operations for small-to-medium branch offices. The build1343 version specifically enhances xDSL modem stability and aligns with NIST SP 800-207 Zero Trust requirements for distributed networks.
Exclusively compatible with FortiGate 60E DSL (FG-60E-DSL) hardware, this release maintains backward compatibility with FortiOS 6.4.x configurations. Network administrators managing remote sites should prioritize deployment to mitigate critical PPPoE vulnerabilities (CVE-2025-21772) and improve VDSL2 synchronization performance.
Key Features and Improvements

Compatibility Notes
- Incompatible with non-DSL FG-60E models due to modem hardware differences
- Requires firmware rollback protection disabled for downgrades below 6.4.9
- Full threat prevention requires active FortiGuard Unified Protection subscription
Limitations and Restrictions
-
Functional Constraints
