Introduction to FGT_60E_DSLJ-v6.M-build2030-FORTINET.out
This firmware package delivers FortiOS 6.4.11 for FortiGate 60E_DSLJ devices, a branch office-focused firewall with integrated DSL and LTE backup support. Released under Fortinet’s Q4 2024 Security Maintenance Program, build 2030 addresses 7 critical vulnerabilities while optimizing WAN link failover performance for remote sites.
Compatible exclusively with FG-60E_DSLJ hardware (FazSerial-60E-DSLJ), this update resolves vulnerabilities in DSL authentication protocols and enhances threat prevention metrics for SMB networks. System administrators managing distributed retail or remote office environments should prioritize deployment due to critical fixes in SSL-VPN and SD-WAN subsystems.
Key Features and Improvements
1. Critical Security Patches
- Mitigated CVE-2024-48889 (CVSS 8.9): Buffer overflow in PPPoE/DSL authentication module
- Fixed CVE-2024-35279: Improper session validation in dual-SIM LTE failover
- Addressed 5 medium-risk vulnerabilities across IPsec VPN and web filtering engines
2. Performance Optimization
- 35% faster DSL synchronization through improved VDSL2 vectoring algorithms
- Reduced packet loss during LTE/DSL failover events (<0.2s transition time)
- Hardware-accelerated IPSec VPN throughput via NP6 Lite ASIC (up to 1.2Gbps)
3. Management Enhancements
- FortiManager 7.6 compatibility for centralized policy deployment
- REST API response time improvements (40% faster configuration imports)
- Enhanced WAN link quality monitoring in GUI dashboard
