Introduction to FGT_60E_DSLJ-v6-build1364-FORTINET.out Software
The FGT_60E_DSLJ-v6-build1364-FORTINET.out firmware delivers FortiOS 6.4.11 for FortiGate 60E DSLJ series appliances, designed for SMB networks requiring integrated xDSL connectivity and enterprise-grade security. Released under Fortinet’s Extended Security Branch (ESB) in Q2 2025, this build resolves 9 critical CVEs while optimizing DSL link stability and VPN performance for remote offices.
Specifically engineered for the 60E DSLJ hardware platform, this firmware combines ADSL2+/VDSL2 modem functionality with unified threat prevention, supporting up to 50 concurrent VPN tunnels. The build (timestamp: 1364) introduces hardware-accelerated traffic shaping for low-bandwidth DSL connections while maintaining backward compatibility with FortiManager 6.4.x configurations.
