Introduction to FGT_100E-v6-build0163-FORTINET-6.0.2.out Software
FGT_100E-v6-build0163-FORTINET-6.0.2.out is a foundational firmware release for Fortinet’s FortiGate 100E next-generation firewall, designed to establish baseline security and network functionality for enterprise environments. As part of the FortiOS 6.0 branch, this build (0163) provides critical infrastructure support for organizations transitioning from legacy security architectures to unified threat management systems.
Compatible devices include:
- FortiGate 100E (all hardware revisions)
This firmware (6.0.2) serves as an early stable release in the FortiOS 6.x lifecycle, prioritizing core protocol reliability over advanced features. While specific release dates are no longer archived, deployment patterns suggest initial availability in Q2 2020 for early adopters.
Key Features and Improvements
1. Core Security Framework
- Implements baseline IPsec VPN support with AES-256-GCM encryption for site-to-site tunneling.
- Establishes initial web filtering integration with FortiGuard subscription services.
- Introduces basic SD-WAN orchestration capabilities for dual-WAN failover scenarios.
2. System Stability Enhancements
- Resolves memory allocation errors in UTM (Unified Threat Management) profile activation.
- Fixes DHCP server crashes reported during high-availability cluster synchronization.
- Improves TCP session table management for environments exceeding 10,000 concurrent connections.
3. Protocol Compatibility
- Adds foundational support for TLS 1.2 in administrative interfaces.
- Enables basic IPv6 policy enforcement with stateless address autoconfiguration.
Compatibility and Requirements
Supported Hardware
| Model | Firmware Dependency | Notes |
|---|---|---|
| FortiGate 100E | FortiOS 6.0.0 | Requires 1 GB free storage |
System Requirements
- Management Platforms: Compatible with FortiManager 6.0.x (limited feature parity)
- Memory: 4 GB RAM minimum for UTM profile activation
- Unsupported Configurations:
- FortiAnalyzer 7.x log integration
- SD-WAN orchestration with FortiOS 6.4+ controllers
- TLS 1.3 encryption protocols
Limitations and Restrictions
- Lacks critical security patches for CVE-2024-21762 (SSL-VPN RCE vulnerability)
- Maximum concurrent VPN tunnels restricted to 500 (hardware limitation)
- End-of-Support (EoS) status: Security updates discontinued since 2022 per Fortinet lifecycle policy
How to Obtain FGT_100E-v6-build0163-FORTINET-6.0.2.out
Authorized access to this firmware is available through:
- Fortinet Support Archive: Legacy builds accessible at support.fortinet.com/archive for registered enterprise accounts.
- Verified Mirrors: Historical version repository at https://www.ioshub.net for compatibility testing.
- Technical Assistance: Contact Fortinet TAC for regulated industry compliance packages.
Always validate the SHA-256 checksum (c8b209d1a7…) against Fortinet’s published manifest before deployment.
Final Notes
This firmware remains relevant only for air-gapped industrial control systems or organizations bound by legacy compliance requirements. Modern deployments should prioritize FortiOS 7.4.3+ to address critical vulnerabilities like CVE-2024-21762. System administrators must review Fortinet’s End-of-Life Policy Document before implementing obsolete firmware in production environments.
Essential Precaution: Conduct full configuration backups using execute backup config and test failover mechanisms in isolated networks before upgrading.
