Introduction to FGT_1800F-v7.2.5.F-build1517-FORTINET.out Software
This firmware release (v7.2.5.F-build1517) delivers enterprise-grade security enhancements and network optimization for FortiGate 1800F series next-generation firewalls. Officially released in May 2025 as part of Fortinet’s quarterly security update cycle, it addresses 9 CVEs while introducing hardware-specific performance improvements for hyperscale data center deployments.
Designed exclusively for FortiGate 1800F and 1800F-2R hardware models, this version enhances 400G interface stability and expands support for 5G core network protocols. Network architects managing multi-tenant environments will benefit from its 30% reduction in east-west traffic latency and improved SSL inspection throughput (measured at 950 Gbps with NP8 acceleration).
Key Features and Improvements
1. Critical Vulnerability Remediation
- Patches CVE-2025-32758 (CVSS 9.3), a remote code execution flaw in SD-WAN API endpoints affecting unpatched devices since March 2025.
- Resolves CVE-2025-30125 (CVSS 8.7), an authentication bypass vulnerability in SAML/SSO integrations.
2. Network Performance Optimization
- Increases VXLAN tunnel capacity by 50% through enhanced NP8 processor load balancing (up to 12,000 concurrent tunnels supported).
- Reduces BGP convergence time to 8 seconds for routes exceeding 2 million entries.
3. Energy Efficiency Upgrades
- Lowers power consumption by 19% per 100Gbps throughput compared to v7.2.4 through dynamic voltage scaling.
- Introduces adaptive fan control algorithms reducing acoustic noise by 25% during off-peak hours.
4. 5G Core Network Compliance
- Validates 3GPP Release 19 network slicing policies with GTP-U header inspection at 400G line rate.
- Adds support for 5G non-standalone (NSA) to standalone (SA) migration workflows.
Compatibility and Requirements
| Category | Specifications |
|---|---|
| Supported Hardware | FortiGate 1800F, 1800F-2R |
| Minimum RAM | 256 GB DDR5 (512 GB recommended for IPS) |

Critical Notes:
- Incompatible with FortiSwitch 1000-series running firmware older than v7.2.3 due to STP protocol revisions.
- Requires BIOS v3.1.5 or newer for full NP8 offloading capabilities.
Limitations and Restrictions
-
Known Issues:
- Intermittent packet drops (0.005%) observed on 400G LR8 interfaces during sustained 980 Gbps traffic loads.
- SSL-VPN handshake failures may occur when using ECDSA certificates with 521-bit keys.
-
Performance Constraints:
- Maximum threat protection throughput limited to 600 Gbps when FIPS-CC mode is enabled.
- SD-WAN application steering temporarily disabled for IPv6 multicast traffic.
