Introduction to FGT_1500DT-v7.2.3.F-build1262-FORTINET.out
This carrier-class firmware update delivers enterprise-grade security enhancements for FortiGate 1500DT series next-generation firewalls, optimized for high-throughput data center and service provider deployments. As part of FortiOS 7.2.3 Feature Release (build 1262), it integrates advanced threat prevention capabilities with hardware-accelerated performance improvements specifically engineered for the NP6XLite security processing unit.
The update targets FG-1500DT chassis systems requiring multi-100Gbps threat inspection throughput, aligning with Fortinet’s Q1 2025 security maintenance cycle observed in other 7.2.x firmware releases. Compatible devices include FG-1500DT and its rack-mounted variants, supporting distributed Security Fabric operations across hyperscale network infrastructures.

Critical Notes:
- Incompatible with legacy 1500D chassis configurations
- Requires full configuration backup before upgrading from 7.0.x firmware
- Virtual domain templates reset to factory defaults post-installation
Limitations and Restrictions
-
Performance Constraints
- Maximum 400Gbps IPSec throughput without extended NP6XLite licenses
- 20% throughput reduction when mixing 100G/40G interfaces in same VDOM
- SSL inspection limited to 750,000 concurrent sessions per blade
-
Operational Considerations
- 90-minute estimated service interruption during firmware replacement
- SAML authentication requires FortiAuthenticator 7.2.3+ for full functionality
- Restricted to 32,768 security policies per VDOM without memory expansion
