ACME External Account Binding (EAB) Support 7.6.7
FortiADC now supports the Automated Certificate Management Environment (ACME) External Account Binding (EAB) protocol extension. While standard ACME typically only verifies domain ownership, EAB allows FortiADC to securely link its automated ACME client to existing, pre-registered accounts with commercial Certificate Authorities (CAs) such as DigiCert, ZeroSSL, or Sectigo. This ensures that only authorized clients can request certificates under a specific account profile, enabling organizations to utilize paid CA services, manage centralized billing, and enforce organizational validation (OV/EV) policies that are not available through standard free ACME services.
Server Load Balance
Stream Scripting Support for Session Persistence 7.6.7
FortiADC 7.6.7 expands the capabilities of the Stream Scripting engine to include native session persistence management within L7 TCP/UDP Virtual Servers. Previously, using stream scripts and persistence together could lead to initialization conflicts where script logic would override standard persistence settings. This update resolves those conflicts by allowing the LB method, LB persistence, and Lua scripting modules to work in coordination. This introduces specialized Lua API commands and events that allow administrators to programmatically control how sessions are stored in and retrieved from the persistence table.
Global Load Balance
GLB Scalability for Multi-User Environments 7.6.7
To improve multi-tenancy capabilities and support large-scale deployments, FortiADC 7.6.7 has standardized and increased the maximum configuration values for key Global Load Balancing (GLB) objects to 4096 across all platforms. Previously, these configuration limits varied depending on the hardware or virtual machine (VM) platform capacity. This update ensures uniform scalability and consistent performance for high-density environments regardless of the appliance model.
Platform
OpenSSL Upgrade to 3.3.7 for Improved Security 7.6.7
FortiADC 7.6.7 upgrades the OpenSSL library to version 3.3.7 to align with the latest security compliance requirements and upstream fixes.
