Description:

Beginning with the 25R3 release, Fusion Data Intelligence (FDI) enforces a hard limit of 19 entries in the network Access Control List (ACL). This change moved ACL management from the Autonomous Data Warehouse (ADW) layer to the FDI application layer, effectively reducing flexibility for customers who require multiple IP/CIDR ranges for secure connectivity.

Our organization previously maintained 40+ IPs/CIDRs in our allowlist to support development, integration, and regional access needs. The new 19-entry limit has broken this functionality — we can no longer grant required access without broadening CIDR ranges, which directly conflicts with IT security best practices and increases our exposure surface.

Request:
We request that Oracle consider one or more of the following enhancements:

• Increase the ACL limit (e.g., to 100 entries or more), or
• Make the limit configurable per environment or tenancy, or
• Provide a grouping or NAT-based mechanism (e.g., network zones, shared profiles) to logically manage larger allowlists without reducing network security.

These changes would allow enterprise customers to maintain proper segmentation and control while remaining compliant with security policies and avoiding overly broad CIDRs.

Business Impact:

• Current limit prevents us from restoring previously functional access patterns.
• Impacts multiple developer and integration teams.
• Forces potential reduction of network security posture to remain operational.
