Troubleshooting Tip: CIDR Filter Not Working in Address Object Table on FortiOS v7.4.x

[kjay]

Description	This article describes an issue where the Address object table on FortiGate devices cannot be filtered using CIDR notation (for example, /24) after upgrading to v7.4.x.
Scope	FortiGate v7.4.
Solution	The address object table supports only simple string-based filters and lacks IP logic-based filters like contains or overlaps, causing searches with CIDR notation (for example, 1.1.1.0/24) to return inaccurate results. Test Environment. Tested on these versions: v7.2.8. v7.4.8. v7.6.4.   Reproduction Steps. Go to Policy & Objects -> Addresses. Create these address objects (IP Range/Subnet): 1.1.1.0/24. 1.1.1.1/32. 1.1.1.2/32. 1.1.1.3/32. In the search bar, type 1.1.1.0/24.   Results. v7.2.8: Shows matching results.                                                 v7.4.8: non-exact matches (issue occurs).                                                         v7.6.4: Shows matching results.                                                                         This behavior occurs only in v7.4.x and has been resolved in: v7.6.4 (available to download from the Fortinet support portal). v8.0.0 (scheduled to be released in February 2026). These timelines for firmware release are estimates and may be subject to change.
