Technical Tip: How many Source IP's/URL can be added in one custom rule filter
| Description | This article shares information about custom rule filter length limitation when using the filter. |
| Scope | FortiAppSec Cloud. |
| Solution | For example, an application requires 'Source IP' as a filter. In this filter, one can also define IP address or Subnet range. The filter value has a length limitation (<=255 characters), so the amount depends on the length of each IP/IP range.
All IPs are like 1.1.1.1, 1 holding 1 character, then at most 31 IP addresses can be added and if all IPs are like 123.123.123.123, 1 holding 3 characters, then at most 16 IP addresses can be added in one custom rule filter.
To configure Custom rule from GUI:
Note: One application can be configured with a maximum of 12 custom rules. |
