The Custom Rules screen enables you to upload WAF Custom Rules (.conf) and associated WAF Custom Rule Data (.data or .txt) files. The first character in the filename must be an alpha character or an underscore (_). The other characters in the filename can include full stops (.) or dashes (-). You can also upload gzip-compressed Tarball files (.tar.gz), which contain multiple rule and data files.

Note: We do not recommend using the WAF rule "redirect" action in custom rules because of the impact this has on system performance. You should use content rules instead for that purpose.

Installed Rules: Choose File.

Individual custom rules can be uploaded as .conf files. Alternatively, you can load a package of rules in a .tar.gz file. After selecting the rule files to be uploaded, click the Add Ruleset button.

WAF Custom Rule Data : Choose File.

Upload any additional data files with associated data for the rules.

The additional files are for the rules’ associated data files. If you uploaded a Tarball when uploading the rules, the rules and data files can be packaged together. After selecting the data files to be uploaded, click the Add Data File button.

Note: Custom rules and data files can be deleted or downloaded by clicking the relevant buttons.
Note: If a rule is assigned to a Virtual Service, it will not be available for deletion.
