Additionally, custom rules can be configured in the same WAF policy if you wish to bypass any of the pre-configured rules in the Default Rule Set.

The request is either blocked or passed through to the back-end. No other custom rules or the rules in the Default Rule Set are processed. You can also remove the Default Rule Set from your WAF policies.
