An IP Access rule can perform one of the following actions:
Block: Prevents a visitor from visiting your site.
Allow: Excludes visitors from all security checks, including Browser Integrity Check, I’m Under Attack Mode, and the WAF. Use this option when a trusted visitor is being blocked by Cloudflare’s default security features. The Allow action takes precedence over the Block action. Note that allowing a given country code will not bypass the Cloudflare Web Application Firewall (WAF) .
Managed Challenge: Depending on the characteristics of a request, Cloudflare will dynamically choose the appropriate type of challenge from a list of possible actions. For more information, refer to Cloudflare challenges.
Interactive Challenge: Requires the visitor to complete an interactive challenge before visiting your site. Prevents bots from accessing the site.
