I'm sorry, but the provided knowledge sources do not contain specific information on how to set the rate limit configuration in a self-hosted Ory Kratos setup. However, they do mention that when using Ory Network, protections against brute-force attacks, such as rate limiting requests to API public endpoints, are provided as part of the platform's security infrastructure. When self-hosting the Ory Kratos Identity Server, it's the responsibility of the administrator to implement and manage rate limiting or other measures to ensure the security of the network ([source](https://www.ory.sh/docs/kratos/concepts/security#defenses-against-brute-force-attacks)). For more detailed instructions on configuring Ory Kratos, you may want to refer to the [official Ory Kratos configuration documentation](https://www.ory.sh/docs/kratos/configuring). If you need further assistance, consider reaching out to [Ory Support](https://www.ory.sh/support/).
