The details of the forwarding rule. The value is a string that consists of JSON arrays. Each element in a JSON array is a JSON struct that contains the following fields:

• ProxyRules: the information about the origin server. The information includes the port number and IP address. This field is required and must be a JSON array. Each element in a JSON array is a JSON struct that contains the following fields:
  • ProxyPort: the port number. This field is required and must be an integer.

The ID of the associated defense. This parameter applies to scenarios in which other cloud services, such as Object Storage Service (OSS), are integrated with Anti-DDoS Pro or Anti-DDoS Premium.

For example, if you integrate OSS with Anti-DDoS Pro or Anti-DDoS Premium, Anti-DDoS Pro or Anti-DDoS Premium allocates an IP address pool for the OSS production account. Each IP address corresponds to a unique defense ID. A defense ID is a CNAME, which is automatically resolved to the IP address of the required Anti-DDoS Pro or Anti-DDoS Premium instance. A defense ID can be resolved to the same IP address to facilitate scheduling.
