You can modify the origin IP address as needed once you enable a non-web service or web service in Anti-DDoS Pro.

Follow these steps to modify the origin IP address for a non-Web service:
  1. Log on to the Anti-DDoS Pro console and go to the Access > Non-Web Service page.
  2. Select an Anti-DDoS instance and corresponding IP address.
  3. Locate the target Forwarding protocol/port, and then click Edit under the Operation column of the protocol/port.
  4. Enter a new Origin site IP, and then click OK under the Operation column.
Note If the non-Web service owns multiple lines, the forwarding rules for all the lines must be modified.

Web Service

Follow these steps to modify the origin IP address for a Web service:
  1. Log on to the Anti-DDoS Pro console and go to the Access > Non-Web Service page.
  2. Locate the domain name to be configured, and then click Origin Edit under the Domain Info column of the target domain name.
  3. Click Edit Origin IP under the Operation column.
  4. Enter a new Origin site IP, and then click OK.
Note When the modification is completed, the website takes some time to apply the configuration. During this period, the access requests are still forwarded to the former origin IP address. After the configuration is completed, access requests are forwarded to the new origin IP.
