Configure a multi-line Anti-DDoS Pro instance to pass traffic back to multiple origin sites

Last Updated: Nov 05, 2018

In cases where compliance or high availability is required, you can deploy a multi-line Anti-DDoS Pro instance to pass traffic back to different origin sites, based on the type of line. For example, you can enable the China Telecom line of your Anti-DDoS Pro instance for a China Telecom origin, and the China Unicom line for a China Unicom origin. This document describes the configuring method in the Anti-DDoS console.

Prerequisites

If your domain name is not connected to an Anti-DDoS Pro instance, follow HTTP website access or HTTPS website access to connect your domain name to Anti-DDoS Pro.

Procedure

Note: We recommend that you familiarize yourself with the configuration procedure, before performing the actual configuration and only do so during off-peak hours.

Follow these steps to have an Anti-DDoS Pro instance pass traffic back to multiple origin sites.

  1. Log on to the Anti-DDoS Pro console, and then go to Access > Web Service.

  2. Locate the target domain name, and then click Origin Edit under Domain Info.

  3. Disable certain lines for the current origin.

    For example, if you want to only use the BGP lines for domain name resolution for the current origin, you can disable the China Telecom and China Unicom lines. Follow these steps to disable the China Telecom and China Unicom lines:

    1. On the Anti-DDoS IP/Domain Resolution Switch column, toggle off the China Telecom and China Unicom lines.

    2. Click Edit IP on the Operation list.

    3. On the Edit IP page, click OFF to disable certain lines, for which you have toggled domain name resolution off. In this case, disable China Telecom and China Unicom lines.

    4. Click OK.

      When completing the configuration, you can find that the China Telecom and China Unicom lines are removed on the Anti-DDoS IP/Domain Resolution Switch column.

  4. Add a new origin and enable other lines for it. For example, you can add a China Telecom origin, and enable the China Telecom line for it. Follow these steps to add a China Telecom origin and configure the China Telecom line.

    1. On the Origin Edit page, click Add.

    2. Select the Origin site IP mode and enter an IP address.

    3. Click ON under the China Telecom line.

    4. Click OK.

      With the preceding configuration, your Anti-DDoS Pro instance’s China Telecom line directs requests back to the newly added China Telecom origin.

  5. Follow Step 4 to configure other lines of your Anti-DDoS Pro instance for the corresponding origins. Make sure that different lines are enabled for their corresponding origins.
