Step 3: Bind an EIP to a Load Balancer

If you configure a load balancer for your dedicated WAF instance, unbind the EIP from the origin server and then bind this EIP to the load balancer you configured. For details, see Configuring a Load Balancer. The request traffic then goes to the dedicated WAF instance for attack detection first and then go to the origin server, ensuring the security, stability, and availability of the origin server.

This topic describes how to unbind an EIP from your origin server and bind the EIP to a load balancer configured for a dedicated WAF instance.

Prerequisites

You have configured a load balancer for a dedicated WAF instance.

  2. Click in the upper left corner of the management console and select a region or project.
  3. Click in the upper left corner of the page and choose Elastic Load Balance under Network to go to the ELB console.
  4. On the Load Balancers page, unbind the EIP from the origin server.
