Step 3: Bind an EIP to a Load Balancer

After you configure a load balancer for your dedicated WAF instance, you need to 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.
