On this page, you can configure URL filter parameters. If the Enable smart URL filter check box is selected and multiple domains correspond to the same IP address, access to the IP address is restricted.
For example, three domain names huawei1, huawei2, and huawei3 correspond to the same IP address 10.1.1.1, and huawei1 is blacklisted. If smart URL filter function is enabled, access to huawei1 and 10.1.1.1 is restricted. If the smart URL filter function is disabled, only access to huawei1 is restricted.
