Anti-DDoS Pro supports IP blocklist and allowlist configurations to block or allow source IPs to access the Anti-DDoS service, restricting the users from accessing your business resources. For the allowed IPs, they are allowed to access without being filtered by any protection policy; while the access requests from the blocked IPs are directly denied.

Prerequisites

You have successfully purchased an Anti-DDoS Pro instance and set the protected target.

Note：

• The IP blocklist and allowlist filtering take effect only when your business is under DDoS attacks.
• The allowed IPs will be allowed to access resources without being filtered by any protection policy.
• The access requests from the blocked IPs will be directly denied.

Operation Directions

1. Log in to the new Anti-DDoS console and select Anti-DDoS Pro (New) > Configurations on the left sidebar. Open the DDoS Protection tab.
2. Select an Anti-DDoS Pro instance ID in the list on the left, such as "bgp-00xxxxxx".
   
3. Click Set in the IP Blocklist/Allowlist section.
   
4. In the pop-up window, tick Blocklist or Allowlist as the type, enter the target IP, and click OK.
   
5. After the rule is created, it is added to the list. You can click Delete on the right of the rule to delete it.
