When a source IP initiates a number of abnormal connections that exceed the threshold, Anti-DDoS can automatically block the IP. After the abnormal connection protection is enabled, if a source IP sends a large volume of messages with abnormal connection status frequently in a short period, the source IP will be blocked for 15 minutes and recovered automatically after that.
Purchase an Anti-DDoS Advanced instance and set the object to be protected.
- Log in to the Anti-DDoS console and click Anti-DDoS Advanced (New) -> Configurations on the left sidebar.
- Select the ID or port of a protected IP from the left list, e.g., 212.64.xx.xx bgpip-000002jt or 119.28.xx.xx bgpip-000002ju -> tcp:8000. Click Set in the Abnormal Connection Protection section to enter the abnormal connection protection list.
- Click Create.
- In the pop-up window, enable the protection and click OK.
- Now the new abnormal connection protection rule is added to the list, and you can click Configuration to modify it.
