Blocking Traffic of a Specified Protocol
Advanced Anti-DDoS offers a one-click mode to block inbound traffic based on protocol type. If you do not deploy UDP services, you are advised to disable the UDP protocol.
Once UDP protocol blocking is enabled, the policy applies directly to the specified Advanced Anti-DDoS instance. If access traffic exceeds 2 Mbit/s, the system automatically rate-limits UDP traffic.
Policy Validity
Once configured, the policy remains in effect permanently.
