Anti-DDoS Pro and Anti-DDoS Premium instances that use the standard function plan support standard HTTP ports 80 and 8080 and standard HTTPS ports 443 and 8443 to protect websites against DDoS attacks. Instances that use the enhanced function plan support non-standard HTTP and HTTPS ports. However, only a limited number of ports are supported.

Note To support non-standard HTTP or HTTPS ports, make sure that your website is associated with an instance that uses the enhanced function plan.

Limit on the total number of ports

An instance that uses the enhanced function plan supports a maximum of 10 different ports.

Supported ports

Note Instances protect only the specific HTTP and HTTPS ports. Inbound traffic of unsupported ports is not scrubbed and forwarded. For example, Anti-DDoS Pro or Anti-DDoS Premium discards the inbound traffic of port 4444.
