The standard package of Anti-DDoS Pro provides DDoS protection based on standard HTTP ports (80, 8080) and HTTPS ports (443, 8443). The enhanced package supports non-standard HTTP and HTTPS ports. However, the number of ports used by each protected domain is subject to a limit.

Note To add non-standard HTTP or HTTPS ports, make sure that your domain is associated with an Anti-DDoS Pro instance of the enhanced package.

Port limit

The domains associated with each Anti-DDoS Pro instance of the enhanced package can use a maximum of 10 ports.

Supported ports

Note Anti-DDoS Pro only protects supported HTTP and HTTPS ports. The service does not protect or forward traffic from non-supported ports. For example, if an Anti-DDoS Pro instance receives a packet on port 4444, the packet will be directly discarded.
