When you add a domain name to Web Application Firewall (WAF) in CNAME record mode, you must use the HTTP or HTTPS ports that are supported by WAF. This topic describes the HTTP and HTTPS ports that are supported by the CNAME record mode.

Scenarios

WAF requires specific ports that your web service uses only when you add a domain name to WAF in CNAME record mode.
Notice If you add a domain name to WAF in cloud native mode, WAF protects traffic on the ports in the range of 0 to 65535.

When you add a domain name to WAF in CNAME record mode, you must specify the HTTP or HTTPS ports for the domain name in the Configure Listener step of the Add Domain Name wizard. You must specify ports within the port range supported by WAF. Otherwise, you cannot add your domain name to WAF in CNMAE record mode for protection. For more information, see Configuration wizard description.
