Do I Have to Configure the Same Port as That of the Origin Server When Adding a Website to WAF?
No. When you add a domain name to WAF, configure the server port to the port of the protected website. The origin server port is the service port used by WAF to forward your website requests. More details about port configuration are described as follows:
- If Client Protocol is HTTP, WAF protects services on the standard port 80 by default. If Client Protocol is HTTPS, WAF protects services on the standard port 443 by default.
- To configure a port other than ports 80 and 443, select a non-standard port from the Protected Port drop-down list.
For details about the non-standard ports supported by WAF, see Which Non-Standard Ports Does WAF Support?
