Web Application Firewall (WAF) protects services that use standard ports and non-standard ports. The standard ports are 80, 8080, 443, and 8443. The non-standard ports must be supported by WAF. You can specify non-standard ports for the origin server when you configure WAF for your website. WAF receives and forwards traffic on the ports that you specify.
- The maximum number of ports that a WAF instance supports is the total number of standard and non-standard ports that the instance supports.
- You can use all the non-standard ports only when you use a WAF instance of the Exclusive edition.In other cases, you can use only the non-standard ports that are supported by WAF.
View the supported ports in the WAF console
- In the left-side navigation pane of the WAF console, choose .
- Find the domain name for which you want to specify ports and click Edit in the Actions column.
- On the Edit page, find the Destination Server Port section, click Customize, and then enter port numbers based on your business requirements.
