Web Application Firewall:View the ports supported by WAF

Precautions

• WAF protects services that use standard or non-standard ports. The number of ports and the range of non-standard ports that are supported by a WAF instance vary based on the WAF edition. For more information, see Ports supported by each WAF edition.

• The maximum number of ports supported by a WAF instance is the total number of standard and non-standard ports supported by the instance.

• If you use a WAF instance of the Exclusive edition or add a website to WAF in transparent proxy mode, WAF supports all non-standard ports. In other cases, WAF supports only specific non-standard ports.

View the supported ports in the WAF console

1. Log on to the WAF console and go to the Website Configuration page.

2. Find the domain name that you want to manage and click Edit in the Actions column.

3. In the Edit Domain Name panel, find the HTTP Port section and click View Port Range.

For more information, see Specify ports.

Ports supported by each WAF edition

• Transparent proxy mode: WAF instances support any non-standard ports from 0 to 65535.

  Note

  The number of traffic redirection ports that are supported in transparent proxy mode is limited. For more information, see Transparent proxy mode.

• CNAME record mode: Only subscription WAF instances of the Business, Enterprise, or Exclusive edition support non-standard ports.

  The following table lists the ports that are supported by each WAF edition in CNAME record mode. The supported ports in the console shall prevail. For more information about how to view the supported ports in the console, see Specify ports.
