Editing Server Information

If you select Cloud - CNAME or dedicated when adding a website to WAF, you can edit the server information of your website.

Applicable scenarios:
  • Edit server information.
    • Cloud - CNAME access: You can modify configurations for Client Protocol, Server Protocol, Server Address, and Server Port.
    • Dedicated mode: You can modify configurations for Client Protocol, Server Protocol, Server Address, VPC, and Server Port.
  • Add server configurations.
  • Update a certificate by referring to Updating a Certificate.

If you have enabled enterprise projects, ensure that you have all operation permissions for the project where your WAF instance locates. Then, you can select the enterprise project from the Enterprise Project drop-down list and configure server information for the domain names.
