How Do I Check Whether a Back-to-Origin IP Address Has Been Whitelisted on My Origin Server?

Check servers and security devices to ensure that they have whitelisted the back-to-origin IP addresses and will not limit or block access traffic. For example:

  • If your origin servers are HUAWEI CLOUD servers, configure ACLs and security groups to permit the back-to-origin IP addresses.
    1. Log in to the management console.
    2. Click in the upper left corner of the management console and select a region or project.
    3. Click in the upper left corner of the page and choose Networking > Virtual Private Cloud.
    4. Add a security group rule to allow traffic to the back-to-origin IP address. For details, see Adding a Security Group Rule.
    5. Add a network ACL rule to allow access from the back-to-origin IP address. For details, see Creating a Network ACL.
  • If your origin servers already have their own security policies, ensure that they have taken effect. Some custom security policies may take effect only after a restart.
