In the DDS, you can add a trustlist group for available instances in the following steps:
Go to the DDS Management Console.
Click Instance Management to go to the instance list page.
Click the name of an instance whose status is running to go to the instance details page.
On the Trustlist Management page, click Add Trustlist Group, enter the group name, access type, and allowed IP address list, and click OK to add the trustlist group.
Description
You can add IP CIDR in the format of X.X.X.X/X to the trustlist list.
If the value is set to 127.0.0.1, access from all addresses (including intranet and Internet addresses) are denied (default).
If the value is set to 0.0.0.0/0, the access IP address is not restricted.
When Intranet Access is selected as the access type, Internet access is impossible.
When instances are accessed from the Internet, you must add the Internet IP address to the group with access type being Internet Access.
