Restrict Access to an Instance
Restrict the networks that have access to your Oracle Integration instance, including File Server, by configuring an allowlist (formerly a whitelist). Only users from the specific IP addresses, Classless Inter-Domain Routing (CIDR) blocks, and virtual cloud networks that you specify can access the Oracle Integration instance and File Server.
For the Oracle Integration instance, configure the allowlist when you create the instance or after creating the instance. For File Server, configure the allowlist when you enable File Server or at any time afterward.
