Create a Virtual NIC Set
You must create a virtual network interface card set (VNICset) in which to group all virtual network interface cards (vNICs) that you want to access over the VPN connection. Each instance (Oracle SOA Cloud Service and Oracle Database Cloud Service) has an associated vNIC. This task is a prerequisite for creating a VPN connection using VPN as a Service.
You can manage your VNICsets. See Managing vNICsets of Using Oracle Cloud Infrastructure Compute Classic.
