Network Requirements
The Gateway server must have at least one interface configured with an IPv4 address that is used to communicate to the Internet and the Oracle endpoints. You can add more interfaces to the Gateway to support systems that are not accessible from the primary interface. These interfaces can support either IPv4 or IPv6.
Note - When IPv6 addresses are added to the primary interface, you are not required to add a physically separate cable to support internal IPv6 networks and IPv4 communication to the Oracle endpoints.
The diagram below depicts an example network configuration featuring an internal customer network and Oracle that incorporates both IPv4 and IPv6.
