HIP

By default, the Oracle® Enterprise Session Border Controller’s ICMP, SNMP, and SSH services cannot be accessed via the media interfaces. In order to enable these services, you must explicitly configure access by identifying valid source addresses for the specific applications. Doing such uses the Oracle® Enterprise Session Border Controller's host-in-path (HIP) functionality.

When traffic is received on media interfaces, it is scanned for ICMP, SNMP, or SSH packets. The configuration is set to identify the possible IP addresses where that traffic may be sourced from. When a match is made among packet type and source address, those packets are forwarded through the media interfaces to the processes running on the system's CPU.

Each media network-interface's gateway should be configured so that off-subnet return traffic can be forwarded out the appropriate media interface. Also, it is advisable that no overlapping networks are configured between any media network interface and the administrative interfaces (wancom).
