Function Description

This function configures a server on the private network for access via a specific TCP port on the public network. The public world will know the server as ipPublic:portPublic. On the private network, the server will be implemented as ipPrivate:portPrivate.

The user may call this function as many times as desired. Be sure not to assign any conflicting public or private IP/port/protocol triads.

  The interface handle of the public NAT device on which to configure the public TCP port on.

Returns

• TM_ENOERROR

  Success.

• TM_EINVAL

• There is IP/port/protocol conflict.
