2.2.3.2 Interface Configuration
The interfaces that are present on the RRAS server MUST be stored under the registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RemoteAccess\Interfaces
with each subkey representing the configuration information pertaining to one interface. The subkeys MUST be named with a zero-based index in a monotonically increasing order. For example, if there are three interfaces in the system, the registry keys will be as follows.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RemoteAccess\Interfaces\0
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RemoteAccess\Interfaces\1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RemoteAccess\Interfaces\2
Under each interface-specific registry key, there SHOULD be transport-specific subkeys that contain the interface-specific configuration information pertaining to the transport. For example, the IPv4 transport-specific information for an interface with index 4 will be stored under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RemoteAccess\Interfaces\4\IP
