dwIPv4NegotiationError: Specifies if an Internal IPv4 address [RFC4306] has been successfully assigned. A value of zero (0) indicates success. A nonzero value indicates failure.

wszAddress: The same as wszAddress in PPP_PROJECTION_INFO_1.

wszRemoteAddress: The same as wszRemoteAddress in PPP_PROJECTION_INFO_1.

IPv4SubInterfaceIndex: The same as IPv4SubInterfaceIndex in PPP_PROJECTION_INFO_1.

dwIPv6NegotiationError: The same as dwIPv5NegotiationError in PPP_PROJECTION_INFO_1.

bInterfaceIdentifier: The same as bInterfaceIdentifier in PPP_PROJECTION_INFO_1.

bRemoteInterfaceIdentifier: The same as bRemoteInterfaceIdentifier in PPP_PROJECTION_INFO_1.

bPrefix: The same as bPrefix in PPP_PROJECTION_INFO_1.

dwPrefixLength: The same as dwPrefixLength in PPP_PROJECTION_INFO_1.

IPv6SubInterfaceIndex: The same as IPv6SubInterfaceIndex in PPP_PROJECTION_INFO_1.

dwOptions: Not used.

dwAuthenticationProtocol: Specifies the authentication protocol used to authenticate the remote computer. It MUST be one of the following values.

Value	Meaning
MPRAPI_IKEV2_AUTH_USING_CERT 0x00000001	Using x.509 machine certificate [RFC2459].
MPRAPI_IKEV2_AUTH_USING_EAP 0x00000002	Extensible Authentication Protocol (EAP).

dwEapTypeId: Specifies the type identifier of the EAP used to authenticate the local computer. The value of this member is valid only if dwAuthenticationProtocol is MPRAPI_IKEV2_AUTH_USING_EAP [IANA-EAP].

dwCompressionAlgorithm: Not used.

dwEncryptionMethod: Specifies the encryption method used in the connection. It MUST be one of the following values.

Value	Meaning
IPSEC_CIPHER_TYPE_3DES 2	Specifies 3DES encryption.
IPSEC_CIPHER_TYPE_AES_128 3	Specifies AES-128 encryption.
IPSEC_CIPHER_TYPE_AES_192 4	Specifies AES-192 encryption.
IPSEC_CIPHER_TYPE_AES_256 5	Specifies AES-256 encryption.
