Members

dwIPv4NegotiationError

A value that specifies the result of IPv4 negotiation. A value of zero indicates an IPv4 address has been assigned successfully. A nonzero value indicates failure, and is the fatal error that occurred during negotiation.

wszAddress[IPADDRESSLEN + 1]

An null-terminated Unicode string that specifies the IPv4 address of the local client. The string has the form "a.b.c.d". The wszAddress member is valid only if the dwIPv4NegotiationError member is 0.

wszRemoteAddress[IPADDRESSLEN + 1]

A null-terminated Unicode string that specifies the IPv4 address of the remote server. This string has the form "a.b.c.d". The wszRemoteAddress member is valid only if the dwIPv4NegotiationError member is zero. If the address is not available, this member is an empty string.

IPv4SubInterfaceIndex

A value that specifies the IPv4 subinterface index corresponding to the connection on the server.

dwIPv6NegotiationError

A value that specifies the result of IPv6 negotiation. A value of 0 indicates an IPv6 address has been negotiated successfully. A nonzero value indicates failure, and is the fatal error that occurred during negotiation.

bInterfaceIdentifier[8]

An array that specifies the 64-bit IPv6 interface identifier of the client. The last 64-bits of a 128-bit IPv6 internet address are considered the interface identifier, which provides a strong level of uniqueness for the preceding 64-bits. The bInterfaceIdentifier member is valid only if the dwIPv6NegotiationError member is 0. The bInterfaceIdentifier member must not be 0.

bRemoteInterfaceIdentifier[8]

An array that specifies the 64-bit IPv6 interface identifier of the server. The last 64 bits of a 128-bit IPv6 internet address are considered the interface identifier, which provides a strong level of uniqueness for the preceding 64 bits. The bInterfaceIdentifier member must not be 0 and is valid only if the dwIPv6NegotiationError member is zero.

bPrefix[8]

A value that specifies the client interface IPv6 address prefix.

dwPrefixLength

A value that specifies the length, in bits, of the bPrefix member.

IPv6SubInterfaceIndex

A value that specifies the IPv6 subinterface index corresponding to the connection on the server.

dwOptions

Not implemented.

dwAuthenticationProtocol

A value that specifies the authentication protocol used to authenticate the remote server. The following authentication protocols are supported:

Value Meaning
MPRAPI_IKEV2_AUTH_USING_CERT
 X.509 Public Key Infrastructure Certificate (described in RFC 2459)
MPRAPI_IKEV2_AUTH_USING_EAP
 Extensible Authentication Protocol

dwEapTypeId

A value that specifies the type identifier of the Extensible Authentication Protocol (EAP) used to authenticate the local client. The value of this member is valid only if the dwAuthenticationProtocol member is MPRAPI_IKEV2_AUTH_USING_EAP.

dwEmbeddedEAPTypeId

A value that specifies the type identifier of the inner EAP method used in the EAP authentication. The value of this member is valid only if the dwEapTypeId member is set to PEAP defined in IANA-EAP.

dwCompressionAlgorithm

Not implemented.

dwEncryptionMethod

A value that specifies the encryption method used in the connection. The following encryption methods are supported:

Value Meaning
IPSEC_CIPHER_TYPE_3DES
 3DES encryption
IPSEC_CIPHER_TYPE_AES_128
 AES-128 encryption
IPSEC_CIPHER_TYPE_AES_192
 AES-192 encryption
IPSEC_CIPHER_TYPE_AES_256
 AES-256 encryption
