OFFLOAD_IPSEC_UDPESP_ENCAPTYPE_ENTRY (Compact 2013)

  • [アーティクル]

3/26/2014

This structure specifies the UDP-ESP encapsulation type and destination port of a parser entry.

Syntax

typedef struct _OFFLOAD_IPSEC_UDPESP_ENCAPTYPE_ENTRY {
  UDP_ENCAP_TYPE  UdpEncapType;
  USHORT  DstEncapPort;
} OFFLOAD_IPSEC_UDPESP_ENCAPTYPE_ENTRY, *POFFLOAD_IPSEC_UDPESP_ENCAPTYPE_ENTRY;

Members

  • UdpEncapType
    The UDP-ESP encapsulation type for packets protected by the security associations (SAs) that are being offloaded:

    • IPSEC_UDPESP_ENCAPTYPE_IKE
      This value is reserved.
    • IPSEC_UDPESP_E\NCAPTYPE_OTHER
      UDP encapsulation for packets on port 4500. For more information, see UDP-ESP Encapsulation Types.
  • DstEncapPort
    For an inbound SA (Flags = OFFLOAD_INBOUND_SA), specifies the destination port that the network adapter should look for in the UDP header of inbound packets that it processes on the SAs being offloaded. The network adapter should ignore this member for an outbound SA (Flags = OFFLOAD_OUTBOUND_SA). DstEncapPort should always specify port 4500.

Remarks

The OFFLOAD_IPSEC_UDPESP_ENCAPTYPE_ENTRY structure is used with the OFFLOAD_IPSEC_ADD_UDPESP_SA structure.
