The IP_NAT_MIB_QUERY structure is used to retrieve Network Address Translator (NAT) information and is passed to the following methods:

• RMIBEntryGet (section 3.1.4.30) 

• RMIBEntryGetFirst (section 3.1.4.31)

• RMIBEntryGetNext (section 3.1.4.32) 

   typedef struct _IP_NAT_MIB_QUERY {
     ULONG Oid;
     union {
       ULONG Index;
       UCHAR Data;
     };
   } IP_NAT_MIB_QUERY,
    *PIP_NAT_MIB_QUERY;
  

Oid: This is an index of the NAT MIB. It MUST be one of the following values.

Value	Meaning
IP_NAT_INTERFACE_STATISTICS_OID 0x00000000	NAT interface statistics information is retrieved. When RMIBEntryGet, RMIBEntryGetFirst, and RMIBEntryGetNext return pMibOutEntry or pInfoStruct it MUST be typecast to IP_NAT_INTERFACE_STATISTICS (section 2.2.1.2.185).
IP_NAT_INTERFACE_MAPPING_TABLE_OID 0x00000001	NAT interface mapping table information. When RMIBEntryGet, RMIBEntryGetFirst, and RMIBEntryGetNext return pMibOutEntry or pInfoStruct it MUST be typecast to IP_NAT_ENUMERATE_SESSION_MAPPINGS (section 2.2.1.2.183).
IP_NAT_MAPPING_TABLE_OID 0x00000002	NAT mapping table information. Retrieves the session mappings of an interface. When RMIBEntryGet, RMIBEntryGetFirst, and RMIBEntryGetNext return pMibOutEntry or pInfoStruct it MUST be typecast to IP_NAT_ENUMERATE_SESSION_MAPPINGS.

Index: This MUST be the index of the interface when Oid is 0x00000000.

Data: This MUST be IP_NAT_ENUMERATE_SESSION_MAPPINGS if Oid is not 0x00000000.
