Syntax

HRESULT AddPortMapping(
  [in]  BSTR                   bstrName,
  [in]  UCHAR                  ucIPProtocol,
  [in]  USHORT                 usExternalPort,
  [in]  USHORT                 usInternalPort,
  [in]  DWORD                  dwOptions,
  [in]  BSTR                   bstrTargetNameOrIPAddress,
  [in]  ICS_TARGETTYPE         eTargetType,
  [out] INetSharingPortMapping **ppMapping
);

Parameters

[in] bstrName

Pointer to a BSTR variable that contains the name for this port mapping.

[in] ucIPProtocol

NAT_PROTOCOL_TCP

NAT_PROTOCOL_UDP

[in] usExternalPort

[in] bstrTargetNameOrIPAddress

Pointer to a BSTR variable that contains the name of the target computer for this port mapping. Specify either the target name or the target IP address, but not both.

[in] eTargetType

Indicates target type.

[out] ppMapping

Pointer to a pointer that, on successful return, points to an INetSharingPortMapping interface for the port mapping.

Return value

If the method succeeds the return value is S_OK.

If the method fails, the return value is one of the following error codes.

Remarks

When first added, the new mapping is in a disabled state. To enable the new mapping, use INetSharingPortMapping::Enable.

After it is added, the new definition appears in the Port Mappings list in the ICS/ICF user interface.

Use the INetSharingManager::get_INetSharingConfigurationForINetConnection method to obtain an INetSharingConfiguration interface for a particular connection.
