INetFwPolicy2::UnicastResponsesToMulticastBroadcastDisabled property

Indicates whether the firewall should not allow unicast responses to multicast and broadcast traffic.

This property is read/write.

Syntax


HRESULT put_UnicastResponsesToMulticastBroadcastDisabled(
  [in]   NET_FW_PROFILE_TYPE2 profileType,
  [in]   VARIANT_BOOL disabled
);

HRESULT get_UnicastResponsesToMulticastBroadcastDisabled(
  [in]   NET_FW_PROFILE_TYPE2 profileType,
  [out]  VARIANT_BOOL *disabled
);

Property value

True if the firewall should not allow unicast responses to multicast and broadcast traffic.

Error codes

If the method succeeds, the return value is S_OK.

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

NameMeaning
E_ACCESSDENIED

The operation was aborted due to permissions issues.

E_INVALIDARG

The method failed due to an invalid parameter.

E_OUTOFMEMORY

The method was unable to allocate required memory.

E_POINTER

The method failed due to an invalid pointer.

Remarks

If a computer sends a broadcast packet, a unicast response is allowed for three seconds. Use this property to change this behavior.

When you pass a profile type obtained from the CurrentProfileTypes property (get_CurrentProfileTypes), make sure that you pass only one profile type to get_UnicastResponsesToMulticastBroadcastDisabled and put_UnicastResponsesToMulticastBroadcastDisabled. Note that get_CurrentProfileTypes can return multiple profiles.
