INetFwPolicy2::put_UnicastResponsesToMulticastBroadcastDisabled method (netfw.h)

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

This property is read/write.

Syntax

HRESULT put_UnicastResponsesToMulticastBroadcastDisabled(
  NET_FW_PROFILE_TYPE2 profileType,
  VARIANT_BOOL         disabled
);

Parameters

profileType

disabled

Return value

None

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.
