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.
