The IPFilterSecurityEnabled property indicates whether IP port security is enabled globally across all IP-bound network adapters. This property is used in conjunction with IPSecPermitTCPPorts, IPSecPermitUDPPorts, and IPSecPermitIPProtocols. A value of TRUE indicates that IP port security is enabled and that the security values associated with individual network adapters are in effect. A value of FALSE indicates IP filter security is disabled across all network adapters and allows all port and protocol traffic to flow unfiltered.
