VC编写 防火墙 源代码

VC 编写 防火墙 源代码， 注解非常详细 inFilter.dwFilterFlags = FD_FLAGS_NOSYN; //一直添这个值 inFilter.dwRule = 0; //一直添这个值 inFilter.pfatType = PF_IPV4; //用 ipV4 地址 inFilter.SrcAddr = localIp; //设置本地IP地址 inFilter.wSrcPort = FILTER_TCPUDP_PORT_ANY; //任意来源端口 inFilter.wSrcPortHighRange = FILTER_TCPUDP_PORT_ANY; inFilter.DstAddr = 0; //任意目标地址 inFilter.DstMask = 0; inFilter.wDstPort = FILTER_TCPUDP_PORT_ANY; //任意目标端口 inFilter.wDstPortHighRange =FILTER_TCPUDP_PORT_ANY; inFilter.dwProtocol = FILTER_PROTO_TCP; // 过滤的协议，可选FILTER_PROTO_ICMP // 加入一个过滤接口
