UDP端口复制-SharpPCap BSOD

我用sharppcap编写了一个简单的程序,将输入的udp数据包复制到另一个端口。假设,我在端口25000上有输入数据包,我将使用sharppcap接收它们,创建与prevoius相同的新以太网数据包,只将目标端口更改为27000,然后发送数据包。

但过了一段时间,有时是1小时,有时是2小时,有时是12小时,我会得到BSOD。我不知道到底是什么导致了BSOD(在minidump中,我只知道它的内核和硬件抽象层)在地址树中,第一个if“ipnat.sys系统".

device.OnPacketArrival += new PacketArrivalEventHandler(device_OnPacketArrival);
            // Open the device for capturing
            device.Open();
            device.Filter = $"udp dst port {_portIncomming} and ip src not {_ipSource}";
            // Start capture 'INFINTE' number of packets
            device.Capture();
            // Close the pcap device
            // (Note: this line will never be called since
            //  we're capturing infinite number of packets
            device.Close();

并接收:

private static void device_OnPacketArrival(object sender, CaptureEventArgs e)
        {
            var device = e.Device;
            var packet = Packet.ParsePacket(e.Packet.LinkLayerType, e.Packet.Data);
            if (packet is EthernetPacket)
            {
                var eth = packet.Extract<EthernetPacket>();
                var ip = eth.Extract<IPPacket>();
                if (ip != null)
                {
                    var udp = packet.Extract<UdpPacket>();
                    device.SendPacket(CreateDuplicate(eth.SourceHardwareAddress, eth.DestinationHardwareAddress, udp.PayloadData, ip.SourceAddress, ip.DestinationAddress));                                        
                }                                
            }
        }

和CreateDuplicate:

private static EthernetPacket CreateDuplicate(PhysicalAddress source, PhysicalAddress dest, byte[] data, IPAddress ipSource, IPAddress ipDest)
        {
            ushort udpSourcePort = _portIncomming;
            ushort udpDestinationPort = _newDestPort;
            var udpPacket = new UdpPacket(udpSourcePort, udpDestinationPort);

            var ipSourceAddress = ipSource;
            var ipDestinationAddress = ipDest;
            var ipPacket = new IPv4Packet(ipSourceAddress, ipDestinationAddress);                       

            var ethernetSourceHwAddress = source;
            var ethernetDestinationHwAddress = dest;

            // NOTE: using EthernetPacketType.None to illustrate that the Ethernet
            //       protocol type is updated based on the packet payload that is
            //       assigned to that particular Ethernet packet
            var ethernetPacket = new EthernetPacket(ethernetSourceHwAddress,
                ethernetDestinationHwAddress,
                EthernetType.None);

            // Now stitch all of the packets together
            udpPacket.PayloadData = data;
            udpPacket.ParentPacket = ipPacket;
            ipPacket.PayloadPacket = udpPacket;
            ethernetPacket.PayloadPacket = ipPacket;

            ipPacket.UpdateIPChecksum();
            udpPacket.Checksum = udpPacket.CalculateUdpChecksum();
            ethernetPacket.UpdateCalculatedValues();

            //byte[] packetBytes = ethernetPacket.Bytes;
            return ethernetPacket;
        }

你有什么想法或一些提示或已经编写的程序来解决我的问题。 运行操作系统:Windows Server 2012 R2
