Question

我正在尝试使用teredo interface构建基于UDP的p2p c＃应用程序，我设法使用以下命令在我的Windows 7操作系统上启用此接口：

netsh interface teredo>set state client teredo.remlab.net 60 23456

并在激活后打印出netsh interface teredo>show state命令：

Type                    : client
Server Name             : teredo.remlab.net
Client Refresh Interval : 60 seconds
Client Port             : 23456
State                   : qualified
Client Type             : teredo client
Network                 : unmanaged
NAT                     : symmetric (port)
NAT Special Behaviour   : UPNP: Yes, PortPreserving: No
Local Mapping           : 192.168.8.100:23456
External NAT Mapping    : 188.247.74.161:37457

使用打印的ping -t -6 www.google.com命令ping：基于google ipv6的主机：

Pinging www.google.com [2a00:1450:4007:807::2004] with 32 bytes of data:

现在我的问题是：这是否足以说我可以使用teredo从我的Lan外部访问？如果是的话......我的外部终点会让其他同行访问我吗？

这是我的c＃代码，用于收听teredo界面（如果出现问题，请更正我）：

UdpClient Client = new UdpClient(23456, AddressFamily.InterNetworkV6);
Client.AllowNatTraversal(true);
Client.Client.SetIPProtectionLevel(IPProtectionLevel.Unrestricted);
int counter = 0;
while(true)
{
    IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any,0);
    Byte[] receiveBytes = Client.Receive(ref RemoteIpEndPoint);
    string returnData = Encoding.ASCII.GetString(receiveBytes);
    Console.WriteLine(RemoteIpEndPoint.Address.ToString() + ":" + returnData.ToString() + " -" + counter);
    counter++;
}

这是我的代码，用于从对等方向我的电脑发送消息（这里我感到困惑）：

UdpClient client = new UdpClient(AddressFamily.InterNetworkV6);
byte[] Message = Encoding.ASCII.GetBytes("Hello my fiend");
//not sure what to put here .. but the following works and print results in the listener console from within my LAN 
client.Send(Message, Message.Length, new IPEndPoint(IPAddress.Parse("2001:0:53aa:64c:3057:6dae:4308:b55e"), 23456));
System.Threading.Thread.Sleep(1000);

如何使用teredo隧道从另一个对等体发送数据包？
