I have 2 virtual networks, say 10.116.10.xxx and 10.116.11.xxx. I have the following code to send a magic packet:

using System;
using System.Net;
using System.Net.Sockets;
using System.Globalization;

public class MagicPackets:UdpClient    
{
    public MagicPackets() : base()
    {
    }

    public void SetClientToBrodcastMode()    
    {
      if(this.Active)
       this.Client.SetSocketOption(SocketOptionLevel.Socket,
                                 SocketOptionName.Broadcast,0);
    }
}

public class Run
{
     public static void Main(string[] args)
     {
        Run.WakeFunction(args[0]);
     }

     private static void WakeFunction(string MAC_ADDRESS)   
     {
          MagicPackets client=new MagicPackets();
          client.Connect(new 
             IPAddress(0xffffffff),
             0x2fff);
          client.SetClientToBrodcastMode();
          int counter=0;
          byte[] bytes=new byte[1024];
         //first 6 bytes should be 0xFF
         for(int y=0;y<6;y++)
            bytes[counter++]=0xFF;
         //now repeate MAC 16 times
         for(int y=0;y<16;y++)
         {
             int i=0;
             for(int z=0;z<6;z++)
             {
                  bytes[counter++]= 
                      byte.Parse(MAC_ADDRESS.Substring(i,2),
                      NumberStyles.HexNumber);
                  i+=2;
             }
         }

         int reterned_value=client.Send(bytes,1024);
     }
}

The code works fine when run it from a computer on the same virtual network as the computer I want to wake, but doesn't work if the computer is on the other virtual network. Any ideas why and how to fix?

Thanks, Gaz

マジックパケットはレイヤー2パケットであるため、ルーター（レイヤー3）の境界を越えないでください。

直し方？送信機と受信機を同じブロードキャストドメインに配置します。この場合、同じ仮想ネットワーク上にあります。
