硬件不会响应对方的ARP请求

我有两个硬件（embedded式设备），我已经设置为通过以太网以TCP / TCP方式进行通信。

networking的拓扑结构如下：

----- | S ||=|== Debug PC (w/ Wireshark) 192.168.10.41 | W ||=|== Hardware 1 TCP Client 192.168.10.42 | I ||=|== Hardware 2 TCP Server 192.168.10.40 | T | | C | | H | ----- 

硬件1尝试向服务器发送数据包Hardware 2时，首先发送一个ARP数据包，获取硬件2的MAC地址：

 No. Time Source Destination Protocol Length Info 157 11772.776136 Microchi_13:c3:6a Broadcast ARP 60 Who has 192.168.10.40? Tell 192.168.10.42 

但是，它没有收到来自服务器的回应，然后在一会儿之后，客户端MAC的服务器ARP：

• 在同一个主机上Ping同一个networking的接口不工作
• Linux：不存在主机的ARPcaching超时？
• 过期的ARPcaching条目对该DIP的stream量有什么影响，直到条目超出ARP表？
• 如何减lessLinux的盒子ARP响应？
• Permanant ARP条目变成未解决

 No. Time Source Destination Protocol Length Info 158 12183.800839 00:3f:2d:02:1a:35 Broadcast ARP 60 Who has 192.168.10.42? Tell 192.168.10.40 

其中也没有收到客户的回复。 我很困扰。

我知道服务器正确地回复，因为我用C＃编写了一个简单的TCP客户端，它可以从debuggingPC连接并发送数据包到服务器。

我不知道为什么我的硬件客户端无法通信。

感谢您的帮助提前。

ARP数据包的详细信息如果需要：

来自客户：
