我无法192.168.0.155通过以太网访问家庭网络上的本地 Raspberry Pi 服务器 ( )，但我可以通过 wifi 完美地 ssh 到它。
我通过两个接口都可以正常连接互联网，并且在另一台 Macbook 上也出现相同的行为（可以通过 wifi 到达服务器，但不能通过以太网）。
所有以太网电缆都直接连接到我的家庭路由器（运行 DD-WRT），该路由器也充当无线接入点。
以下是我netstat -rn在 Macbook Pro ( ) 上使用以太网（通过 Thunderbolt 坞站）时的输出192.168.0.176：

我已经多次重置路由，重新启动笔记本电脑和路由器，并更改 Pi 服务器上的 IP，但问题仍然存在。
