我在 Hyper-V 主机上有一个虚拟 Ubuntu 服务器（14.04）虚拟机，它有三块网卡
- eth0 桥接到外部网络
- eth1 和 eth2 连接到一个私有虚拟交换机
目的是让虚拟机使用 eth1 和 eth2 与自身进行通信，同时流量仍通过交换机发送 - 这样就可以转发/嗅探
我相信我已经为每个接口设置了正确的设置，并且也遵循了此处的帖子 -使用一个网关设置两个 IP 地址？
当我尝试从一个接口 ping 到另一个接口时，tcpdump 显示 ARP 请求到达另一个接口，但从未得到响应：
$ ping -b -I eth1 10.0.0.6
PING 10.0.0.6 (10.0.0.6) from 10.0.0.5 eth1: 56(84) bytes of data.

$ tcpdump -i eth2

21:27:20.666636 ARP, Request who-has 10.0.0.6 tell 10.0.0.5, length 28
...
我可以 ping 虚拟交换机上的其他设备...
更奇怪的是，我可以从另一个接口通过 SSH 连接到任一接口，但其流量不会显示在 tcpdump 上。
$ ssh -i eth1[电子邮件保护]
我所尝试做的事情有可能实现吗？
一些额外的信息：

不，这是不可能的：发往本地机器的数据包由本地机器处理，而不是转发。
