PC 无法路由到 Hyper-V 虚拟机，反之亦然
  • 地位
  1. 我的电脑有一个 Hyper-V VM 和一个 WSL 实例，它们的 IP 地址分别为192.168.254.30和192.168.254.20。
  2. 目标是建立从 WSL 到 Hyper-V VM 的 TCP 连接，但 PC 无法路由到 VM。

奇怪的是， 中未使用的地址192.168.254.0/24被路由到192.168.254.100。

如果我将 Hyper-V VM 的 IP 地址更改为此192.168.254.50，PC 就会开始192.168.254.50通过此路由172.25.18.2，即到互联网的路由。我必须在 VM 中执行某些操作吗？
