WSL无外部连接（互联网）

Question

一段时间后，我的WSL（版本2）Ubuntu实例不再能够连接到Internet（或我的LAN）。在尝试了一些卸载VSWitches和WSL版本的内容之后，我现在使用了Microsoft Store安装的Ubuntu 22.04实例。

C:\Users\User>wsl -l -v
  NAME                   STATE           VERSION
* docker-desktop-data    Stopped         2
  Ubuntu-22.04           Stopped         2
  docker-desktop         Stopped         2

这是Ubuntu实例中的一些示例：

user@user-pc:~$ ping 1.1.1.1

因此，我有DNS解决方案并访问WSL主机，但没有Internet（我的LAN中的其他设备），

这里有一些主机网络网络的内容

如果您在具有管理员访问的公司网络上，请尝试此尝试，但要棘手的防火墙。

在powerShell

new -netFireWallrule -disPlayName“ wsl” - 方向入口-interfacealias“ vethernet（wsl

）” - action允许set set net -netfirewallprofile -profile -disabled public -disabledfacebableFaceAbledInterfacealiases
