我在Windows 10上，我使用Shrew软VPN连接到两个VPN服务器。我能够同时连接到两者。ipconfig将显示两个具有预期IP的虚拟适配器。在尝试调试与其中一个VPN服务器断续连接的问题时，我卸载并重新安装了Shrew软VPN。现在我无法同时连接到多个VPN服务器。

如果在已连接到第一个连接时启动第二个连接，则虚拟适配器将显示，但处于断开连接状态(媒体断开连接)。如果从第一个连接断开连接，则ipconfig将显示虚拟适配器，但现在它已连接并具有预期的IP。

我不知道我改变了什么；我所做的只是重新安装客户端。有人见过这个问题吗？或者有一种方法来调试这个问题--有什么我应该研究的吗？

更新

我已经验证了思科AnyConnect网络访问管理器(它是与思科AnyConnect安全移动客户端一起提供的)负责的；它被设计成一次只允许一个连接。当它看到第二个隧道正在建造时，它会介入并切断它。

在连接时，您可以从日志(使用Get-EventLog -LogName "Cisco AnyConnect Network Access Manager")中看到这一点。这里有一些相关的条目。在建立第一条隧道时，一切正常进行：

我想出了办法。解决方案是使用nvspbind并禁用虚拟适配器上的思科AnyConnect网络访问管理器筛选器。您需要从admin PowerShell提示符中运行nvspbind。

首先，您需要识别虚拟适配器的名称。我使用以下命令.\nvspbind.exe | Select-String -Pattern "Shrew Soft Virtual Adapter" -Context 0,1完成了这一操作。在我的机器上我有Local Area Connection* 10和Local Area Connection* 12。

然后，我禁用了Cisco NAM过滤器如下：

  • .\nvspbind.exe /d "Local Area Connection* 10" csco_acnamfd
  • .\nvspbind.exe /d "Local Area Connection* 12" csco_acnamfd

可以通过运行不带任何参数的nvspbind并滚动直到找到连接来验证是否禁用了筛选器。您应该看到如下所示：
