我正在将 OpenVPN 2.1.1 与 Windows XP x86 SP3 和 Windows 7 x64 客户端连接到包含 OpenVPN 2.1-rc15 的 Endian Community 2.4.0 盒。
两者连接都很好，但无法从 Windows 7 访问绿色 LAN 上的资源，但适用于 XP。
因此：我可以通过 VPN ping 推送网络上的主机，但使用 Windows7 我只能 ping 防火墙绿色 IP 地址。
编辑：我已尝试route-method exe/route-delay 2技巧，但并未解决问题。
关于 Endian 配置的更多细节（尝试了 2.2 和 2.4，均失败）：
红色=192.168.100.25；192.168.71.25
绿色=176.16.41.1
橙色=176.16.141.1
它基本上作为 OpenVPN 服务器运行，在红色提供服务，在绿色提供访问。
在 Windows XP 上，我使用默认OpenVPN 2.1.1 安装，使用 OpenVPN GUI（包含在安装中），一切都很顺利。
在 Windows 7 x64 上，我运行相同的程序，但现在以管理员身份使用 OpenVPN GUI。
它只能 ping 绿色网关，但不能 ping 其他机器。

谁知道出了什么问题？
--杰伦
答案1
好吧，我也遇到了同样的问题。尝试了所有方法，例如启用文件共享、设置相同的工作组等。除了这个之外，没有其他办法：
我注意到设备管理器中有多个网络适配器。所有适配器均已隐藏，因此必须单击“查看”并启用隐藏设备。
它们全都命名为 ...4to6 适配器。当我移除所有这些适配器后，我的文件/打印机共享和与 XP 客户端的网络连接在重启后开始工作。如果这些适配器数量巨大，则必须将它们全部移除。可以使用适当的（32 位或 64 位版本）工具 DEVCON.EXE（它是 Windows 驱动程序工具包的一部分 - 下载详细信息：Windows 驱动程序工具包版本 7.1.0）来完成此操作。更多信息可在此处找到。DevCon 命令行实用程序可作为设备管理器的替代品。
我在这里找到了这个解决方案：http://ryanvictory.com/posts/automating-6to4-adapter-removal-in-windows/
答案2
我解决了我的问题：这是一个测试用例错误。
Windows XP 正在连接到物理 Endian 盒。Windows
7 x64 正在连接到虚拟 Endian 盒。
虚拟盒在 VMware ESX/ESXi 上运行，使用虚拟网络交换机。
我忘了启用混杂模式对于该开关。
启用该功能后问题得到解决。
