我正在使用 Vodafone 3G 调制解调器。我已禁用系统中的其他网络设备（以太网、wifi、wimax），并关闭了防火墙和防病毒软件。cisco vpn 客户端连接成功，但我仍然无法访问计算机 192.168.147.120（以及网络上的任何其他计算机）。
欢迎提出任何建议，因为我不知道该怎么做。

答案1
您的 Cisco VPN 适配器的子网掩码为 255.0.0.0 和 IP 地址为 10.53.127.204，而 3G 加密狗的子网掩码为 255.255.255.252 和 IP 地址为 10.229.227.77。
这两个子网之间存在一些重叠，可能会造成窗口混淆。
比如说，您需要通过 vpn 访问的所有设备都是 10.53.127.x 地址，那么可以考虑将 vpn 的掩码更改为 255.255.255.0，如果您需要通过 vpn 访问 10.53.xx，则可以将掩码更改为 255.255.0.0。
说实话，我不确定这是否真的是问题所在，但重叠子网不会有任何帮助。如果您不确定正确的子网，可以咨询您的网络管理员。
编辑：还注意到您的 vpn 没有默认网关。
另外，正如所提到的，192.168.xx 地址的路由看起来确实有点奇怪，尽管我记得手动设置路由，其中指定的网关实际上是我 VPN 端的 IP，以便对各种内容进行快速检查。如果您使用的是 win7，可能值得尝试更改这些路由，以便网关实际上是另一端的设备，但如果我没记错的话，这在 XP 上不起作用。
修改 2：VPN 的 IP 地址最后显示为（首选），而 DHCP 已关闭。这对我来说也不太正确。
