Windows上的VirtualBox,路由和VPN

标签: routing vpn virtualbox

我正在尝试使用我的Ubuntu笔记本电脑连接到内部客户端网络,但客户端使用Nortel的Contivity VPN,因此它仅适用于Windows。我的想法是使用VirtualBox和Windows XP Guest建立VPN连接,然后使用Windows XP作为路由器通过VPN路由来自我的Ubuntu主机的流量。

我将VirtualBox中的第一个适配器配置为NAT,以便轻松访问Internet。我将第二个适配器配置为“仅限主机”,因此我现在可以在Ubuntu主机上看到一个新的vboxnet0接口,在Windows Guest中看到第二个适配器,我使用静态IP配置了该接口。

我已经确认我可以将Ubuntu ping到Windows,将Windows ping到Ubuntu。

路由表如下所示:

192.168.56.2是连接到Ubuntu主机端192.168.56.1的第二个适配器。

现在,当我建立VPN连接时,路由表由Contivity更改,我无法再ping主机,主机无法ping客户端。以下是运行VPN的路由表:

通过查看路由表,我无法理解为什么我失去了ping 192.168.56.1的能力,所以我很感激一些帮助,或者有关如何进一步解决这个问题的想法。

答案 0 :(得分:1)

我正在使用类似的方法:

只要VPN软件没有关闭所有非vpn连接,这就有效。我知道(和使用)的唯一软件是 Cisco VPN连接器 - 也许Nortel也是如此。

为了便于设置和使用,我设置了一台带有大量别名网络接口和专用IP的Linux机器,并将这种别名ip直接重定向到vpn网络上的目标。可以这么说:我将VPN机器桥接到本地网络上的IP。
