我正在尝试从位于具有相同子网(也是192.168.1.0/24)的网络上的客户端将vpn打开到办公网络(192.168.1.0/24)。它是linux(ubuntu 9.10)服务器和Windows客户端。
我遵循了这个ubuntu openvpn社区文档指南,从我可以知道的基础连接正常。当然,我会收到很多有关ip地址冲突的错误/警告。
然后,我试图按照本指南中的“肮脏的NAT技巧来使VPN与也已在专用地址空间中编号的客户端一起使用”,但没有成功。虽然我对路由/伪装有理论上的了解,但我的实践经验相对较少,并且不确定出什么问题。
到目前为止,我已经到了客户端连接到服务器并被分配IP 10.22.8.10的地步。但是,我无法像文档中所示那样对服务器ip 10.22.8.1进行ping操作。
服务器配置基本相同引导1与修改脱离导向器2的,即设置“服务器桥10.22.8.1 255.255.255.0 10.22.8.10 10.22.8.120”和“推“路线10.22.0.0 255.255.0.0 10.22.8.1 ”。另外,我将tap接口配置命令添加到up.sh。
客户端配置与指南1相同。
服务器'ifconfig tap0'(编辑:抱歉,如果看起来很麻烦。在编辑此帖子的预览窗格中看起来不错)

客户端路由似乎正常(路由打印):

但是,当我尝试到达10.22.8.1时,它似乎仍然想跳出本地互联网连接:

有人可以向我建议我做错了什么吗(或者,如果有一种简单,更可行的方法来做我想做的事情-请注意,按照指南2中的解决方案#1,不能重命名这两个子网)

,您使用的不是XP,而是Windows Vista或7。您能告诉我,以便我创建适当的VM进行测试吗?
