使用OpenVPN的Ubuntu 12.04上的DNS问题
我按照本指南在家庭网络上设置openvpn。
我一开始不小心下载了ubuntu 12.10而没有注意到，我继续按照指南…
然后我从这里做了一些东西：推“redirect-gateway def1”iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE
启用浏览。
OpenVPNfunction齐全。
我的意思是，我能够远程访问（访问内部服务）并在从外部浏览时屏蔽我的IP。
然后我意识到我想要ubuntu 12.04，所以我在新的安装上遵循相同的过程。
现在的问题是DNS无法解决。
我注意到下载了openvpn，下载了我卸载的resolvconf，并试图手动进行此操作。
以下是我系统中的一些内容：
openvpn server.conf：

任何帮助，将不胜感激
这适用于我： http ： //www.softwarepassion.com/solving-dns-problems-with-openvpn-on-ubuntu-box/
重要的一步是在客户端openvpn配置文件中添加以下三行：
script-security 2 up /etc/openvpn/update-resolv-conf down /etc/openvpn/update-resolv-conf
还要确保客户端上安装了resolvconf软件包，因为此脚本依赖于它。
它适用于openvpn客户端服务或命令（ sudo openvpn youropenvpn.conf ）。
但是，Ubuntu网络管理器不适用于此配置。 到目前为止这是一个问题： https ： //bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1211110
当你重新安装12.04时你忘记了这一步吗？
