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了openvpn。

我一开始不小心下载了ubuntu 12.10，却没有注意到，我继续按照指南进行操作...

然后，我从这里进行了一些操作：推送“重定向网关def1” iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE

启用浏览。

OpenVPN功能全面。

我的意思是，我可以远程访问（访问内部服务）并从外部浏览时屏蔽我的IP。

然后我意识到我想要ubuntu 12.04，所以我在新安装中遵循相同的过程。

现在的问题是DNS无法解析。

我注意到下载openvpn时下载了我卸载的resolvconf，并尝试手动进行此操作。

这是我系统中的一些内容：

openvpn server.conf：

mode server
tls-server

local 192.168.1.101 ## ip/hostname of server
port 80 ## default openvpn port
proto udp

#bridging directive
dev tap0 ## If you need multiple tap devices, add them here
up "/etc/openvpn/up.sh br0 tap0 1500"
down "/etc/openvpn/down.sh br0 tap0"

persist-key
persist-tun

#certificates and encryption
ca ca.crt
cert server.crt
key server.key  # This file should be kept secret
dh dh1024.pem
tls-auth ta.key 0 # This file is secret

cipher BF-CBC        # Blowfish (default)

任何帮助，将不胜感激

这对我有用：http : //www.softwarepassion.com/solving-dns-problems-with-openvpn-on-ubuntu-box/

重要的步骤是将以下三行添加到客户端openvpn配置文件中：

script-security 2
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf

另外，请确保该resolvconf软件包已安装在客户端上，因为此脚本依赖于此脚本。

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

当您重新安装12.04时，您是否忘记了此步骤？
