NetworkManager、OpenVPN 和 float

我正在尝试使用 OpenVPN 连接到工作网络。不幸的是，工作网络位于 NAT 后面，这意味着我必须使用浮动选项才能使其正常工作。

显然，NetworkManager 不支持浮动选项 --- 似乎没有办法在配置选项中指定它。

我不想失去 NetworkManager，因为它提供了一种非常方便的方式来连接随机无线网络；但我必须使用 OpenVPN。我曾尝试直接使用原始 OpenVPN 配置文件来使用 OpenVPN，这可以正确设置连接，但现在它与 NetworkManager 的交互很糟糕，因此 DNS 和路由等都乱了套。

有谁知道让 NetworkManager 支持浮动选项的方法吗？

根据Ubuntu 论坛主题网络管理器的 ppa 中已添加一个补丁，但不再提供。

但是，该页面列出了以下代码，您可以尝试一下。

要将此补丁应用到您当前的 network-manager-openvpn 插件的源，如下所示：

mkdir ~/build-tmp
cd ~/build-tmp
apt-get source network-manager-openvpn
cd ./network-manager-openvpn*
wget http://onemyndseye.doesntexist.com/onemyndseye-ppa/patches/nm-advoptions-float.patch -O ./debian/patches/nm-advoptions-float.patch
echo "nm-advoptions-float.patch" >>./debian/patches/series
sudo apt-get build-dep network-mananger-openvpn
sudo apt-get install libglade2-dev devscripts build-essential
sudo dpkg-buildpackage

祝你好运。
