0x00 前言

OpenVPN是一款跨平台的开源VPN软件，它利用虚拟网卡，以一种全新的方式实现了SSL VPN的功能，能够适应IP层之上的几乎所有应用。它使用TCP或UDP协议进行通信，相比于其它VPN，具有更好的NAT兼容性。

以下以腾讯云的Ubuntu 16.04.1 TLS 64位系统作为部署环境。
如无特别说明，以下所执行的命令都需要root权限。

0x01 创建证书

如果已经有证书，可以忽略本步操作。

安装easy-rsa

apt-get -y install easy-rsa

修改证书配置

cd /usr/share/easy-rsa

vi vars

修改以下变量的默认配置：

  1. export KEY_COUNTRY="US"
  2. export KEY_PROVINCE="CA"
  3. export KEY_CITY="SanFrancisco"
  4. export KEY_ORG="Fort-Funston"
  5. export KEY_EMAIL="me@myhost.mydomain"
  6. export KEY_OU="MyOrganizationalUnit"
  COPY

如：

  1. export KEY_COUNTRY="CN"
  2. export KEY_PROVINCE="GD"
  3. export KEY_CITY="Shenzhen"
  4. export KEY_ORG="drunkdream"
  5. export KEY_EMAIL="admin@drunkdream.com"
  6. export KEY_OU="drunkdream"
  COPY

将# export KEY_CN="CommonName"改为：export KEY_CN="server"

source ./vars

./clean-all

生成根证书

./build-ca

如果出现以下错误：

140695501473432:error:0E065068:configuration file routines:STR_COPY:variable has no value:conf_def.c:584:line 198

139878249313944:error:0E065068:configuration file routines:STR_COPY:variable has no value:conf_def.c:584:line 220

请注释掉198行和220行的内容：

subjectAltName=$ENV::KEY_ALTNAMES

一路回车，完成后，会在keys目录下生成ca.crt和ca.key。

生成服务器证书和密钥

./build-key-server server

遇到Sign the certificate? [y/n]以及1 out of 1 certificate requests certified, commit? [y/n]

请输入y，并回车；其它情况直接回车即可。

完成后，会在keys目录下生成server.crt、server.csr、server.key三个文件。

生成Diffie-Hellman密钥

./build-dh

该步操作耗时较长，请耐心等待。

完成后，会在keys目录下生成dh2048.pem文件。

生成客户端证书和密钥

./build-key client

与前面的步骤相同，在Sign the certificate和1 out of 1 certificate requests certified, commit?两处输入y并回车，其它地方直接回车即可。

完成后，会在keys目录下生成client.crt、client.csr、client.key三个文件。

0x02 安装OpenVPN并修改配置

apt-get -y install openvpn

OpenVPN的配置文件目录为：/etc/openvpn。

将之前生成的ca.crt、server.crt、server.key、dh2048.pem这四个文件拷贝到/etc/openvpn目录。

创建/etc/openvpn/server.conf文件，内容如下：

  COPY

server 192.168.1.0 255.255.255.0

这行可以根据期望分配的ip段进行相应修改。

0x03 开启iptables的NAT功能

开启ip数据包转发

修改/etc/sysctl.conf文件，去掉#net.ipv4.ip_forward=1前面的#，并保存

sysctl –p

这样就开启了ip数据包转发功能，从而支持在多个网卡间转发数据。

配置NAT转发规则

iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE

将所有来自VPN网段的数据都转发到eth0网卡，并修改源ip为eth0的网卡ip。

开启防火墙策略

iptables -A INPUT -p UDP –dport 1194 -j ACCEPT

此外，还要在腾讯云的云主机控制台中增加入站规则。

0x04 开启服务

systemctl start openvpn@server
systemctl enable openvpn@server

0x05 测试OpenVPN客户端

下载Windows版的OpenVPN安装程序，安装到系统中。

将前面生成的ca.crt、client.crt、client.key三个文件拷贝到电脑中，如：D:\openvpn目录。

将安装目录下sample-config目录中的client.ovpn文件拷贝到config目录下，并修改服务端ip和证书路径配置。

修改后的client.ovpn内容如下：

还有一种把证书插入到ovpn文件中的写法，这样可以不用额外提供三个证书文件。

去掉client.ovpn文件中的以下三行：

ca D:\openvpn\ca.crt
cert D:\openvpn\client.crt
key D:\openvpn\client.key

并在文件末尾加入以下内容：

  1. ###############################################################################
  2. # The certificate file of the destination VPN Server.
  3. # 
  4. # The CA certificate file is embedded in the inline format.
  5. # You can replace this CA contents if necessary.
  6. # Please note that if the server certificate is not a self-signed, you have to
  7. # specify the signer's root certificate (CA) here.
  9. <ca>

请根据具体服务器配置修改对应的内容。

打开OpenVPN GUI，选择刚才添加的配置项，进行连接。连接成功后，图标会从灰色变成绿色。
