操作系统Windows
服务器IP:192.168.88.123 VPN:192.168.89.1
客户端IP:192.168.78.3
客户端服务端单网卡,路由器做好端口映射
打开安装包进行安装,客户端跟服务器安装方式一样,都需要安装
接受下一步
下面两个选项默认不勾选,我们需要勾选不然安装完无法命令行制作证书操作
选择安装目录
安装完成
安装完成后系统会多出一张网卡TAP的 “本地连接2
要想客户端能够通过服务端上网需要调整服务端本地网卡共享
说明:
init-config # init-config 会把 vars.bat.sample 复制为 var.bat
vars # vars.bat 用来设置一些变量,主要就是配置文件中修改的那部分
clean-all # 会清掉 C: \Program File\OpenVPN\easy-rsa\keys 目录,再把 index.txt 和 serial 文件放进来。
build-ca # 生成根证书
build-dh.bat # 生成 dh1024.pem 文件,Server 使用 TLS(OpenSSL) 必须要有的文件
build-key-server server # 生成服务端密钥和证书
# server01 是自己定义的参数名,与上相应的就会生成 server01.key、server01.csr 和 server01.crt,也都是在 keys 目录里。
# 这一步像 build-dh.bat 一样有些东西要填写,之后就是该回答 y 的 y 一下,关键就一个:
# Common Name 必须填,且不能与执行 build-dh 时相同,否则会报:
# failed to update database
# TXT_DB error number 2
# 找不到 C:\Program Files\OpenVPN\easy-rsa\keys\*.old
# 三个文件 server01.key、server01.csr 和 server01.crt 也会生成,但文件 server01.crt 的大小是 0 字节无效的,就要重新再来,看到 Data Base Updated 才行。
# 要生成多个服务端的密钥和证书则继续 build-key-server server02 ......
build-key client #客户端生成密钥和证书
# build-ca和build-key-server一样要输入一堆东西,这里注意的是 Common Name 不能与执行 build-key-server 时输入的一样,与 build-ca 的 Common Name 一样我试过没什么关系,否则也是报:
# failed to update database
# TXT_DB error number 2
# 找不到 C:\Program Files\OpenVPN\easy-rsa\keys\*.old
# 要生成其他的客户端密钥和证书,可以继续 build-key client02 ......
..\bin\openvpn --genkey --secret keys\ta.key
# 生成 ta.key 文件
修改文件vars.bat.sample 在C:\Program Files\OpenVPN\easy-rsa 目录下用写字板打开 根据需求修改相关配置信息

生成后文件夹下产生如下文件:
创建服务端配置文件
把配置文件server.ovpn放到C:\Program Files\OpenVPN\config目录下
把C:\Program Files\OpenVPN\easy-rsa\keys目录下的
ca.crt、ca.key、server01.crt、server01.csr、server01.key、dh1024.pem、ta.key 复制到
C:\Program Files\OpenVPN\config目录下。
server.ovpn文件内容如下:

dev tun
ca ca.crt
cert server.crt
key server.key # This file should be kept secret

配置文件如下:
修改注册表:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters 将IPEnableRouter改为1
关闭防火墙或将8080端口加入到防火墙允许通过的端口中去
启动服务端
创建客户端配置文件:
把配置文件client.ovpn放到客户端机器的C:\Program Files\OpenVPN\config目录下,并且把服务器C:\Program Files\OpenVPN\easy-rsa\keys目录下的
client01.crt、client01.csr、client01.key、ca.key、ca.crt、ta.key 文件一起复制到
客户端C:\Program Files\OpenVPN\config目录下 (以上文件为服务端生成,客户端需要在服务端拷贝这7个文件过来)
client.ovpn配置文件如下:
client
dev tun
proto tcp
remote 服务端IP 8080
;remote my-server-2 8080
;remote-random

客户端连接后如下:
查看客户端获取的IP
查看客户端获取路由表
以下测试客户端到服务端的内网网络测试
以下是拨号前客户端电脑的出口IP
客户端电脑拨号后的出口IP已经变成了 服务端的出口IP
