我将openvpn-2.0.beta7.tar.gz和lzo-1.08.tar.gz下载到/home

#cd /home

#tar zxvf lzo-1.08.tar.gz

#cd lzo-1.08.

#./comfigure

#make

#make install

#tar zxvf openvpn-2.0_beta7.tar.gz

#cd openvpn-2.0_beta7

#./configure --with-lzo-headers=/usr/local/include --with-lzo-lib=/usr/local/lib

#make

#make install

#mkdir /etc/openvpn

#cd /etc/openvpn

#openvpn --genkey --secret static.key

将static.key从office主机复制到home主机的/etc/openvpn目录中

office#scp static.key root@218.85.158.244:/etc/openvpn

office#cd /home/openvpn-2.0_beta7/sample-config-files

office#cp static-office.conf /etc/openvpn

office#cp firewall.sh /etc/openvpn

office#cp openvpn-startup.sh /etc/openvpn

office#cp office.up /etc/openvpn

修改static-office.conf ,firewall.sh ,openvpn-startup.sh,office.up

我们先来看office主机的这几个配置文件

static-office.conf配置如下：

dev tun0

remote 218.85.158.244 #为对端的公网ip

ifconfig 10.1.0.1 10.1.0.2 #为本端和对端的vpn ip地址

secret /etc/openvpn/static.key #密钥

port 5000

comp-lzo

ping 15

ping 15

ping-restart 45

ping-timer-rem

persist-tun

persist-key

verb 3

office主机的firewall.sh脚本如下：

#!/bin/bash

PRIVATE=192.168.1.0/24

LOOP=127.0.0.1
