9、设置开机自动运行服务。我们最后一步是将pptp和iptables设置为开机自动运行，这样就不需要每次重启服务器后手动启动服务了。当然你不需要自动启动服务的话可以忽略这一步。输入指令： #chkconfig pptpd on
PPTP 全称为 Point to Point Tunneling Protocol — 点到点隧道协议，是VPN协议中的一种。
安装相关软件
- yum install -y ppp iptables
- wget http://poptop.sourceforge.net/yum/stable/packages/pptpd-1.3.4-1.rhel5.1.i386.rpm
- rpm -ivh pptpd-1.3.4-1.rhel5.1.i386.rpm
配置文件/etc/ppp/options.pptpd
- mv /etc/ppp/options.pptpd /etc/ppp/options.pptpd.bak
- vi /etc/ppp/options.pptpd
输入以下内容：
- #相当于身份验证时的域，一定要和/etc/ppp/chap-secrets中的内容对应
- name pptpd
- #传输加密。ppp-2.4.2以上的版本只支持MPPE加密，内核模块为 ppp_mppe.o
- #拒绝pap,chap身份验证
- refuse-pap
- refuse-chap
- #拒绝mschap身份验证
- refuse-mschap
- #采用mschap-v2（Microsoft Challenge Handshake Authentication Protocol, Version 2）身份验证方式
- require-mschap-v2
- #在采用mschap-v2身份验证方式时要使用MPPE进行加密
- require-mppe-128
- #启动ARP代理
- proxyarp
- lock
- nobsdcomp
- novj
- novjccomp
- nologfd
- #分配给客户的DNS，这里用的是opendns
- ms-dns 208.67.222.222
- ms-dns 208.67.220.220
配置文件/etc/ppp/chap-secrets
- mv /etc/ppp/chap-secrets /etc/ppp/chap-secrets.bak
- vi /etc/ppp/chap-secrets
输入以下内容
- # Secrets for authentication using CHAP
- # client server secret IP addresses
- vi pptpd viyin.net *
用户名vi,密码viyin.net ，*表示任意ip
pptpd要和/etc/ppp/options.pptpd中的name 部分的pptpd匹配
配置文件/etc/pptpd.conf
- mv /etc/pptpd.conf /etc/pptpd.conf.bak
- vi /etc/pptpd.conf
输入以下内容：
- option /etc/ppp/options.pptpd
- logwtmp
- localip 10.100.1.1
- remoteip 10.100.1.20-50
为拨入VPN的用户动态分配IP
打开防火墙端口
1723端口和47端口打开，打开GRE协议
- /sbin/iptables -A INPUT -p tcp --dport 1723 -j ACCEPT
- /sbin/iptables -A INPUT -p tcp --dport 47 -j ACCEPT
- /sbin/iptables -A INPUT -p gre -j ACCEPT
- /sbin/iptables -A POSTROUTING -t nat -s 10.100.1.0/24 -o seth0 -j MASQUERADE
配置文件/etc/sysctl.conf
vi /etc/sysctl.conf
修改以下内容：
net.ipv4.ip_forward = 1
开启NAT转发功能
保存、退出后执行：
/sbin/sysctl -p
启动PPTP VPN 服务器端：
/sbin/service pptpd start
检查PPP是否支持MPPE，用以下命令检查PPP是否支持MPPE：
strings ‘/usr/sbin/pppd’ |grep -i mppe | wc –lines
果以上命令输出为“0”则表示不支持；输出为“30”或更大的数字就表示支持。
注意：
如果一直提示619或者800错误,查看日志
