1，检查是否开启PPP
#cat /dev/ppp cat: /dev/ppp: No such device or address //表示已经开启
2，安装ppp和iptables
#yum install ppp
3，安装pptp
# rpm -ivh ftp://ftp.icm.edu.pl/vol/rzm5/linux-fedora/linux/epel/6/i386/pptpd-1.4.0-3.el6.i686.rpm
4，配置pptp
去掉“#”使102,103行生效
# (Recommended) localip 192.168.0.1 remoteip ,192.168.0.245 # or #localip ,192.168.0.245 #remoteip ,192.168.1.245
更改dns
# vim /etc/ppp/options.pptpd
38 # Require MPPE 128-bit encryption 39 # (note that MPPE requires the use of MSCHAP-V2 during authentication) 40 #require-mppe-128 //注释掉
# If pppd is acting as a server for Microsoft Windows clients, this # option allows pppd to supply one or two DNS (Domain Name Server) # addresses to the clients. The first instance of this option # specifies the primary DNS address; the second instance (if given) # specifies the secondary DNS address. ms-dns 8.8.8.8 //更改为谷歌DNS ms-dns 8.8.4.4
5，添加vpn账号，密码
# vim /etc/ppp/chap-secrets # Secrets for authentication using CHAP # client server secret IP addresses 用户名 pptpd 密码 *
6，修改内核设置，使其支持转发
vim /etc/pptpd.confnet.ipv4.ip_forward = 1 #net.ipv4.tcp_syncookies = 1 //注释掉
7，配置iptables转发规则
iptables -t nat -A POSTROUTING -s -j SNAT --to-source "vpsIP"service iptables save
8，设置pptp和iptables开机自启动
#chkconfig pptpd on #chkconfig iptables on#service pptpd restart#service iptables restart
