1、验证内核是否加载了MPPE模块：
modprobe ppp-compress-18 && echo MPPE is ok
2、安装所需的软件包：
yum -y install ppp
wget ftp://rpmfind.net/linux/epel/7/x86_64/p/pptpd-1.4.0-2.el7.x86_64.rpm
rpm -ivh pptpd-1.4.0-2.el7.x86_64.rpm
3、配置PPP和PPTP的配置文件：
grep ^[^#] /etc/ppp/options.pptpd
vi /etc/ppp/options.pptpd

logwtmp
localip 192.168.0.1
remoteip 192.168.0.207-217
|
4、打开内核的IP转发功能：
vi /etc/sysctl.conf
|
1
|
net.ipv4.ip_forward = 1
|
/sbin/sysctl -p
5、配置防火墙和NAT转发
|

|
yum install iptables-services
systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl enable iptables.service
systemctl start iptables.service
|
开启包转发：
|

3
|
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eno16777736 -j MASQUERADE
service iptables save
service iptables restart
|
开放端口和gre协议：
|
1

3
|
iptables -A INPUT -p tcp -m state --state NEW,RELATED,ESTABLISHED -m tcp --dport 1723 -j ACCEPT
iptables -A INPUT -p gre -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eno16777736 -j MASQUERADE
|
添加规则：

iptables -A INPUT -p gre -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 1723 -j ACCEPT
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -s 192.168.0.0/24 -o eno16777736 -j ACCEPT
iptables -A FORWARD -d 192.168.0.0/24 -i eno16777736 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eno16777736 -j MASQUERADE
service iptables save
|
启动和查看服务：
|

|
systemctl start pptpd
systemctl enable pptpd
systemctl status pptpd
|
6.查看pptpd服务进程和端口：
|

|
#ps -ef | grep pptpd
root 25100 1 0 14:19 ? 00:00:00 /usr/sbin/pptpd -f
root 25463 24275 0 14:52 pts/0 00:00:00 grep --color=auto pptpd
# netstat -nutap | grep pptpd
tcp 0 0 0.0.0.0:1723 0.0.0.0:* LISTEN 25100/pptpd
