linux 搭建pptp

1.安装pptp

安装四个组建

yum install ppp -y

yum install dkms -y

yum install -y ppp-devel

rpm -ivh pptpd-1.4.0-1.el6.x86_64.rpm

支持数据包转发

vim /etc/sysctl.conf

net.ipv4.ip_forward = 1

设置局域网ip段

vim /etc/pptpd.conf

localip 192.168.2.1
remoteip 192.168.2.234-238,192.168.2.245

设置dns服务地址

vim /etc/ppp/options.pptpd

ms-dns 8.8.8.8
ms-dns 8.8.4.4

添加登录帐号

vim /etc/ppp/chap-secrets

# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
name  pptpd   password   *

生效

sysctl -p

至此pptp服务安装完成，客服的可以连接，但还无法利用vpn上网，还要在防火墙中配置数据转发规则

2.配置路由

firewall-cmd --permanent --direct --add-rule ipv4 filter INPUT 0 -i eth0 -p tcp --dport 1723 -j ACCEPT 
firewall-cmd --permanent --direct --add-rule ipv4 filter INPUT 0 -p gre -j ACCEPT 
firewall-cmd --permanent --direct --add-rule ipv4 filter POSTROUTING 0 -t nat -o eth0 -j MASQUERADE
firewall-cmd --permanent --direct --add-rule ipv4 filter FORWARD 0 -i ppp+ -o eth0 -j ACCEPT 
firewall-cmd --permanent --direct --add-rule ipv4 filter FORWARD 0 -i eth0 -o ppp+ -j ACCEPT
firewall-cmd --reload
