centos7 pptpd iptables
一.系統設置
關閉selinux
[[email protected] system]# cat /etc/selinux/config SELINUX=disabled
檢查是否支持
[[email protected] system]# modprobe ppp-compress-18 && echo yes yes
二.安裝pptp
[[email protected] system]# yum -y update [[email protected] system]#yum install pptpd pptp -y
設置:
[[email protected] system]# cat /etc/pptpd.conf|grep -v "#"|grep -v "^$" option /etc/ppp/options.pptpd logwtmp localip 192.168.36.1 remoteip 192.168.36.100-238 [[email protected] system]# cat /etc/ppp/options.pptpd |grep -v "#"|grep -v "^$" name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 ms-dns 8.8.8.8 ms-dns 8.8.4.4 proxyarp lock nobsdcomp novj novjccomp nologfd [[email protected] system]# cat /etc/ppp/chap-secrets # Secrets for authentication using CHAP # client server secret IP addresses test pptpd test1 *
如果撥號成功,服務器本機地址為:192.168.36.1
客戶端分配IP為:192.168.36.100-238.DNS為:8.8.8.8
以上都很簡單,走彎路是下面安裝iptables
三.設置防火墻
關閉firewalld,因為iptables nat寫法比firewalld方便
[[email protected] ~]# systemctl stop firewalld [[email protected] system]# systemctl disable firewalld
安裝iptables,需要註意的是,要安裝的是iptabels-services這個包,剛開始我是yum -y install iptables,死活找不到服務啟動.
[[email protected] system]# yum install iptables-services [[email protected] system]# systemctl enable iptables [[email protected] system]# systemctl start iptables
在其他規則的基礎上加上
[[email protected] system]# iptables -A INPUT -i eth0 -p tcp --dport 1723 -j ACCEPT [[email protected] system]# iptables -A INPUT -i eth0 -p tcp --dport 47 -j ACCEPT [[email protected] system]# iptables -I INPUT -p gre -j ACCEPT [[email protected] system]#iptables -t nat -A POSTROUTING -s 192.168.36.0/255.255.255.0 -j SNAT --to-source 103.*.*.*
其中103.*.*.*是你的服務器ip,最後一條是轉發
cento7沒有/etc/init.d/iptables save來保存規則,使用以下命令保存規則,不然機器重啟後iptables規則沒有,將規則保存到文件.機器重啟或者systemctl restart iptables 也會從文件中讀取配置
[[email protected] system]# iptables-save /etc/sysconfig/iptables
