CENTOS6.5 架设PPTPD 实现远程VPN

首先有个脚本: yum remove -y pptpd ppp iptables –flush POSTROUTING –table nat iptables –flush FORWARD rm -rf /etc/pptpd.conf rm -rf /etc/ppp yum -y install make libpcap iptables gcc-c++ logrotate tar cpio perl pam tcp_wrappers yum -y dkms-2.0.17.5-1.noarch.rpm yum -y kernel_ppp_mppe-1.0.2-3dkms.noarch.rpm rpm -qa kernel_ppp_mppe yum -y ppp-2.4.4-9.0.rhel5.i386.rpm yum -y pptpd-1.3.4-1.rhel5.1.i386.rpm mknod /dev/ppp c 108 0 echo 1 > /proc/sys/net/ipv4/ip_forward echo “mknod /dev/ppp c 108 0” >> /etc/rc.local echo “echo 1 > /proc/sys/net/ipv4/ip_forward” >> /etc/rc.local echo “localip 192.168.168.1” >> /etc/pptpd.conf echo “remoteip 192.168.168.12-254” >> /etc/pptpd.conf echo “ms-dns 8.8.8.8” >> /etc/ppp/options.pptpd echo “ms-dns 8.8.4.4” >> /etc/ppp/options.pptpd pass=`openssl rand 6 -base64` if [ “$1” != “” ] then pass=$1 fi echo “vpn pptpd ${pass} *” >> /etc/ppp/chap-secrets iptables -t nat -A POSTROUTING -s 192.168.168.0/24 -j SNAT –to-source `ifconfig  | grep ‘inet addr:’| grep -v ‘127.0.0.1’ | cut -d: -f2 | awk ‘NR==1 { print $1}’` iptables -A FORWARD -p tcp –syn -s 172.16.36.0/24 -j TCPMSS –set-mss 1356 service iptables save chkconfig iptables on chkconfig pptpd
