Installing Poptop (pptpd) VPN Server on CentOS 6
For roaming mobile clients PPTP (Point-to-Point Tunneling Protocol) is still the quickest way to get VPN connections to tunnel traffic over a secure link. Installation I always prefer installation via a yum repository as this will ensure patches are applied during regular system updates sudo rpm --import http://poptop.sourceforge.net/yum/RPM-GPG-KEY-PPTP sudo rpm -Uvh http://poptop.sourceforge.net/yum/stable/rhel6/pptp-release-current.noarch.rpm sudo yum install ppp pptpd -y Configuration Note: replace $USERNAME and $PASSWORD with actual values IP configuration echo "localip 192.168.0.1" >> /etc/pptpd.conf echo "remoteip 192.168.0.100-199" >> /etc/pptpd.conf DNS configuration echo "ms-dns 8.8.8.8" >> /etc/ppp/options.pptpd echo "ms-dns 4.2.2.1" >> /etc/ppp/options.pptpd Authentication configuration echo "$USERNAME pptpd $PASSWORD *" >> /etc/ppp/chap-secrets Firewall config service iptables start echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf sysctl -p echo "iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" >> /etc/rc.local iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE service iptables restart service iptables save chkconfig iptables on Start ppptd chkconfig pptpd on service pptpd start
