PPTPD VPN server installation and configuration

This howto describes the steps in how to setup a PPTP VPN on Centos, Fedora, Debian, and Ubuntu with basic RSA authentication.

Before the installation make sure to have your Yum repos updated with the Epel repos.

CentOS and Red Hat Enterprise Linux 5.x

CentOS and Red Hat Enterprise Linux 6.x

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm && sudo rpm -Uvh epel-release-6*.rpm

CentOS and Red Hat Enterprise Linux 7.x

Step 1. Install PPTPD

CentOS/RedHat 5:

yum install pptpd.x86_64 -y

CentOS/RedHat 6:

yum install pptpd.x86_64 -y

Fedora 20:

yum install pptpd.x86_64 -y


apt-get install pptpd

Step 2. Edit IP setttings in /etc/pptpd.conf

echo > /etc/pptpd.conf

paste the following content into the pptpd.conf file


#start of custom file
option /etc/ppp/options.pptpd
localip   # local vpn IP 
remoteip  # ip range for connections
listen 23.216.x.x # eth0 my example public IP and network interface
#end of custom file

Step 3. Add user account in/etc/ppp/chap-secrets (assign username and password)

vi /etc/ppp/chap-secrets

usernameForuser1 *  setpassword1here  *

usernameForuser2 *  setpassword2here  *

Step 4. Optional settings in /etc/ppp/options.pptpd

echo > /etc/ppp/options.pptpd

Paste the following to your options.pptp


#custom settings for a simple fast pptp server
name pptpd
# Require MPPE 128-bit encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)


Step 5. Enable network forwarding in /etc/sysctl.conf

vi /etc/sysctl.conf

net.ipv4.ip_forward = 1

use the following command to apply the change:

sysctl -p

Step 6. Configure firewall (don’t skip this step even if you have firewall disabled.)

# sudo nano /etc/rc.local
iptables -t nat -A POSTROUTING -s -o eth0 -j MASQUERADE
iptables -A FORWARD -p tcp –syn -s -j TCPMSS –set-mss 1356

Step 7. Start PPTP VPN server


service pptpd restart

/etc/init.d/pptpd restart-kill && /etc/init.d/pptpd start

Note: To avoid starting pptp on every reboot you can automated by running chkconfig pptp on


The log of the VPN server, by default, is combined with system log located at /var/log/messages.
