Introduction
In this tutorial we will guide you to setup your own Poptop or PPTP VPN Server on CentOS 6. Please keep in mind that the PPTP MS-CHAP-v2 encryption is not considered very secure.
Prerequisites
You will need:
- A VPS Tiger server, order at Pricing
- Getting Started with VPS Tiger Tutorial
- SSH with root access.
Installing Wget
In minimal centos, you will need to install wget using yum.
yum -y install wget
You will get output similar to:
... Installed: wget.x86_64 0:1.12-10.el6 Complete!
Installing Poptop
We have created script to make the process easy and fast, you just have to run the script.
wget https://www.vpstiger.com/files/poptop/centos6/pptpd.sh
You will get output similar to:
... Saving to: “pptpd.sh” 100%[======================================>] 1,652 --.-K/s in 0s 2018-03-19 00:10:58 (39.5 MB/s) - “pptpd.sh” saved [1652/1652]
Run the script.
sh pptpd.sh
You will get output similar to:
... iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ] Starting pptpd: [ OK ] VPN service is installed, your VPN username is vpn, VPN password is IJYcY0gU
Enabling IP Forwarding
Enable IP forwarding.
sed -i 's/^net.ipv4.ip_forward.*/net.ipv4.ip_forward = 1/g' /etc/sysctl.conf
To verify run the following command.
sysctl -p
You will get output similar to:
net.ipv4.ip_forward = 1 ...
net.ipv4.ip_forward should have the value 1.
Firewall Routing
Configure routing with iptables.
iptables -t nat -I POSTROUTING -o eth0 -j MASQUERADE
Then save the configuration:
sudo iptables-save
Installing Nano
In minimal centos, you will need to install nano using yum.
yum -y install nano
You will get output similar to:
... Installed: nano-2.0.9-7.el6.x86_64 Complete!
PPTP Users
You can add, edit and remove users through chap-secrets file.
nano /etc/ppp/chap-secrets
You will get output similar to:
# Secrets for authentication using CHAP # client server secret IP addresses vpn pptpd IJYcY0gU *
vpn is username, while IJYcY0gU is password, you can edit it accordingly.
Once you completed the edit, save the file by pressing (CTRL + X) keyboard shortcut.
Restart the PPTP, so the new file is loaded.
/etc/init.d/pptpd restart
You will get output similar to:
Shutting down pptpd: [ OK ] Starting pptpd: [ OK ] Warning: a pptpd restart does not terminate existing connections, so new connections may be assigned the same IP address and cause unexpected results. Use restart-kill to destroy existing connections during a restart.
Conclusion
Your Poptop (PPTP) vpn server setup is complete. Now you can connect to your own Poptop (PPTP) VPN server from your PC or mobile device.
