Setting up a (Point-to-Point Tunneling Protocol) PPTP server on Ubuntu, Linux, or CentOS involves several steps. Point to Point Transfer Protocol is a widely used virtual private network protocol that allows secure communication between remote users and a private network. Below is a comprehensive guide on how to set up a Point to Point Transfer Protocol server on Ubuntu, Linux, or CentOS.

PPTP Server On Ubuntu Linux and CenOS

Here are some of the reasons why you should consider using PPTP server on Ubuntu Linux and CentOS.

• Fast Connection Speeds
• Easy Setup Process
• Extensive Device Compatibility

How To Setup PPTP Server On Ubuntu Linux and CentOS?

Step 1: Update Your System

Before installing any software, it’s essential to ensure your system is up-to-date. Open a terminal and run the following commands:

For Ubuntu/Debian:

bash

Copy code

sudo apt update

sudo apt upgrade

For CentOS:

bash

Copy code

sudo yum update

Step 2: Install PPTP Server Software

Next, you’ll need to install the PPTP server software. On Ubuntu/Debian, use the following command:

bash

Copy code

sudo apt install pptpd

On CentOS, you can use:

bash

Copy code

sudo yum install pptp

Step 3: Configure PPTP Server

After installing the PPTP server software, you need to configure it. Open the PPTP configuration file in a text editor:

bash

Copy code

sudo nano /etc/pptpd.conf

Add the following lines at the end of the file:

plaintext

Copy code

localip 192.168.1.1

remoteip 192.168.1.100-200

Replace the IP addresses with the desired values. The local ip is the IP address of your PPTP server, and the remote ip is the range of IP addresses assigned to the clients.

Step 4: Configure PPTP Options

Edit the PPTP options file:

bash

Copy code

sudo nano /etc/ppp/pptpd-options

Add the following lines:

plaintext

Copy code

ms-dns 8.8.8.8

ms-dns 8.8.4.4

These are Google’s public DNS servers. You can replace them with your preferred DNS servers.

Step 5: Configure Authentication

Create a username and password file for PPTP:

bash

Copy code

sudo nano /etc/ppp/chap-secrets

Add the following line for each user:

plaintext

Copy code

username * password *

Replace username and password with the desired values.

Step 6: Enable IP Forwarding

Enable IP forwarding by editing the sysctl.conf file:

bash

Copy code

sudo nano /etc/sysctl.conf

Uncomment the following line:

plaintext

Copy code

net.ipv4.ip_forward=1

Apply the changes:

bash

Copy code

sudo sysctl -p

Step 7: Configure Firewall Rules

If you have a firewall enabled, configure it to allow PPTP traffic. For example, on Ubuntu with UFW:

bash

Copy code

sudo ufw allow 1723/tcp

sudo ufw allow 47/udp

sudo ufw enable

On CentOS with firewalld:

bash

Copy code

sudo firewall-cmd –zone=public –add-port=1723/tcp –permanent

sudo firewall-cmd –zone=public –add-port=47/udp –permanent

sudo firewall-cmd –reload

Step 8: Restart Services

Restart the PPTP and networking services:

bash

Copy code

sudo systemctl restart pptpd

sudo systemctl restart networking

Step 9: Test the PPTP Connection

Now, you should be able to connect to your point to point transfer protocol server using a Point to Point Transfer Protocol virtual private network client. Ensure that your firewall allows traffic on port 1723 (Transfer Control Protocol) and protocol 47 (Generic Routing Encapsulation).

Congratulations! you have successfully set up a point to point transfer protocol server on your Ubuntu, Linux, or CentOS system. Keep in mind that point to point transfer protocol is considered insecure due to its vulnerabilities, and it is recommended to use more secure virtual private network protocols like Layer 2 Tunneling Protocols/IPsec or OpenVPN if possible.
