Apache Server VPN Setup: A Comprehensive Guide

Introduction

Welcome to our step-by-step guide on setting up an Apache Server VPN. Virtual Private Networks (VPNs) have become increasingly popular in recent years due to the growing need for secure, private internet browsing. A VPN allows you to encrypt your internet traffic and route it through a remote server, making it difficult for anyone to monitor or track your online activities. In this article, we will explore how to set up an Apache Server VPN, its advantages and disadvantages, and provide you with answers to frequently asked questions.

Before we dive into the details, let’s first understand what an Apache Server VPN is and how it works.

What is an Apache Server VPN?

Apache Server is a popular open-source web server software used to host websites and web applications. It can also be used to set up a virtual private network by configuring it to act as a VPN gateway. The Apache Server VPN creates a secure tunnel between two or more devices, allowing them to communicate securely over the internet.

How Does an Apache Server VPN Work?

When you connect to an Apache Server VPN, your device first establishes a secure connection with the server using encryption protocols such as OpenVPN or IPSec. Once the connection is established, all your internet traffic is routed through the server before it reaches its destination. The server encrypts your traffic and assigns it a new IP address, making it difficult for anyone to track your online activities.

Prerequisites for Apache Server VPN Setup

Before we begin with the setup process, there are a few prerequisites that you need to meet:

Prerequisites	Description
Apache Server	You should have a running Apache Server instance on your machine
VPN Client	You should have a VPN client installed on all devices that will connect to the VPN
Certificate Authority (CA)	You should have a CA to generate and sign SSL/TLS certificates for the VPN server and clients

Apache Server VPN Setup

Step 1: Install Required Packages

The first step is to install the required packages for the Apache Server VPN. You can do this by running the following command:

sudo apt-get install apache2 openssl libssl-dev libapache2-mod-auth-mysql libapache2-mod-php5 php5 php5-mysql php5-mcrypt php5-gd pptpd

Step 2: Configure PPTP Server

Next, we need to configure the PPTP server on the Apache Server. PPTP (Point-to-Point Tunneling Protocol) is a VPN protocol that allows you to tunnel your internet traffic through a remote server. To configure the PPTP server, follow these steps:

1. Open the /etc/pptpd.conf file
2. Add the following lines at the end of the file:
   localip 192.168.0.1
remoteip 192.168.0.100-200
   Note: Replace 192.168.0.1 with the IP address of your Apache Server and 192.168.0.100-200 with a range of IP addresses you want to assign to the VPN clients.
3. Open the /etc/ppp/pptpd-options file
4. Add the following lines at the end of the file:
   ms-dns 8.8.8.8
ms-dns 8.8.4.4
   Note: These are the Google DNS servers. You can replace them with the DNS servers of your choice.
5. Open the /etc/ppp/chap-secrets file
6. Add a line for each VPN client in the following format:
   <username> pptpd <password> *
   Note: Replace <username> and <password> with the username and password you want to use for the VPN clients.
7. Restart the PPTP server by running the following command:
   sudo /etc/init.d/pptpd restart

Step 3: Generate SSL/TLS Certificates

Now, we need to generate SSL/TLS certificates for the Apache Server and clients. SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a protocol used to secure internet communications. To generate the certificates, follow these steps:

1. Create a directory to store the certificates:
   sudo mkdir /etc/openvpn/ssl
2. Generate the CA certificate:
   sudo openssl req -new -x509 -days 365 -keyout /etc/openvpn/ssl/ca.key -out /etc/openvpn/ssl/ca.crt
   Note: Follow the prompts to enter the required information.
3. Generate the server certificate:
   sudo openssl req -new -nodes -keyout /etc/openvpn/ssl/server.key -out /etc/openvpn/ssl/server.csr
   Note: Follow the prompts to enter the required information.
4. Sign the server certificate:
   sudo openssl x509 -req -days 365 -in /etc/openvpn/ssl/server.csr -CA /etc/openvpn/ssl/ca.crt -CAkey /etc/openvpn/ssl/ca.key -set_serial 01 -out /etc/openvpn/ssl/server.crt
5. Generate the client certificate:
   sudo openssl req -new -nodes -keyout /etc/openvpn/ssl/client.key -out /etc/openvpn/ssl/client.csr
   Note: Follow the prompts to enter the required information.
6. Sign the client certificate:
   sudo openssl x509 -req -days 365 -in /etc/openvpn/ssl/client.csr -CA /etc/openvpn/ssl/ca.crt -CAkey /etc/openvpn/ssl/ca.key -set_serial 01 -out /etc/openvpn/ssl/client.crt
7. Copy the client certificates to the client devices

Step 4: Configure Apache Server VPN

Finally, we need to configure the Apache Server VPN. To do this, follow these steps:

1. Open the /etc/openvpn/server.conf file
2. Add the following lines at the end of the file:
   ca /etc/openvpn/ssl/ca.crt
cert /etc/openvpn/ssl/server.crt
key /etc/openvpn/ssl/server.key
dh /etc/openvpn/ssl/dh2048.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"
keepalive 10 120
comp-lzo
persist-key
persist-tun
3. Copy the /usr/share/doc/openvpn/examples/sample-config-files/client.conf file to the client devices
4. Modify the client configuration file and add the following lines:
   ca /etc/openvpn/ssl/ca.crt
cert /etc/openvpn/ssl/client.crt
key /etc/openvpn/ssl/client.key
remote <apache_server_ip> 1194
   Note: Replace <apache_server_ip> with the IP address of your Apache Server.
5. Connect the client devices to the VPN by running the following command:
   sudo openvpn --config /path/to/client.conf
