Configuring the VPN Server

In this section, we'll walk you through configuring your VPN server, using a technical tone and providing step-by-step instructions with examples. We'll be using OpenVPN, a popular open-source VPN software, for this tutorial. OpenVPN is known for its security, reliability, and ease of use, making it an excellent choice for both beginners and advanced learners.

Step 1: Install OpenVPN

First, you'll need to install OpenVPN on your chosen server. For this example, we'll assume you're using a Linux-based system, such as Ubuntu.

Update your package list and install the necessary packages:
```
sudo apt-get update
sudo apt-get install openvpn easy-rsa
```

Step 2: Configure the Certificate Authority (CA)

The next step is to set up a Certificate Authority (CA) to issue and manage the SSL/TLS certificates needed for secure communication between your VPN server and clients.

Copy the Easy-RSA scripts to a new directory:
```
make-cadir ~/easy-rsa
cd ~/easy-rsa
```

Edit the vars file to configure your CA:

nano vars

Update the following fields with your information:

export KEY_COUNTRY="US"
export KEY_PROVINCE="CA"
export KEY_CITY="SanFrancisco"
export KEY_ORG="MyOrganization"
export KEY_EMAIL="me@example.com"
export KEY_OU="MyOrganizationalUnit"

Source the vars file and build the CA:
```
source vars
./clean-all
./build-ca
```

Step 3: Generate Server and Client Certificates

Now, you'll generate the server and client certificates needed for secure communication.

Build the server certificate and key:
```
./build-key-server server
```
Generate the Diffie-Hellman key exchange parameters:
```
./build-dh
```
Create a client certificate and key:
```
./build-key client1
```

Step 4: Configure the OpenVPN Server

With your certificates in place, you can now configure the OpenVPN server.

Copy the necessary files to the OpenVPN directory:

cd ~/easy-rsa/keys
sudo cp ca.crt ca.key server.crt server.key dh2048.pem /etc/openvpn

Create a new OpenVPN configuration file:

sudo nano /etc/openvpn/server.conf

Add the following configuration, replacing YOUR_PUBLIC_IP with your server's public IP address:

port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem
server 10.8.0.0 255.255.255.0
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 208.67.222.222"
push "dhcp-option DNS 208.67.220.220"
keepalive 10 120
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 3

Enable IP forwarding:
```
sudo nano /etc/sysctl.conf
```
Uncomment the following line:
```
net.ipv4.ip_forward=1
```
Apply the changes:
```
sudo sysctl -p
```
Start the OpenVPN server:
```
sudo service openvpn start
```

Your VPN server is now up and running! The next step is to configure the VPN clients on your devices, which we'll cover in the following section of this tutorial.
