When prompted, enter the required information such as country, state, city, organization name, and email address. This information will be used to create the SSL certificate.
Obtaining an SSL Certificate
Once you have generated the CSR, the next step is to obtain an SSL certificate. There are several options for obtaining an SSL certificate, including using a free service such as Let’s Encrypt or purchasing a certificate from a trusted certificate authority.
If you decide to use Let’s Encrypt, you can obtain a free SSL certificate by running the following command in the terminal:
sudo apt-get install certbot
- Enter the following command to obtain a certificate:
sudo certbot certonly -standalone -d vpn.yourdomain.com
- Replace “vpn.yourdomain.com” with your server’s domain name or IP address.
- Follow the prompts to complete the certificate request process.
If you choose to purchase an SSL certificate from a trusted certificate authority, you will need to follow their specific instructions for obtaining a certificate.
Configuring the SSL Certificate on the Raspberry Pi
Once you have obtained an SSL certificate, the final step is to configure it on the Raspberry Pi. Copy the certificate files to the appropriate directories on the Raspberry Pi by running the following commands:
sudo cp /etc/letsencrypt/live/vpn.yourdomain.com/fullchain.pem /etc/openvpn/
sudo cp /etc/letsencrypt/live/vpn.yourdomain.com/privkey.pem /etc/openvpn/
Replace “vpn.yourdomain.com” with your server’s domain name or IP address.
Once the certificate files have been copied, modify the OpenVPN server configuration file by adding the following lines:
Save the file and restart the OpenVPN service by running the following command:
sudo systemctl restart openvpn
With the SSL certificate configured, your Raspberry Pi VPN is now equipped with an added layer of security.
Configuring Firewall and Port Forwarding
Configuring the firewall and setting up port forwarding are crucial steps to ensuring proper communication with your Raspberry Pi VPN. Let’s take a look at how to do it.
By default, the Raspberry Pi has basic firewall rules that allow all outgoing connections but block incoming connections. To allow incoming connections for the VPN, you need to add rules to the firewall.
To begin, open the terminal and enter the following command:
sudo ufw allow OpenSSH
This allows incoming connections for SSH, which is needed for remote access to your Raspberry Pi. Next, add rules to allow incoming connections for the VPN protocol you have chosen. For example, to allow OpenVPN traffic:
sudo ufw allow 1194/udp
Be sure to replace 1194/udp with the correct port and protocol for your VPN.
Once you have added the necessary firewall rules, enable the firewall:
sudo ufw enable
In addition to configuring the firewall, you also need to set up port forwarding on your router. This allows traffic from the internet to reach your Raspberry Pi VPN.
The specific steps for port forwarding vary depending on your router. However, the general process includes:
- Log in to your router’s web interface.
- Locate the port forwarding section.
- Add a new port forwarding rule for the port and protocol used by your Raspberry Pi VPN.
- Ensure the rule is active and save the changes.
Once port forwarding is set up, you should be able to establish a remote connection to your Raspberry Pi VPN from outside your home network.
Creating User Accounts and Authentication
After preparing your Raspberry Pi for SSL VPN, you will need to create user accounts to manage access to your VPN.
To create a new user account, log in to your Raspberry Pi terminal and type:
sudo adduser [username]
Make sure to replace [username] with the desired name for the new user.
You will be prompted to set a password for the new user. Make sure to choose a strong, unique password that is different from the one you use for your Raspberry Pi login.
Next, you will need to configure authentication for your VPN. There are several options to choose from, including:
- Password authentication
- Two-factor authentication
- Public key authentication
Password authentication is the simplest option, but it is less secure than other methods. Two-factor authentication provides an additional layer of security by requiring a second form of identification, such as a token or biometric scan. Public key authentication is the most secure option, but it requires more setup and configuration.
To enable password authentication, open the OpenVPN server configuration file:
sudo nano /etc/openvpn/server.conf
Find the line that says “auth-user-pass” and uncomment it by removing the “;” at the beginning of the line. Save and close the file.
To enable two-factor authentication, you will need to install and configure a second-factor authentication tool, such as Google Authenticator or Authy. Consult the documentation for your chosen tool for instructions on how to set it up.
To enable public key authentication, you will need to generate a public/private key pair and configure your VPN server to use it. Consult the documentation for your VPN client and server software for instructions on how to set up public key authentication.
