Firstly, it is crucial to understand the importance of a firewall in protecting your VPN Server from unauthorized access and potential security threats. A firewall acts as a barrier between your server and the outside world, monitoring and controlling incoming and outgoing network traffic. By configuring your firewall properly, you can ensure that only authorized connections are allowed to access your VPN Server.
To begin, open the terminal on your Ubuntu Server and enter the following command to install the Uncomplicated Firewall (UFW):
“`
sudo apt-get install ufw
“`
Once the installation is complete, you can enable the firewall by running the following command:
“`
sudo ufw enable
“`
By default, UFW denies all incoming connections and allows all outgoing connections. However, since we want to use our server as a VPN Server, we need to allow incoming connections on specific ports. To do this, we will create rules to allow traffic on the necessary ports.
For example, if you are using OpenVPN, you will need to allow incoming connections on port 1194. To create a rule for this port, use the following command:
“`
sudo ufw allow 1194
“`
You can repeat this step for any additional ports required by your VPN Server.
Next, it is essential to restrict access to your VPN Server by allowing connections only from trusted IP addresses. This adds an extra layer of security by limiting access to your server. To do this, you can create rules to allow connections from specific IP addresses or IP ranges.
For instance, if you want to allow connections only from a specific IP address, you can use the following command:
“`
sudo ufw allow from
“`
Replace “ with the actual IP address you want to allow.
If you want to allow connections from an entire IP range, you can specify the range using CIDR notation. For example, to allow connections from the IP range 192.168.1.0/24, use the following command:
“`
sudo ufw allow from 192.168.1.0/24
“`
Remember to replace the IP range with your desired range.
Additionally, it is recommended to enable logging for your firewall to monitor any suspicious activity. By enabling logging, you can review the firewall logs and identify any potential security threats. To enable logging, run the following command:
“`
sudo ufw logging on
“`
With your firewall properly configured, you have taken significant steps towards securing your VPN Server. However, it is essential to regularly update your server’s software and apply security patches to ensure ongoing protection. Keeping your server up to date will help prevent any vulnerabilities that could be exploited by attackers.

You will be prompted to enter a password and additional information for the user. Once completed, the new user account will be created.
Next, we need to assign the appropriate permissions to the user account. By default, Ubuntu assigns the new user account with limited privileges. To grant administrative privileges, we need to add the user to the sudo group. Type the command “sudo usermod -aG sudo username” in the terminal, replacing “username” with the actual username.
Now that the user account is created and has administrative privileges, we can proceed to configure the VPN server. Open the terminal and type “sudo nano /etc/openvpn/server.conf” to edit the server configuration file. Look for the line that says “user nobody” and change it to “user username”, where “username” is the name of the user account you created earlier. Save the changes and exit the editor.
To ensure that the user account has the necessary permissions to access the VPN server, we need to modify the firewall rules. Type the command “sudo ufw allow OpenSSH” to allow SSH access, which is necessary for managing the server. Then, type “sudo ufw allow 1194/udp” to allow incoming VPN connections on the default port. Finally, enable the firewall by typing “sudo ufw enable”.
Now that the user account is set up and the necessary permissions are assigned, we can test the VPN connection. On a client device, install an OpenVPN client and import the server configuration file. Enter the username and password for the user account you created earlier. If the connection is successful, you have successfully set up your Ubuntu 18.04 Server as a VPN server.
To manage user accounts and permissions, you may need to modify or delete existing accounts. To modify an account, open the terminal and type “sudo usermod -aG groupname username”, replacing “groupname” with the desired group and “username” with the actual username. To delete an account, type “sudo deluser username”, replacing “username” with the actual username.
It is important to regularly review and update user accounts and permissions to maintain the security of your VPN server. By following these steps, you can effectively manage user accounts and assign appropriate permissions on your Ubuntu 18.04 Server VPN.
