The Perfect Solution for Your Networking Needs
Greetings, readers! If you’re looking for an efficient way to manage your network and connectivity, you’ve come to the right place. In this article, we’ll discuss how to use Ubuntu Server as a router. Whether you’re a tech-savvy individual or a business owner, this guide will provide you with all the information you need to set up your own router using Ubuntu Server.
Introduction
Before we dive into the details, let’s first define what a router is and its purpose. A router is a device that connects multiple networks and directs internet traffic between them. Essentially, it acts as a traffic cop for all the data coming in and out of your network.
While you can easily buy a router off the shelf, building your own router using Ubuntu Server can be a cost-effective and customizable solution. Not only that, but it also provides greater security and control over your network.
What is Ubuntu Server?
Ubuntu Server is a free and open-source operating system that’s designed specifically for servers. It’s based on the popular Linux kernel and is known for its flexibility and scalability. Ubuntu Server is widely used by businesses, governments, and individuals around the world.

Hardware Requirements
Before setting up your Ubuntu Server as a router, you’ll need to ensure that you have the necessary hardware. Here are the basic requirements:
- At least two network cards
- A computer with a minimum of 2GB RAM
- At least 20GB of hard drive space
- A stable internet connection
Software Requirements
In addition to the hardware, you’ll also need to have the following software:
- Ubuntu Server 18.04 or later
- Netplan for network configuration
- IP forwarding enabled
- DHCP server
- DNS server
Setting up Ubuntu Server as a Router
Now, let’s move on to the steps for setting up your Ubuntu Server as a router:
Step 1: Install Ubuntu Server
The first step is to install Ubuntu Server on your computer. You can download the latest version of Ubuntu Server from the official website. The installation process is fairly straightforward, but you’ll need to ensure that you select the “Minimal installation” option.
Step 2: Configure Network Cards
Once you’ve installed Ubuntu Server, you’ll need to configure your network cards. You can do this by using Netplan, which is a YAML-based network configuration tool. By default, Netplan is installed on Ubuntu Server 18.04 and later.
Step 3: Enable IP Forwarding
In order for your Ubuntu Server to act as a router, you’ll need to enable IP forwarding. This can be done by modifying the “/etc/sysctl.conf” file and adding the following line:
net.ipv4.ip_forward=1
Step 4: Install DHCP Server
A DHCP server is necessary for assigning IP addresses to devices on your network. You can install a DHCP server on Ubuntu Server by using the following command:
sudo apt-get install isc-dhcp-server
Step 5: Install DNS Server
In addition to a DHCP server, you’ll also need a DNS server. A DNS server is responsible for translating domain names into IP addresses. You can install a DNS server on Ubuntu Server by using the following command:
sudo apt-get install bind9
Step 6: Configure Firewall
Lastly, you’ll need to configure a firewall to protect your network. Ubuntu Server comes with a built-in firewall called “ufw.” You can enable ufw and configure it by using the following command:
sudo ufw enable
