Unlock Ubuntu 20.04: Step-by-Step Guide to Change Default Gateway
Introduction
Ubuntu 20.04, known for its stability and user-friendliness, is one of the most popular Linux distributions. It comes with a range of network configurations that are essential for daily operations. One of these configurations is the default gateway, which plays a crucial role in directing network traffic to other networks. This guide will walk you through the steps to change the default gateway on Ubuntu 20.04.
Understanding the Gateway
Before diving into the steps, let's understand what a gateway is. A gateway is a network device that connects two separate networks, such as your local network and the internet. When your computer sends data to another network, it uses the default gateway to route the data packets.
Why Change the Default Gateway?
There are several reasons why you might want to change the default gateway on your Ubuntu 20.04 system:
- Better Network Performance: By changing the default gateway, you might achieve better network performance by using a different route.
- Security Reasons: Sometimes, changing the default gateway can improve network security.
- Troubleshooting: If your current default gateway is not working, you might need to change it to another one.

Step-by-Step Guide to Change Default Gateway
Step 1: Check Current Default Gateway
First, you need to check the current default gateway on your system. Open a terminal and run the following command:
ip route show
Look for the line that starts with "default" to find the current default gateway.
Step 2: Open the Network Configuration File
The default gateway is stored in the /etc/network/interfaces file for most Ubuntu systems. Open this file with a text editor:
sudo nano /etc/network/interfaces
Step 3: Edit the Default Gateway
In the interfaces file, you will find a section like this:
auto eth0
iface eth0 inet dhcp
Add the following lines to change the default gateway:
default-gateway <new_gateway_ip>
Replace <new_gateway_ip> with the IP address of the new gateway.
Step 4: Save and Close the File
After making the changes, save and close the file. If you used nano, press Ctrl+O to save and Ctrl+X to exit.
Step 5: Restart the Network Service
Now, you need to restart the network service for the changes to take effect. Run the following command:
sudo systemctl restart networking
Step 6: Verify the Changes
To verify that the changes have been applied successfully, run the ip route show command again and check if the default gateway has been updated.
