Setting up Possible Route Traffic: Connecting Local PC (Running Windows 11) to AWS Lightsail Instance (Running Ubuntu LTS 20.04) using PuTTY's Port Forwarding
In this article, we will discuss how to establish a connection between a local Windows 11 PC and an AWS Lightsail instance running Ubuntu LTS 20.04 using PuTTY's port forwarding feature. We will cover the key concepts and provide detailed instructions on how to configure PuTTY for port forwarding. By the end of this article, you will be able to connect to your AWS Lightsail instance from your local Windows 11 PC using PuTTY.
Prerequisites
- AWS Lightsail instance running Ubuntu LTS 20.04
- PuTTY installed on your local Windows 11 PC
Configuring PuTTY for Port Forwarding
To configure PuTTY for port forwarding, follow these steps:
- Open PuTTY and enter the host name or IP address of your AWS Lightsail instance in the "Host Name (or IP address)" field.
- Under "Connection > SSH > Tunnels", enter the source port (e.g., 8080) in the "Source port" field and the destination (e.g., localhost:80) in the "Destination" field. Make sure to check the "Dynamic" and "Auto" options.
- Click the "Add" button to add the port forwarding configuration.
- Click the "Open" button to open an SSH connection to your AWS Lightsail instance.
Testing the Connection
To test the connection, open a web browser on your local Windows 11 PC and enter "localhost:8080" in the address bar. If the connection is successful, you should see the default web page for your AWS Lightsail instance.
Troubleshooting
If you are unable to connect, make sure that the source port and destination are correct. You may also need to check the security group rules for your AWS Lightsail instance to ensure that incoming traffic on the destination port is allowed.
