How Do You Expose a Local Web Server on the Internet?

Running a web server locally is a common practice during development. However, there may come a time when you need to expose your local web server to the internet so that others can access it. In this tutorial, we will explore different methods to achieve this.

1. Port Forwarding

If you have a router at home or in your office network, one way to expose your local web server is through port forwarding. Port forwarding allows incoming traffic on a specific port to be redirected to your local machine.

To enable port forwarding, follow these steps:

  1. Identify your local machine’s IP address: Open the command prompt (Windows) or terminal (macOS/Linux) and enter ipconfig (Windows) or ifconfig (macOS/Linux). Look for the IP address associated with your network adapter.
  2. Login to your router’s configuration page: Open your preferred web browser and enter the IP address of your router in the address bar. You will need to provide login credentials.
  3. Navigate to the port forwarding settings: The exact location may vary depending on your router’s make and model.

    Look for options like “Virtual Servers,” “Port Forwarding,” or “NAT.”

  4. Create a new port forwarding rule: Add a new rule by specifying the external port number, internal port number (usually the same as external), and internal IP address of your local machine.
  5. Save and apply changes: Once you have entered all the required information, save the settings and apply the changes. Your local web server should now be accessible from the internet using your router’s IP address and the specified port number.

2. Using a Reverse Proxy

An alternative method to expose your local web server is by using a reverse proxy. A reverse proxy acts as an intermediary between the client and your web server, forwarding requests to the appropriate destination.

To use a reverse proxy, follow these steps:

  1. Choose a reverse proxy software: There are several popular options like Apache, Nginx, and Caddy. Choose the one that suits your needs and install it on your local machine or a separate server.
  2. Configure the reverse proxy: Once installed, configure the reverse proxy software to listen on a specific port (e.g., 80 for HTTP or 443 for HTTPS) and forward requests to your local web server’s IP address and port.
  3. Update DNS records: If you have a domain name, update its DNS records to point to the public IP address of your machine or server where the reverse proxy is running.
  4. Test connectivity: After completing the configuration, test connectivity by accessing your domain name in a web browser. The reverse proxy should forward requests to your local web server and display the content on the internet.

3. Using Tunneling Services

If you don’t have access to router settings or prefer an easier setup process, tunneling services can help you expose your local web server without changing network configurations.

Tunneling services create secure connections between your local machine and their servers, allowing external access. One popular tool for tunneling is ngrok.

To use tunneling services like ngrok, follow these steps:

  1. Download and install the tunneling software: Visit the ngrok website and download the software for your operating system. Extract the files and run the executable.
  2. Expose your local server: Open a command prompt or terminal, navigate to the directory where ngrok is installed, and enter the command to expose your local web server.

    For example: ngrok http 80.

  3. Test connectivity: Once ngrok starts, it will provide a URL that maps to your local web server. Test accessibility by opening that URL in a web browser. Your local web server should now be accessible from anywhere.

By following these methods, you can expose your local web server on the internet for testing, collaboration, or other purposes. Choose the method that best suits your requirements and get ready to share your locally hosted applications with the world!
