How to Configure Port Mapping on Cloud Clusters Panel

Overview

This guide is intended for users who are running applications on our Linux VPS with the default Shared IP configuration and need to make those services accessible from the public internet.

By default, Shared IP Linux VPS instances run in a private internal network and do not have a dedicated public IP address. This means services running inside the VPS (such as a database, web service, or application server) cannot be accessed directly from the internet.

To enable external access, Cloud Clusters's control panel provides a gateway system that forwards traffic from a public IP and port to the internal IP and port of your VPS. In simple terms, the traffic flow works like this: Public IP : Public Port → VPS Internal IP : Internal Port

This process is called port mapping (also known as port forwarding). By configuring port mapping in the control panel, you can expose specific services running inside your VPS to the public internet.

Deployment Steps

Step 1: Deploy Your Application Inside the VPS

First, install and run the application inside your VPS and identify the internal service port it uses. For example, if you install MySQL, the default service port is: 3306

Step 2: Configure Port Mapping in the Control Panel

Once your application is running, you need to create a port mapping rule.

A. Open the Networking Page

  1. Go to Control Panel. Click the "Manage" button to go to your VPS Details page in the control panel.
    check the VPS destails
  2. Click the "Networking" button to configure port mapping. Then, click "Add Port Mapping".
    configure the port mapping

B. Create the Port Mapping Rule

In the pop-up window:

  • Inner Port: Enter the internal application port (for MySQL, this is 3306)
  • Remark: Enter a note for the rule (optional)

Click Confirm to add the mapping.
create the port mapping rule

C. Access Your Application

After the mapping is created successfully, a new rule will appear in the list. You will see:

  • Public IP
  • Public Port (automatically generated)
    access application
    You can now connect to your application using:
Public IP : Public Port

Your MySQL service is now accessible from the public internet.

Conclusion

Port mapping allows you to expose services running inside your VPS to the public internet by forwarding traffic from a public IP and port to the internal port of your application. Once configured, external users can access your services using the assigned public IP and port.
