How to Change NAT Type on Your Android Mobile Hotspot: A Comprehensive Guide

Introduction

When using your Android device as a mobile hotspot, you may have encountered issues with the NAT (Network Address Translation) type, which affects your online gaming experience or the ability to connect with other devices. Changing the NAT type can help resolve these issues and improve your connectivity. In this comprehensive guide, we will discuss how to change the NAT type on your Android mobile hotspot and explore various methods that can be used to achieve this.

Understanding NAT Types

Before we dive into changing the NAT type, it's essential to understand what NAT is and the different NAT types available. NAT is a process that allows multiple devices to share a single public IP address. It helps to conserve the limited IPv4 address space and provides a basic level of security by hiding private network addresses from the public internet.

There are three main NAT types:

1. Open NAT (Type 1): This is the most desirable NAT type as it allows for the best connectivity, enabling your device to connect with any other device regardless of its NAT type. It is mostly found in wired connections and is ideal for online gaming and other online activities.

2. Moderate NAT (Type 2): This NAT type is more restrictive, allowing connections only with devices that have Open or Moderate NAT types. It can cause issues in some online gaming scenarios where you need to connect with devices that have a Strict NAT type.

3. Strict NAT (Type 3): This is the most restrictive NAT type, allowing connections only with devices that have an Open NAT type. It can cause significant connectivity issues, especially in online gaming, and is generally undesirable.

Methods to Change NAT Type on Android Mobile Hotspot

Now that we have a basic understanding of NAT types, let's explore the various methods you can use to change the NAT type on your Android mobile hotspot.

Method 1: Enable UPnP (Universal Plug and Play)

UPnP is a feature that allows devices to discover and communicate with each other on a network. It can help in changing the NAT type by automatically opening the necessary ports on your router. To enable UPnP on your Android device, follow these steps:

1. Go to Settings> Wireless & Networks> More> Tethering & portable hotspot.

2. Tap on Set up Wi-Fi hotspot.

3. Scroll down to the Advanced optionssection and tap on UPnP.

4. Toggle the switch to enable UPnP and tap Save.

After enabling UPnP, restart your mobile hotspot and check if the NAT type has changed.

Method 2: Use a VPN (Virtual Private Network)

A VPN can help change the NAT type by routing your internet traffic through a different network, which may have a more desirable NAT type. To use a VPN on your Android device, follow these steps:

1. Download and install a reputable VPN app from the Google Play Store.

2. Launch the VPN app and sign in or create an account.

3. Choose a server location and connect to the VPN.

4. Once connected, enable your mobile hotspot and check if the NAT type has changed.

Keep in mind that using a VPN may affect your internet speed, so choose a server location close to your actual location for the best performance.

Method 3: Configure Port Forwarding

Port forwarding is a technique that allows you to redirect specific network traffic to a particular device on your network. By configuring port forwarding, you can change the NAT type on your Android mobile hotspot. To do this, you will need access to your router's settings. Follow these steps:

1. Identify the IP address of your Android device by going to Settings> About phone> Status> IP address.

2. Access your router's settings by entering its IP address in a web browser (usually 192.168.0.1 or 192.168.1.1).

3. Log in to your router using the admin username and password (usually found on the router or in its documentation).

4. Locate the port forwarding settings (usually under "Advanced settings" or "Port forwarding").

5. Create a new port forwarding rule with the following information:

External port: The port number used by the game or service you want to improve connectivity for.

Internal port: The same as the external port.

Protocol: TCP/UDP (or both, if available).

IP address: The IP address of your Android device.

6. Save the new rule and restart your router.

After configuring port forwarding, enable your mobile hotspot and check if the NAT type has changed.

Final Thoughts

Changing the NAT type on your Android mobile hotspot can help improve your connectivity and online gaming experience. By using the methods discussed in this guide, you can achieve a more desirable NAT type and enjoy smoother online interactions. Remember that each method has its pros and cons, so choose the one that best suits your needs and preferences.
