AnalogX PortMapper is a lightweight, free utility designed to map a specific TCP or UDP port on your local computer to any IP address and port on another machine. It is commonly used for port forwarding, bypassing proxy restrictions, or limiting access to servers based on incoming IP addresses. Here is how to use it: 1. Installation and Launch Download the application from the AnalogX website.
Run the installer and launch the application. The interface is straightforward, typically showing a list of active mappings. 2. Setting Up a New Port Map
To map a port, you are essentially telling the program: “Listen to this local port, and send traffic to this specific destination.”
Add/Create a new map: Click on the option to create a new mapping rule.
Local Port: Enter the port number on your current machine that you want to listen on (e.g., 8080).
Remote Host: Enter the IP address or hostname of the target machine (e.g., 192.168.1.50).
Remote Port: Enter the port on the target machine you want to reach (e.g., 80).
Protocol: Choose between TCP or UDP based on the service you are mapping. 3. Configuring Security (Access Control) PortMapper allows you to restrict who can use the map:
You can set it to allow “Any Address” (default) or restrict it to specific IPs.
This is useful for ensuring only your specific IP address can connect to a sensitive server, reducing the risk of unauthorized access. 4. Running the Mapper Once configured, the mapping takes effect immediately.
The application works as a background tool, often used to bridge connections between internal network devices and external networks (like the internet), similar to setting up port forwarding on a router, but done directly on a computer. Common Use Cases
Proxy Access: If you are behind a proxy and want to access a remote Telnet or web server, you can map a local port to that remote server to bypass restrictions.
Web Server Security: Restrict access to a local web server to only specific incoming IP addresses.
Game Servers/IoT Devices: Redirect traffic from a specific port to a specific machine or device on your network. If you’d like, I can:
Help you decide whether to use TCP or UDP for a specific application.
Explain how to check which ports are currently in use on your computer.
Give you a step-by-step example for a specific scenario, like setting up a web server. Let me know what you’d like to dive into! Network Downloads : PortMapper /// AnalogX
