UpnpRequester is a simple command-line based tool for opening & closing ports via Upnp.
Upnp requires java 15+ to run.

Functionality:

Commands:

• java -jar <Filename> remove <External IPV4 Port> - Removes the mapping for the given external IPV4 port for this device if it exist.

• java -jar <Filename> exists 25565 - Checks if the external IPV4 port exists or not.

Credit:

This project relies entirely on the fork of weupnp by fireDuck64. Almost all credit goes to fireDuck & the original project of weupnp. I've only made a simple command-line utility to interact with all the work they've put in.

Building:

To build this project yourself clone it from git, & run "maven package".
