It supports real-time IP filtering that can be changed through an external script while the program is running. Besides, static IP filters can be created within the program.


The software can be hidden in the system tray. UDP data can be divided into multiple addresses if desired. Interfaces can be linked through the MAC address.

The interface is simple. An area where you can see the ports mapped, manually or dynamically, a connection panel and another to create port profiles that we can execute, edit or delete at any time. The program will use your network configuration to locate our gateway, and, therefore, our Internet gateway. Not all routers are compatible, and in some compatible models, you will have to enable this compatibility. When the router restarts, it loses any UPnP configuration that you have made.

The configuration creation interface allows you to add multiple ports at once, as long as they go to the same local IP as a destination, in the form of individual ports or port ranges.

Once made the modifications in your profile or configuration you have to click on “use” for the changes to apply.
