UPnP_PortMapp0r

Add, remove and list port mappings (i.e. forwarding rules) to/from/of your UPnP-capable router from Windows.

System Requirements

This tool only runs on a Windows operating system (as it is just a wrapper around NATUPNPLib). It also needs a .NET Framework 4.0 compatible .NET platform installed (client profile suffices).

Usage

UPnP_PortMapp0r - by Sgt. Nukem, version: 0.1.3.7  
=================================================  

Usage: UPnP_PortMapp0r 'command' [parameters]

where 'command' can be:
  list    - lists all port mappings.
  add     - adds a port mapping, specify parameters       'port' 'protocol' 'mapped-address' [mapped-port]
  remove  - removes a port mapping, specifiy parameters   'port' 'protocol'

Exmaple:  > UPnP_PortMapp0r  add  443  TCP  192.168.1.200

Prerequisites

You will need a UPnP-capable router in your local subnet and enable dynamic adding of port mappings to programs.

Example Router configuration:

Manufacturer: AVM GmbH, Berlin, Germany Model: Fritz!Box 7320

Navigate to (german) Internet -> Freigaben -> Portfreigaben (english) Internet -> Sharing -> Port Sharing

You will need to check the option (german) [X] Änderungen der Sicherheitseinstellungen über UPnP gestatten" (english) [X] Allow changes to security settings via UPnP

Otherwise you will get strange COM exceptions like "HRESULT: 0x80040209".
