To create a port mapping, click on the Create button from the Port mapping presets area and an “Edit Port Mapping Preset” window will appear. Not only does PortMapper allow you to view forwarded ports, you can also add or remove port mappings.

Simply run UPnP PortMapper and click the Connect button which will start searching for routers in your network, connect to it and get all the port mappings. UPnP PortMapper is a Java application that can run on Windows, Linux and Mac OS X as long as you have Java installed. If the application does not show the status of the port mapping, you can use a free and portable software called UPnP PortMapper. In this article we’ll show you how to add or check port forwarding in your router using a software and also to manage the port mappings of a UPnP router. For automatic port forwarding using UPnP to work, both the software and router must support this feature. Instead of connecting the router using a telnet client to view the text-based settings and manually typing commands to add a configuration, port forwarding is pretty much automatic these days thanks to Universal Plug and Play (UPnP). The solution is to forward the port which can be a daunting task for a lot of users as it needs the correct IP address, port number and transport protocol (TCP/UDP) or else it won’t work.įortunately the process of configuring port forwarding has gotten a lot easier through the years.

It is generally safer but also creates a huge problem which is a lot of applications that work over the Internet might stop working. One of the main differences in using a router is your computer’s connection to the router is hidden behind it and not directly exposed to the Internet unlike using a modem. Nowadays most people are connected to the Internet using a router instead of a modem.
