PortMapper

PortMapper is a software tool developed in Java in order to aid individuals in configuring and managing port mapping on your router.

The upside of portable apps

You are not required to go through the installation process, as this utility is portable. This means that, unlike installers, it is not going to add new entries to the Windows registry and hard drive, without your permission, and it is not going to leave any kind of traces behind.
Another important aspect that you should take into consideration is that if you place the program files to an external data device, such as a USB flash drive, you make it possible to run PortMapper on any computer you have been granted access to.

Clean interface

The interface you are met with presents a pretty simple and clear-cut interface, as it is only built with a few buttons and several panes enabling you to view port mappings, logged messages and presets. As a result, all types of users can find their way around it, provided they have some working knowledge of networking.

Configure settings

This software app enables you to manage the port forwarding of a Universal Plug and Play enabled router in the local network. It lets you create an unlimited amount of port mapping profiles, along with information such as description, remote host, internal client and a port range.
Moreover, you can easily change the UPnP library and log level with the help of a drop-down menu and view logs in a separate pane.

Conclusion

To sum up, PortMapper is an efficient piece of software, dedicated to people interested in managing their port mappings. It is suitable to all user categories, it does not put a strain on the computer’s performance and our tests did not pick up on any errors or crashes.
