DesertFighter is a portable niche app to allow or block specific network connections.
DesertFighter aims to stop any unwanted connections between your computer and the network. Networking geeks might be disappointed at DesertFighter's simplicity, but that's just our opinion. That said, it does manage a few settings that most will appreciate.
The three categories provided have the potential to speed up your network, allow or block connections, and close all ports.
DesertFighter has three categories:
Block UDP (User Datagram Protocols) - Block or stop
Block distant Client - Block, stop, or exceptions
Block local client - Block or stop
DesertFighter isn't for everyone. It's free and portable and aimed to manage a handful of network connectivity options.
