DNX Firewall is an optimized/high performance collection of applications or services to convert a standard linux system into a zone based next generation firewall.
All software is designed to run in conjunction with eachother, but with a modular design certain aspects can be completely removed with little effort. The primary security modules have DIRECT/INLINE control over all connections, streams, messages, that goes through the system.
