DAXFi is a Python script that helps configure several different kinds of firewalls in a consistent way. It can run as daemon to adapt its behavior to external conditions; rules can be described with XML files, XML strings, or generated directly by the code; the program can be configured and extended with a sort of plug-ins written in Python. It comes with a Python package, useful to build other applications aimed to manipulate different firewalls in a uniform way (some example programs are included).
