NSPM is a free and open-source network security application whose mission is to help system and network administrator to establish, monitor and manage security policies and firewall access rules. Relying on popular and widely used GNU/Linux components such as Iptables for rules establishment and PHP for front-end interface and web-based system interactions, it can be installed as a standalone application on most personal, SOHO or company servers without exotic dependencies or intensive configuration. Developed with security, accessibility and standards in mind, NSPM requires nothing more than a classic web browser and basic quite good networking knowledge to be part of any information system.
Used in a private production environment for three years, it currently goes though intensive testing before official stable community release.
If you are interested in the product, you are free to use it right now in its current relative stability and to send any feedback or bug report that may be useful to software improvement. I will be glad to hear any comment through forum, mail form or Google project page, thank you for your support and contribution.
