NS2Html is a tool created to convert the config file extracted from Netscreen devices into friendly HTML rulebases. It is a free tool developed by the need to collect data used for political firewall in the past administration. NS2Html project is developed under GPL. It is totally free, under the conditions of license. Feel free to use, develop or send to WHO need.As we could not apply these rulebases old on our firewall to actually see the rules, and analyzed, the only way to obtain information on these rulebases leaned on the config files generated by our NetScreen devices. And it was really boring, complicated and less productive.This way with NS2HTML, we can now generate HTML files from older versions of our rulebases. Besides, a backup of these HTML files can be stored for future use.As said, feel free to use, develop and other things allowed under the GPL.
