I am trying to build a firewall of sorts by messing around with the ip tables in the kernel. Now this tweaked kernel( w/ some extra rules added on to it) serves as the backend of the firewall. For the frontend i thought of using kde/qt as i have been recommended those.
Since i am a newbie at this, i want to know that if i use either qt or kde for frontend, how would i be able to set up an interaction of the frontend with the kernel so that only those rules that are checked in the frontend are implemented in the kernel?
All suggestions/help would be tremendously appreciated!!
