Knetfilter This is a KDE 3.x gui to netfilter that is usable with kernel 2.4 and 2.5. Due to the latest Linux kernel developemnt, since version 3.1.0 Knetfilter needs at less Linux kernel 2.4.24 or newer to be fully functional. It is possible to manage a complete firewall for all standard and most of the non-standard operation just using Knetfilter. Anyway sometimes the command line could be usefull, expecially to set up MASQUERADE. Anyway I like to think that Knetfilter helps users also to better understand Linux netfilter, and possibly to learn more about how iptables work. You can download Knetfilter from: http://expansa.sns.it/knetfilter, or from any ftp.kde.org or sunsite.unc.edu mirror site (do not ask me the directory PATH). Remember to write me, venom@sns.it, to send me a feedback. For any suggestion, bug report or everything else related to the code, feel free to e-mail me, and I will take care about this. To install Knetfilter you have just to type: ./configure make clean make make install So, WHY do you waste your time? Just compile and enjoy. Luigi Genoni WARNING: Knetfilter should be stable, at less it is stable for me, but if I was not figuring some scenario for rules set up, (and probably I forgot a lot of them), then you could have problem. please, report all those problems, so I can fix it.
