If you've never tried to design your own firewall using Linux and IPtables, it can be a daunting and frustrating task. Michael and Scott Shinn have done a masterful job of explaining how IPtables interacts with the Linux networking subsystem, how packet filtering works, and how to make it work for you. This book explains in simple terms how to set about designing firewalls and isolating problems as part of the troubleshooting process to speed along debugging and repair efforts.
