- Changed <application>IPFW</application> to just IPFW since we're talking about the kernel functionality and not the command itself. Instances of "IPFW" in the handbook will be references to the kernel functionality, and <application/command>ipfw</> will be in reference to the command itself.
- Added note to inform readers that "^D" mean to use control-d, as well as "^C" mean control-c (wrapped in keycaps of course).
