fwb_ipfw - Policy compiler for ipfw

fwb_ipfw [-vVx] [-d wdir] [-o output.fw] [-i] -f data_file.xml object_name

fwb_ipfw is a firewall policy compiler component of Firewall Builder (see fwbuilder(1)). This compiler generates code for ipfw - a firewall and traffic shaper in FreeBSD (see ipfw(8)). Compiler reads objects definitions and firewall description from the data file specified with "-f" option and generates firewall configuration and activation script.

The generated file has a name that starts with the name of the firewall object, with an extension ".fw". It is a shell script that flushes current policy, then loads new filter and nat rules.

The data file and the name of the firewall objects must be specified on the command line. Other command line parameters are optional.

Specify the name of the data file to be processed.
Specify output file name
Specify working directory. Compiler creates firewall activation script in this directory. If this parameter is missing, then all files will be placed in the current working directory.
Be verbose: compiler prints diagnostic messages when it works.
Print version number and quit.
When this option is present, the last argument on the command line is supposed to be firewall object ID rather than its name
Generate debugging information while working. This option is intended for debugging only and may produce lots of cryptic messages.

Support for ipfw was added in version 1.0.10 of Firewall Builder
