Mac OS X 10.5 Leopard: About the Application Firewall
Mac OS X 10.5 Leopard includes a new technology called the Application Firewall. One of the basic purposes of a firewall is to control connections made to your computer from other computers on the network. In most firewall software, you must know the network ports and protocols an application uses to communicate, in order to control that application's network connections. Note: This article applies to the version of the Application Firewall included with Mac OS X 10.5.1 and later. Update to Mac OS X 10.5.1 or later if you have not yet done so. The Firewall in Leopard is an Application Firewall. This type of firewall allows you to control connections on a per-application basis, rather than a per-port basis. This makes it easier for less experienced users to gain the benefits of firewall protection and helps prevent undesirable applications from taking control of network ports that have been opened for legitimate applications. The Firewall applies to the Internet protocols most commonly used by applications, TCP and UDP. It does not affect AppleTalk. The Firewall may be set to block incoming ICMP "pings" by enabling Stealth Mode in the Advanced settings. Earlier ipfw technology is still accessible from the command line (in Terminal) and the Application Firewall does not overrule rules set with ipfw; if ipfw blocks an incoming packet, the Application Firewall will not process it. This article applies to the version of the Application Firewall included with Mac OS X 10.5.1 and later.

fwbuilder

fwbuilder(1)							 Firewall Builder						      fwbuilder(1)

NAME

       fwbuilder - Multiplatform firewall configuration tool

SYNOPSIS

       /usr/bin/fwbuilder [-ffile.fwb] [-d] [-h] [-ofile] [-Pobject_name] [-r] [-v]

DESCRIPTION

       fwbuilder is the Graphic User Interface (GUI) component of Firewall Builder.

       Firewall  Builder  consists  of	a  GUI	and  set of policy compilers for various firewall platforms. It helps users maintain a database of
       objects and allows policy editing using simple drag-and-drop operations. GUI generates firewall description in the form of XML file,  which
       compilers  then	interpret and generate platform-specific code. Several algorithms are provided for automated network objects discovery and
       bulk import of data. The GUI and policy compilers are completely independent, this provides for a consistent abstract model  and  the  same
       GUI for different firewall platforms.

       Firewall  Builder  supports  firewalls  based  on  iptables  (Linux kernel 2.4.x and 2.6.x, see fwb_ipt(1)), ipfilter (variety of platforms
       including *BSD, Solaris and others, see fwb_ipf(1)), pf (OpenBSD and FreeBSD, see fwb_pf(1)), ipfw (FreeBSD and others),  Cisco	PIX  (v6.x
       and 7.x) and Cisco IOS extended access lists.

OPTIONS

       -f FILE
	      Specify the name of the file to be loaded when program starts.

       -r     When this command line option is given in combination with -f file, the program automatically opens RCS head revision of the file if
	      file is in RCS. If file is not in RCS, this option does nothing and the file is opened as usual.

       -d     Turns on debug mode. Note that in this mode the program generates lots of output on standard error. This is used for debugging.

       -h     Prints brief help message

       -o file
	      Specify the name of the file for the print output, see option "-P".

       -P object_name
	      Print rules and objects for the firewall object "object_name" and immediately exit. The program does not go into	interactive  mode.
	      Print  output  will  be  placed in the file specified with "-o" option.  If file name is not given with option "-o", print output is
	      stored in the file "print.pdf" in the current directory.
