IPFW(4) 						   BSD Kernel Interfaces Manual 						   IPFW(4)

NAME

     ipfw -- IP packet filter and traffic accounting

SYNOPSIS

     To compile ipfw into the kernel, place the following option in the kernel configuration file:

	   options IPFIREWALL

     Other kernel options related to ipfw which may also be useful are:

	   options IPFIREWALL_DEFAULT_TO_ACCEPT
	   options IPFIREWALL_FORWARD
	   options IPFIREWALL_VERBOSE
	   options IPFIREWALL_VERBOSE_LIMIT=100

     To load ipfw as a module at boot time, add the following line into the loader.conf(5) file:

	   ipfw_load="YES"

DESCRIPTION

     The ipfw system facility allows filtering, redirecting, and other operations on IP packets travelling through network interfaces.

     The default behavior of ipfw is to block all incoming and outgoing traffic.  This behavior can be modified, to allow all traffic through the
     ipfw firewall by default, by enabling the IPFIREWALL_DEFAULT_TO_ACCEPT kernel option.  This option may be useful when configuring ipfw for
     the first time.  If the default ipfw behavior is to allow everything, it is easier to cope with firewall-tuning mistakes which may acciden-
     tally block all traffic.

     To enable logging of packets passing through ipfw, enable the IPFIREWALL_VERBOSE kernel option.  The IPFIREWALL_VERBOSE_LIMIT option will
     prevent syslogd(8) from flooding system logs or causing local Denial of Service.  This option may be set to the number of packets which will
     be logged on a per-entry basis before the entry is rate-limited.

     Policy routing and transparent forwarding features of ipfw can be enabled by IPFIREWALL_FORWARD kernel option.

     The user interface for ipfw is implemented by the ipfw(8) utility, so please refer to the ipfw(8) manpage for a complete description of the
     ipfw capabilities and how to use it.
