This page is a description of the FreeBSD operating system in contrast to
other systems I am familiar with such as Linux.

Most of FreeBSD's bootstrap and configuration scripts are located in the
"/etc" directory in contrast to Linux having most configuration scripts
located in "/etc/rc.d/" and for RedHat "/etc/sysconfig/".

-----------------------------------------------------------------------------

Devices "/dev":

Ethernet:
	"/dev/ed0", "/dev/ed1"
Serial:
	"/dev/cuaa0", "/dev/cuaa1"
IDE Hard disks:
	"/dev/wd0", "/dev/wd1", etc..
CDROM:
	"/dev/acd0a"
Floppy:
	"/dev/fd0" or "/dev/da0"

To preserve or backup the MBR of disk0 to a floppy:
	dd if=/dev/ad0 of=/dev/fd0 bs=512 count=1
To restore the FreeBSD boot manager (boot0):
	boot0cfg -B ad0
-----------------------------------------------------------------------------

To enable IP Packet forwarding you'll need to edit the /etc/rc.conf file.
This file contains overrides of the defaults in /etc/defaults/rc.conf.

The default gateway setting is controlled by the line
    gateway_enable="NO"
in that file. To override it, add a line like
    gateway_enable="YES"
