1) Install the wide-dhcp from packages. 

2) 2) Rebuild kernel to add the berkeley packet filter (if needed)
	options	bpfilter	4

Then there are a couple of different ways to get it started. 

3a) Put dhcpc.sh in /usr/local/etc/rc.d:

#!/bin/sh

# Change to your interface
interface=ix0

killproc()
{
	pid=`ps -ax |egrep $1 |sed -e 's/^  *//' -e 's/ .*//'`
	[ "$pid" != "" ] && kill $pid
}

case "$1" in
'start')

	# Make sure the interface is configured
	ifconfig $interface >/dev/null

	# ensure that client exists
	if [ $? -eq 0 -f /usr/local/sbin/dhcpc ]; then

		# -d start in debug mode (seems to work better
		# -r update resolv.conf
		/usr/local/sbin/dhcpc -dr $interface
		echo -n ' dhcpc'
	fi
	;;

'stop')
	killproc dhcpc
	;;

*)
	echo "Usage: $0 start|stop"
	;;
esac


3b) Or use the rc.network method, buy putting your interface in rc.conf, blank:

network_interfaces="ix0 lo0"
ifconfig_lo0="inet 127.0.0.1"
ifconfig_ix0=

	and then create a start_if.ix0 file in /etc (Probably about the same 
as the start portion of the above script).

3b is probably the better choice, since it brings up the interface much
sooner in the boot process.
