using this approach the following:
# ISDN subsystem startup
if [ "X${isdn_enable}" = X"YES" -a -f /etc/rc.isdn ]; then
. /etc/rc.isdn
fi
in /etc/rc.network needs to be moved to just before:
# Initialize IP filtering using ipfw
echo ""
/sbin/ipfw -q flush > /dev/null 2>&1
if [ $? = 0 ] ; then
Right?
