+
+# 4) FTP is a firewall nightmare; if you allow "normal" FTP connections,
+#	you must be careful to block any TCP services that are listening
+#	on high ports; it's safer to require your FTP clients to use
+#	"passive" mode. 
+#
+#	Note this will also force clients on machines
+#	that use this one for NAT/IP Masquerading to use passive mode
+#	for connections that go through this server (e.g. from the
+#	internal network to public Internet machines
+#
+#	For more information about FTP, see the Bastille README.FTP doc
+#
+#FORCE_PASV_FTP="N"
+#FORCE_PASV_FTP="Y"					# SAFEST
+#
+FORCE_PASV_FTP="N"					# SAFEST
+
+
+# 5) Services to explicitly block. See FTP note above
+#	Note that ranges of ports are specified with colons, and you
+#	can specify an open range by using only one number, e.g.
+#	1024: means ports >= 1024 and :6000 means ports <= 6000
+#
+# TCP services on high ports that should be blocked if not forcing passive FTP
+# This should include X (6000:6010) and anything else revealed by 'netstat -an'
+#  (this does not matter unless you're not forcing "passive" FTP)
+#TCP_BLOCKED_SERVICES="6000:6020"
+#
+# UDP services to block: this should be UDP services on high ports.
+# Your only vulnerability from public interfaces are the DNS and
+# NTP servers/networks (those with 0.0.0.0 for DNS servers should
+# obviously be very careful here!)
+#UDP_BLOCKED_SERVICES="2049"
+#
+# types of ICMP packets to allow
+#ICMP_ALLOWED_TYPES="destination-unreachable"		# MINIMAL/SAFEST
+# the following allows you to ping/traceroute outbound
+#ICMP_ALLOWED_TYPES="destination-unreachable echo-reply time-exceeded"

+# Please make sure variable assignments are on single lines; do NOT
+# use the "\" continuation character (so Bastille can change the

+
+# 6) Source Address Verification helps prevent "IP Spoofing" attacks
+#
+ENABLE_SRC_ADDR_VERIFY="Y"				# SAFEST
+
+
+# 7) IP Masquerading / NAT. List your internal/masq'ed networks here
+#
+#	Also see item 4, FORCE_PASV_FTP, as that setting affects
+#	clients using IP Masquerading through this machine
+#
+# Set this variable if you're using IP Masq / NAT for a local network
+#IP_MASQ_NETWORK=""					# DISABLE/SAFEST
+#IP_MASQ_NETWORK="10.0.0.0/8"				# example
+#IP_MASQ_NETWORK="192.168.0.0/16"			# example
+#
+# Have lots of masq hosts? uncomment the following six lines 
+#  and list the hosts/networks in /etc/firewall-masqhosts
+#  the script assumes any address without a "/" netmask afterwards
+#  is an individual address (netmask /255.255.255.255):
+#if [ -f /etc/firewall-masqhosts ]; then
+#  echo "Reading list of masq hosts from /etc/firewall-masqhosts"
+#  # Read the file, but use 'awk' to strip comments
+#  # Note the sed bracket phrase includes a space and tab char
+#  IP_MASQ_NETWORK=`cat /etc/firewall-masqhosts | awk -F\# '/\// {print $1; next} /[0-9]/ {print $1"/32"}' |sed 's:[ 	]*::g'`
+#fi
+# 
+# Masq modules
+# NB: The script will prepend "ip_masq_" to each module name
+#IP_MASQ_MODULES="cuseeme ftp irc quake raudio vdolive"	# ALL (?)
+#IP_MASQ_MODULES="ftp raudio vdolive"			# RECOMMENDED
+#
+# Please make sure variable assignments are on single lines; do NOT
+# use the "\" continuation character (so Bastille can change the
+# values if it is run more than once)
+IP_MASQ_NETWORK="192.168.4.0/24"					# DISABLE/SAFEST
+IP_MASQ_MODULES=""			# RECOMMENDED
+
+
+# 8) How to react to disallowed packets
+# whether to "REJECT" or "DENY" disallowed packets; if you're running any
+# public services, you probably ought to use "REJECT"; if in serious stealth
+# mode, choose "DENY" so simple probes don't know if there's anything out there
+#	NOTE: disallowed ICMP packets are discarded with "DENY", as
+#		it would not make sense to "reject" the packet if you're
+#		trying to disallow ping/traceroute
+#
+REJECT_METHOD="DENY"
+
+
+# 9) DHCP
+#    In case your server needs to get a DHCP address from some other
+#    machine (e.g. cable modem)
+#DHCP_IFACES="eth0"			# example, to allow you to query on eth0
+#DHCP_IFACES=""				# DISABLED
+#
+# Please make sure variable assignments are on single lines; do NOT
+# use the "\" continuation character (so Bastille can change the
+# values if it is run more than once)
+DHCP_IFACES=""				# DISABLED
+
+
+# 10) more UDP fun. List IP addresses or network space of NTP servers
+#
+#NTP_SERVERS=""				# DISABLE NTP QUERIES / SAFEST
+#NTP_SERVERS="a.b.c.d/32 e.f.g.h/32"	# example, to allow querying 2 servers
+#
+# Please make sure variable assignments are on single lines; do NOT
+# use the "\" continuation character (so Bastille can change the
+# values if it is run more than once)
+NTP_SERVERS=""				# DISABLE NTP QUERIES / SAFEST
+
+
+# 11) more ICMP. Control the outbound ICMP to make yourself invisible to
+#     traceroute probes
+#
+#ICMP_OUTBOUND_DISABLED_TYPES="destination-unreachable time-exceeded"
+#
+# Please make sure variable assignments are on single lines; do NOT
+# use the "\" continuation character (so Bastille can change the
+# values if it is run more than once)
+ICMP_OUTBOUND_DISABLED_TYPES="destination-unreachable time-exceeded"
+
+
+# 12) Logging
+#	With this enabled, ipchains will log all blocked packets.
+#	         ** this could generate huge logs **
+#	This is primarily intended for the port mointoring system; 
+#	also note that you probably do not want to "AUDIT" any services
+#	that you are not allowing, as doing so would mean duplicate
+#	logging
+LOG_FAILURES="N"				# do not log blocked packets
+
+# 13) Block fragmented packets
+#       There's no good reason to allow these
+#ALLOW_FRAGMENTS="N"				# safest
+ALLOW_FRAGMENTS="Y"				# old behavior
+
+# 14) Prevent SMB broadcasts from leaking out NAT setup
+#	Windows machines will poll teh net with SMB broadcasts,
+#	basically advertising their existence. Most folks agree
+#	that this traffic should be dropped
+#DROP_SMB_NAT_BCAST="N"		# allow them (are you sure?)
+DROP_SMB_NAT_BCAST="Y"		# drop those packets
