#	Shorewall 1.4 -- Sample Interface File For Three Interfaces
#
# 	/etc/shorewall/interfaces
#
#	You must add an entry in this file for each network interface on your
#	firewall system.
#
# Columns are:
#
#	ZONE
#			Zone for this interface. Must match the short name
#			of a zone defined in /etc/shorewall/zones.
#
#			If the interface serves multiple zones that will be
#			defined in the /etc/shorewall/hosts file, you should
#			place "-" in this column.
#
#	INTERFACE
#			Name of interface. Each interface may be listed only
#			once in this file. You may NOT specify the name of
#			an alias (e.g., eth0:0) here; see
#			http://www.shorewall.net/FAQ.htm#faq18
#
#			DO NOT DEFINE THE LOOPBACK INTERFACE (lo) IN THIS FILE.
#
#	BROADCAST
#			The broadcast address for the subnetwork to which the
#			interface belongs. For P-T-P interfaces, this
#			column is left blank.If the interface has multiple
#			addresses on multiple subnets then list the broadcast
#			addresses as a comma-separated list.
#
#			If you use the special value "detect", the firewall
#			will detect the broadcast address for you. If you
#			select this option, the interface must be up before
#			the firewall is started, you must have iproute
#			installed and the interface must only be associated
#			with a single subnet.
#			
#			If you don't want to give a value for this column but
#			you want to enter a value in the OPTIONS column, enter
#			"-" in this column.
#
#	OPTIONS
#			A comma-separated list of options including the
#			following:
#
#		dhcp
#				Interface is managed by DHCP or used by
#				a DHCP server running on the firewall or
#				you have a static IP but are on a LAN
#				segment with lots of Laptop DHCP clients.
#		norfc1918
#				This interface should not receive
#				any packets whose source is in one
#				of the ranges reserved by RFC 1918
#				(i.e., private or "non-routable"
#				addresses. If packet mangling is
#				enabled in shorewall.conf, packets
#				whose destination addresses are
#				reserved by RFC 1918 are also rejected.
#		routefilter
#				Turn on kernel route filtering for this
#				interface (anti-spoofing measure). This
#				option can also be enabled globally in
#				the /etc/shorewall/shorewall.conf file.
#		dropunclean
#				Logs and drops mangled/invalid packets
#		logunclean
#				Logs mangled/invalid packets but does
#				not drop them.
#		blacklist
#				Check packets arriving on this interface
#				against the /etc/shorewall/blacklist
#				file.
#		maclist
#				Connection requests from this interface
#				are compared against the contents of
#				/etc/shorewall/maclist. If this option
#				is specified, the interface must be
#				an ethernet NIC and must be up before
#				Shorewall is started.
#		tcpflags
#				Packets arriving on this interface are
#				checked for certain illegal combinations
#				of TCP flags. Packets found to have
#				such a combination of flags are handled
#				according to the setting of
#				TCP_FLAGS_DISPOSITION after having been
#				logged according to the setting of
#				TCP_FLAGS_LOG_LEVEL.
#		proxyarp
#				Sets /proc/sys/net/ipv4/conf/<interface>/proxy_arp.
#				Do NOT use this option if you are
#				employing Proxy ARP through entries in
#				/etc/shorewall/proxyarp. This option is
#				intended soley for use with Proxy ARP
#				sub-networking as described at:
#				http://www.tldp.org/HOWTO/mini/Proxy-ARP-Subnet
#		netnotsyn	
#				TCP packets that don't have the SYN flag set and
#				which are not part of an established connection
#				will be accepted from this interface, even if
#				NEWNOTSYN=No has been specified in 
#				/etc/shorewall/shorewall.conf.
#
#				This option has no effect if NEWNOTSYN=Yes.
#
#		The order in which you list the options is not
#		significant but the list should have no embedded white
#		space.
#
#	Example 1:
#			Suppose you have eth0 connected to a DSL modem, 
#			eth1 connected to your local network and eth2
#			connected to your dmz. Assuming that your local
#			subnet is 192.168.1.0/24 and your dmz subnet is
#			192.168.2.0/24 . The eth0 interface gets
#			it's IP address via DHCP from subnet
#			206.191.149.192/27.
#
#			Your entries for this setup would look like:
#
#			#ZONE	INTERFACE	BROADCAST		OPTIONS
#			net	eth0		206.191.149.223		dhcp
#			local	eth1		192.168.1.255						
#			dmz	eth2		192.168.2.255		
#
#	Example 2:
#			The same configuration without specifying broadcast
#			addresses is:
#
#			#ZONE	INTERFACE	BROADCAST		OPTIONS
#			net	eth0		detect			dhcp
#			loc	eth1		detect			
#			dmz	eth2		detect
