# Shorewall 1.4 -- Interfaces File
#
# /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
#
# You may specify wildcards here. For example, if you
# want to make an entry that applies to all PPP
# interfaces, use 'ppp+'.
#
# 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 black.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. USE OF THIS OPTION IS
# NOT RECOMMENDED. It will be removed in
# Shorewall 2.0.
# logunclean - Logs mangled/invalid packets but does
# not drop them. This option will be
# removed in Shorewall 2.0.
# . . 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
#
# newnotsyn - 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.
#
# routeback - If specified, indicates that Shorewall
# should include rules that allow filtering
# traffic arriving on this interface back
# out that same interface.
#
# arp_filter - If specified, this interface will only
# respond to ARP who-has requests for IP
# addresses configured on the interface.
# If not specified, the interface can
# respond to ARP who-has requests for
# IP addresses on any of the firewall's
# interface. The interface must be up
# when Shorewall is started.
#
# detectnets - Automatically taylors the zone named
# in the ZONE column to include only those
# hosts routed through the interface.
#
# WARNING: DO NOT SET THE detectnets OPTION ON YOUR
# INTERNET INTERFACE!
#
# 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 and
# eth1 connected to your local network and that your
# local subnet is 192.168.1.0/24. The interface gets
# it's IP address via DHCP from subnet
# 206.191.149.192/27. You have a DMZ with subnet
# 192.168.2.0/24 using eth2.
#
# Your entries for this setup would look like:
#
# 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:
#
# net eth0 detect dhcp
# loc eth1 detect
# dmz eth2 detect
#
# Example 3: You have a simple dial-in system with no ethernet
# connections.
#
# net ppp0 -
