# Shorewall 2.0 - /etc/shorewall/hosts
#
# THE ONLY TIME YOU NEED THIS FILE IS WHERE YOU HAVE MORE THAN
# ONE ZONE CONNECTED THROUGH A SINGLE INTERFACE.
#
# IF YOU DON'T HAVE THAT SITUATION THEN DON'T TOUCH THIS FILE.
#------------------------------------------------------------------------------
# IF YOU HAVE AN ENTRY FOR A ZONE AND INTERFACE IN
# /etc/shorewall/interfaces THEN DO NOT ADD ANY ENTRIES FOR THAT
# ZONE AND INTERFACE IN THIS FILE.
#------------------------------------------------------------------------------
# This file is used to define zones in terms of subnets and/or
# individual IP addresses. Most simple setups don't need to
# (should not) place anything in this file.
#
# The order of entries in this file is not significant in
# determining zone composition. Rather, the order that the zones
# are defined in /etc/shorewall/zones determines the order in
# which the records in this file are interpreted.
#
# ZONE - The name of a zone defined in /etc/shorewall/zones
#
# HOST(S) - The name of an interface defined in the
# /etc/shorewall/interfaces file followed by a colon (":") and
# a comma-separated list whose elements are either:
#
# a) The IP address of a host
# b) A subnetwork in the form
# <subnet-address>/<mask width>
# c) A physical port name; only allowed when the
# interface names a bridge created by the
# brctl addbr command. This port must not
# be defined in /etc/shorewall/interfaces and may
# optionally followed by a colon (":") and a
# host or network IP.
# See http://www.shorewall.net/Bridge.html for details.
#
# Examples:
#
# eth1:192.168.1.3
# eth2:192.168.2.0/24
# eth3:192.168.2.0/24,192.168.3.1
# br0:eth4
# br0:eth0:192.168.1.16/28
#
# OPTIONS - A comma-separated list of options. Currently-defined
# options are:
#
# maclist - Connection requests from these hosts
# 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.
#
# routeback - Shorewall should set up the infrastructure
# to pass packets from this/these
# address(es) back to themselves. This is
# necessary if hosts in this group use the
# services of a transparent proxy that is
# a member of the group or if DNAT is used
# to send requests originating from this
# group to a server in the group.
#
# norfc1918 - This option only makes sense for ports
# on a bridge.
#
# The port should not accept
# any packets whose source is in one
# of the ranges reserved by RFC 1918
# (i.e., private or "non-routable"
# addresses. If packet mangling or
# connection-tracking match is enabled in
# your kernel, packets whose destination
# addresses are reserved by RFC 1918 are
# also rejected.
#
# nobogons - This option only makes sense for ports
# on a bridge.
#
# This port should not accept
# any packets whose source is in one
# of the ranges reserved by IANA (this
# option does not cover those ranges
# reserved by RFC 1918 -- see
# 'norfc1918' above).
#
# blacklist - This option only makes sense for ports
# on a bridge.
#
# Check packets arriving on this port
# against the /etc/shorewall/blacklist
# file.
#
# tcpflags - Packets arriving from these hosts 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.
#
# nosmurfs - This option only makes sense for ports
# on a bridge.
#
# Filter packets for smurfs
# (packets with a broadcast
# address as the source).
#
# Smurfs will be optionally logged based
# on the setting of SMURF_LOG_LEVEL in
# shorewall.conf. After logging, the
# packets are dropped.
#
# newnotsyn - TCP packets that don't have the SYN
# flag set and which are not part of an
# established connection will be accepted
# from these hosts, even if
# NEWNOTSYN=No has been specified in
# /etc/shorewall/shorewall.conf.
#
# This option has no effect if
# NEWNOTSYN=Yes.
