# Shorewall 1.4 -- Sample Interface File For One Interface
|
|
#
|
|
# /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
|
|
#
|
|
# 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
|
|
# that 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
|
|
#
|
|
# Example 2:
|
|
# The same configuration without specifying broadcast
|
|
# addresses is:
|
|
#
|
|
# #ZONE INTERFACE BROADCAST OPTIONS
|
|
# net eth0 detect dhcp
|
|
#
|
|
# Example 3:
|
|
# You have a simple dial-in system with no ethernet
|
|
# connections.
|
|
# #ZONE INTERFACE BROADCAST OPTIONS
|
|
# net ppp0 -
