#
# Shorewall version 3.0 - Rules File
#
# /etc/shorewall/rules
#
# Rules in this file govern connection establishment. Requests and
# responses are automatically allowed using connection tracking. For any
# particular (source,dest) pair of zones, the rules are evaluated in the
# order in which they appear in this file and the first match is the one
# that determines the disposition of the request.
#
# In most places where an IP address or subnet is allowed, you
# can preceed the address/subnet with "!" (e.g., !192.168.1.0/24) to
# indicate that the rule matches all addresses except the address/subnet
# given. Notice that no white space is permitted between "!" and the
# address/subnet.
#------------------------------------------------------------------------------
# WARNING: If you masquerade or use SNAT from a local system to the internet,
# you cannot use an ACCEPT rule to allow traffic from the internet to
# that system. You *must* use a DNAT rule instead.
#------------------------------------------------------------------------------
#
# The rules file is divided into sections. Each section is introduced by
# a "Section Header" which is a line beginning with SECTION followed by the
# section name.
#
# Sections are as follows and must appear in the order listed:
#
# ESTABLISHED Packets in the ESTABLISHED state are processed
# by rules in this section.
#
# The only ACTIONs allowed in this section are
# ACCEPT, DROP, REJECT, LOG and QUEUE
#
# There is an implicit ACCEPT rule inserted
# at the end of this section.
#
# RELATED Packets in the RELATED state are processed by
# rules in this section.
#
# The only ACTIONs allowed in this section are
# ACCEPT, DROP, REJECT, LOG and QUEUE
#
# There is an implicit ACCEPT rule inserted
# at the end of this section.
#
# NEW Packets in the NEW and INVALID states are
# processed by rules in this section.
#
# WARNING: If you specify FASTACCEPT=Yes in shorewall.conf then the
# ESTABLISHED and RELATED sections must be empty.
#
# Note: If you are not familiar with Netfilter to the point where you are
# comfortable with the differences between the various connection
# tracking states, then I suggest that you omit the ESTABLISHED and
# RELATED sections and place all of your rules in the NEW section.
#
# You may omit any section that you don't need. If no Section Headers appear
# in the file then all rules are assumed to be in the NEW section.
#
# Columns are:
#
# ACTION ACCEPT, DROP, REJECT, DNAT, DNAT-, REDIRECT, CONTINUE,
# LOG, QUEUE or an <action>.
#
# ACCEPT -- allow the connection request
# ACCEPT+ -- like ACCEPT but also excludes the
# connection from any subsequent
# DNAT[-] or REDIRECT[-] rules
# NONAT -- Excludes the connection from any
# subsequent DNAT[-] or REDIRECT[-]
# rules but doesn't generate a rule
# to accept the traffic.
# DROP -- ignore the request
# REJECT -- disallow the request and return an
# icmp-unreachable or an RST packet.
# DNAT -- Forward the request to another
# system (and optionally another
# port).
# DNAT- -- Advanced users only.
# Like DNAT but only generates the
# DNAT iptables rule and not
# the companion ACCEPT rule.
# SAME -- Similar to DNAT except that the
# port may not be remapped and when
# multiple server addresses are
# listed, all requests from a given
# remote system go to the same
# server.
# SAME- -- Advanced users only.
# Like SAME but only generates the
# NAT iptables rule and not
# the companion ACCEPT rule.
# REDIRECT -- Redirect the request to a local
# port on the firewall.
# REDIRECT-
# -- Advanced users only.
# Like REDIRET but only generates the
# REDIRECT iptables rule and not
# the companion ACCEPT rule.
#
# CONTINUE -- (For experts only). Do not process
# any of the following rules for this
# (source zone,destination zone). If
# The source and/or destination IP
# address falls into a zone defined
# later in /etc/shorewall/zones, this
# connection request will be passed
# to the rules defined for that
# (those) zone(s).
# LOG -- Simply log the packet and continue.
# QUEUE -- Queue the packet to a user-space
# application such as ftwall
# (http://p2pwall.sf.net).
# <action> -- The name of an action defined in
# /etc/shorewall/actions or in
# /usr/share/shorewall/actions.std.
# <macro> -- The name of a macro defined in a
# file named macro.<macro-name>. If
# the macro accepts an action
# parameter (Look at the macro
# source to see if it has PARAM in
# the TARGET column) then the macro
# name is followed by "/" and the
# action (ACCEPT, DROP, REJECT, ...)
# to be substituted for the
# parameter. Example: FTP/ACCEPT.
#
# The ACTION may optionally be followed
# by ":" and a syslog log level (e.g, REJECT:info or
# DNAT:debug). This causes the packet to be
# logged at the specified level.
#
# If the ACTION names an action defined in
# /etc/shorewall/actions or in
# /usr/share/shorewall/actions.std then:
#
# - If the log level is followed by "!' then all rules
# in the action are logged at the log level.
#
# - If the log level is not followed by "!" then only
# those rules in the action that do not specify
# logging are logged at the specified level.
#
# - The special log level 'none!' suppresses logging
# by the action.
#
# You may also specify ULOG (must be in upper case) as a
# log level.This will log to the ULOG target for routing
# to a separate log through use of ulogd
# (http://www.gnumonks.org/projects/ulogd).
#
# Actions specifying logging may be followed by a
# log tag (a string of alphanumeric characters)
# are appended to the string generated by the
# LOGPREFIX (in /etc/shorewall/shorewall.conf).
#
# Example: ACCEPT:info:ftp would include 'ftp '
# at the end of the log prefix generated by the
# LOGPREFIX setting.
#
# SOURCE Source hosts to which the rule applies. May be a zone
# defined in /etc/shorewall/zones, $FW to indicate the
# firewall itself, "all", "all+" or "none" If the ACTION
# is DNAT or REDIRECT, sub-zones of the specified zone
# may be excluded from the rule by following the zone
# name with "!' and a comma-separated list of sub-zone
# names.
#
# When "none" is used either in the SOURCE or DEST
# column, the rule is ignored.
#
# When "all" is used either in the SOURCE or DEST column
# intra-zone traffic is not affected. When "all+" is
# used, intra-zone traffic is affected.
#
# Except when "all[+]" is specified, clients may be
# further restricted to a list of subnets and/or hosts by
# appending ":" and a comma-separated list of subnets
# and/or hosts. Hosts may be specified by IP or MAC
# address; mac addresses must begin with "~" and must use
# "-" as a separator.
#
# Hosts may be specified as an IP address range using the
# syntax <low address>-<high address>. This requires that
# your kernel and iptables contain iprange match support.
# If you kernel and iptables have ipset match support
# then you may give the name of an ipset prefaced by "+".
# The ipset name may be optionally followed by a number
# from 1 to 6 enclosed in square brackets ([]) to
# indicate the number of levels of source bindings to be
# matched.
#
# dmz:192.168.2.2 Host 192.168.2.2 in the DMZ
#
# net:155.186.235.0/24 Subnet 155.186.235.0/24 on the
# Internet
#
# loc:192.168.1.1,192.168.1.2
# Hosts 192.168.1.1 and
# 192.168.1.2 in the local zone.
# loc:~00-A0-C9-15-39-78 Host in the local zone with
# MAC address 00:A0:C9:15:39:78.
#
# net:192.0.2.11-192.0.2.17
# Hosts 192.0.2.11-192.0.2.17 in
# the net zone.
#
# Alternatively, clients may be specified by interface
# by appending ":" to the zone name followed by the
# interface name. For example, loc:eth1 specifies a
# client that communicates with the firewall system
# through eth1. This may be optionally followed by
# another colon (":") and an IP/MAC/subnet address
# as described above (e.g., loc:eth1:192.168.1.5).
#
# DEST Location of Server. May be a zone defined in
# /etc/shorewall/zones, $FW to indicate the firewall
# itself, "all". "all+" or "none".
#
# When "none" is used either in the SOURCE or DEST
# column, the rule is ignored.
#
# When "all" is used either in the SOURCE or DEST column
# intra-zone traffic is not affected. When "all+" is
# used, intra-zone traffic is affected.
#
# Except when "all[+]" is specified, the server may be
# further restricted to a particular subnet, host or
# interface by appending ":" and the subnet, host or
# interface. See above.
#
# Restrictions:
#
# 1. MAC addresses are not allowed.
# 2. In DNAT rules, only IP addresses are
# allowed; no FQDNs or subnet addresses
# are permitted.
# 3. You may not specify both an interface and
# an address.
#
# Like in the SOURCE column, you may specify a range of
# up to 256 IP addresses using the syntax
# <first ip>-<last ip>. When the ACTION is DNAT or DNAT-,
# the connections will be assigned to addresses in the
# range in a round-robin fashion.
#
# If you kernel and iptables have ipset match support
# then you may give the name of an ipset prefaced by "+".
# The ipset name may be optionally followed by a number
# from 1 to 6 enclosed in square brackets ([]) to
# indicate the number of levels of destination bindings
# to be matched. Only one of the SOURCE and DEST columns
# may specify an ipset name.
#
# The port that the server is listening on may be
# included and separated from the server's IP address by
# ":". If omitted, the firewall will not modifiy the
# destination port. A destination port may only be
# included if the ACTION is DNAT or REDIRECT.
#
# Example: loc:192.168.1.3:3128 specifies a local
# server at IP address 192.168.1.3 and listening on port
# 3128. The port number MUST be specified as an integer
# and not as a name from /etc/services.
#
# if the ACTION is REDIRECT, this column needs only to
# contain the port number on the firewall that the
# request should be redirected to.
#
# PROTO Protocol - Must be "tcp", "udp", "icmp", "ipp2p",
# "ipp2p:udp", "ipp2p:all" a number, or "all".
# "ipp2p*" requires ipp2p match support in your kernel
# and iptables.
#
# DEST PORT(S) Destination Ports. A comma-separated list of Port
# names (from /etc/services), port numbers or port
# ranges; if the protocol is "icmp", this column is
# interpreted as the destination icmp-type(s).
#
# If the protocol is ipp2p, this column is interpreted
# as an ipp2p option without the leading "--" (example
# "bit" for bit-torrent). If no port is given, "ipp2p" is
# assumed.
#
# A port range is expressed as <low port>:<high port>.
#
# This column is ignored if PROTOCOL = all but must be
# entered if any of the following ields are supplied.
# In that case, it is suggested that this field contain
# "-"
#
# If your kernel contains multi-port match support, then
# only a single Netfilter rule will be generated if in
# this list and the CLIENT PORT(S) list below:
# 1. There are 15 or less ports listed.
# 2. No port ranges are included.
# Otherwise, a separate rule will be generated for each
# port.
#
# CLIENT PORT(S) (Optional) Port(s) used by the client. If omitted,
# any source port is acceptable. Specified as a comma-
# separated list of port names, port numbers or port
# ranges.
#
# If you don't want to restrict client ports but need to
# specify an ORIGINAL DEST in the next column, then
# place "-" in this column.
#
# If your kernel contains multi-port match support, then
# only a single Netfilter rule will be generated if in
# this list and the DEST PORT(S) list above:
# 1. There are 15 or less ports listed.
# 2. No port ranges are included.
# Otherwise, a separate rule will be generated for each
# port.
#
# ORIGINAL DEST (0ptional) -- If ACTION is DNAT[-] or REDIRECT[-]
# then if included and different from the IP
# address given in the SERVER column, this is an address
# on some interface on the firewall and connections to
# that address will be forwarded to the IP and port
# specified in the DEST column.
#
# A comma-separated list of addresses may also be used.
# This is usually most useful with the REDIRECT target
# where you want to redirect traffic destined for
# particular set of hosts.
#
# Finally, if the list of addresses begins with "!" then
# the rule will be followed only if the original
# destination address in the connection request does not
# match any of the addresses listed.
#
# For other actions, this column may be included and may
# contain one or more addresses (host or network)
# separated by commas. Address ranges are not allowed.
# When this column is supplied, rules are generated
# that require that the original destination address
# matches one of the listed addresses. This feature is
# most useful when you want to generate a filter rule
# that corresponds to a DNAT- or REDIRECT- rule. In this
# usage, the list of addresses should not begin with "!".
#
# See http://shorewall.net/PortKnocking.html for an
# example of using an entry in this column with a
# user-defined action rule.
#
# RATE LIMIT You may rate-limit the rule by placing a value in
# this colume:
#
# <rate>/<interval>[:<burst>]
#
# where <rate> is the number of connections per
# <interval> ("sec" or "min") and <burst> is the
# largest burst permitted. If no <burst> is given,
# a value of 5 is assumed. There may be no
# no whitespace embedded in the specification.
#
# Example: 10/sec:20
#
# USER/GROUP This column may only be non-empty if the SOURCE is
# the firewall itself.
#
# The column may contain:
#
# [!][<user name or number>][:<group name or number>][+<program name>]
#
# When this column is non-empty, the rule applies only
# if the program generating the output is running under
# the effective <user> and/or <group> specified (or is
# NOT running under that id if "!" is given).
#
# Examples:
#
# joe #program must be run by joe
# :kids #program must be run by a member of
# #the 'kids' group
# !:kids #program must not be run by a member
# #of the 'kids' group
# +upnpd #program named upnpd (This feature was
# #removed from Netfilter in kernel
# #version 2.6.14).
#
# Example: Accept SMTP requests from the DMZ to the internet
#
# #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL
# # PORT PORT(S) DEST
# ACCEPT dmz net tcp smtp
#
# Example: Forward all ssh and http connection requests from the
# internet to local system 192.168.1.3
#
# #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL
# # PORT PORT(S) DEST
# DNAT net loc:192.168.1.3 tcp ssh,http
#
# Example: Forward all http connection requests from the internet
# to local system 192.168.1.3 with a limit of 3 per second and
# a maximum burst of 10
#
# #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL RATE
# # PORT PORT(S) DEST LIMIT
# DNAT net loc:192.168.1.3 tcp http - - 3/sec:10
#
# Example: Redirect all locally-originating www connection requests to
# port 3128 on the firewall (Squid running on the firewall
# system) except when the destination address is 192.168.2.2
#
# #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL
# # PORT PORT(S) DEST
# REDIRECT loc 3128 tcp www - !192.168.2.2
#
# Example: All http requests from the internet to address
# 130.252.100.69 are to be forwarded to 192.168.1.3
#
# #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL
# # PORT PORT(S) DEST
# DNAT net loc:192.168.1.3 tcp 80 - 130.252.100.69
#
# Example: You want to accept SSH connections to your firewall only
# from internet IP addresses 130.252.100.69 and 130.252.100.70
#
# #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL
