# Shorewall 2.2 /etc/shorewall/action.template
#
# This file is a template for files with names of the form
# /etc/shorewall/action.<action-name> where <action> is an
# ACTION defined in /etc/shorewall/actions.
#
# To define a new action:
#
# 1. Add the <action name> to /etc/shorewall/actions
# 2. Copy this file to /etc/shorewall/action.<action name>
# 3. Add the desired rules to that file.
#
# Columns are:
#
#
# TARGET ACCEPT, DROP, REJECT, LOG, QUEUE or a
# previously-defined <action>
#
# ACCEPT -- allow the connection request
# DROP -- ignore the request
# REJECT -- disallow the request and return an
# icmp-unreachable or an RST packet.
# LOG -- Simply log the packet and continue.
# QUEUE -- Queue the packet to a user-space
# application such as p2pwall.
# CONTINUE -- Discontinue processing this action
# and return to the point where the
# action was invoked.
# <action> -- An <action> defined in
# /etc/shorewall/actions. The <action>
# must appear in that file BEFORE the
# one being defined in this file.
#
# The TARGET may optionally be followed
# by ":" and a syslog log level (e.g, REJECT:info or
# ACCEPT:debugging). This causes the packet to be
# logged at the specified level.
#
# The special log level 'none' does not result in logging
# but rather exempts the rule from being overridden by a
# non-forcing log level when the action is invoked.
#
# 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.
# 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.
#
# 192.168.2.2 Host 192.168.2.2
#
# 155.186.235.0/24 Subnet 155.186.235.0/24
#
# 10.0.0.4-10.0.0.9 Range of IP addresses; your
# kernel and iptables must have
# iprange match support.
#
# 192.168.1.1,192.168.1.2
# Hosts 192.168.1.1 and
# 192.168.1.2.
# ~00-A0-C9-15-39-78 Host with
# MAC address 00:A0:C9:15:39:78.
#
# Alternatively, clients may be specified by interface
# name. For example, 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., eth1:192.168.1.5).
#
# DEST Location of Server. Same as above with the exception that
# MAC addresses are not allowed.
#
# PROTO Protocol - Must be "tcp", "udp", "icmp", a number, or
# "all".
#
# 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).
#
# 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 fields 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.
#
# SOURCE 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 ADDRESS 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.
#
# RATE LIMIT You may rate-limit the rule by placing a value in
# this column:
#
# <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>]
#
# 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
