# Shorewall 1.4 /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.
# <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.
#
# 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).
#
# 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
#
# 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.
#
# Unlike in the SOURCE column, you may specify a range of
# up to 256 IP addresses using the syntax
# <first ip>-<last ip>.
#
# 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 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 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
#
# If you place a rate limit in this column, you may not
# place a similar limit in the TARGET column.

add)
echo "add: add <interface>[:<host>] <zone>
Adds a host or subnet to a dynamic zone usually used with VPN's.
shorewall add interface[:host] zone - Adds the specified interface
(and host if included) to the specified zone.
Example:
shorewall add ipsec0:192.0.2.24 vpn1 -- adds the address 192.0.2.24
from interface ipsec0 to the zone vpn1.
See also \"help host\""
;;
address|host)

;;
check)
echo "check: check [ -c <configuration-directory> ]
Performs a cursory validation of the zones, interfaces, hosts,
rules and policy files. Use this if you are unsure of any edits
you have made to the shorewall configuration. See the try command
examples for a recommended way to make changes."
;;
clear)
echo "clear: clear
Clear will remove all rules and chains installed by Shoreline.
The firewall is then wide open and unprotected. Existing
connections are untouched. Clear is often used to see if the
firewall is causing connection problems."
;;
debug)
echo "debug: debug
If you include the keyword debug as the first argument to any
of these commands:
start|stop|restart|reset|clear|refresh|check|add|delete
then a shell trace of the command is produced. For example:
shorewall debug start 2> /tmp/trace
The above command would trace the 'start' command and
place the trace information in the file /tmp/trace."
;;
delete)
echo "delete: delete <interface>[:<host>] <zone>
Deletes a host or subnet from a dynamic zone usually used with VPN's.
shorewall delete interface[:host] zone - Deletes the specified
interface (and host if included) from the specified zone.
Example:
shorewall delete ipsec0:192.0.2.24 vpn1 -- deletes the address
192.0.2.24 from interface ipsec0 from zone vpn1
See also \"help host\""
;;
drop)
echo "$1: $1 <address> ...

iprange)
echo "iprange: iprange address1-address2
Iprange decomposes the specified range of IP addresses into the
equivalent list of network/host addresses."
;;
logwatch)
echo "logwatch: logwatch [<refresh interval>]
Monitors the LOGFILE, $LOGFILE,
and produces an audible alarm when new Shorewall messages are logged."
;;
monitor)
echo "monitor: monitor [<refresh_interval>]
Continuously display the firewall status, last 20 log entries and nat.
When the log entry display changes, an audible alarm is sounded."
;;
refresh)
echo "refresh: refresh
The rules involving the broadcast addresses of firewall interfaces,
the black list, traffic control rules and ECN control rules are recreated
to reflect any changes made. Existing connections are untouched"
;;
reject)
echo "$1: $1 <address> ...
Causes packets from the specified <address> to be rejected

See also \"help address\""
;;
reset)
echo "reset: reset
All the packet and byte counters in the firewall are reset."
;;
restart)
echo "restart: restart [ -c <configuration-directory> ]
Restart is the same as a shorewall stop && shorewall start.
Existing connections are dropped."

The dynamic data is stored in /var/lib/shorewall/save
Shorewall allow, drop, rejct and save implement dynamic blacklisting."

shorewall show nat - produce a verbose report about the nat table.
(iptables -t nat -L -n -v)
shorewall show tos - produce a verbose report about the mangle table.
