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)
        echo "<$1>: 
    May be either a host IP address such as 192.168.1.4 or a network address in
    CIDR format like 192.168.1.0/24"
	;;

allow)
	echo "allow: allow <address> ...
    Re-enables receipt of packets from hosts previously blacklisted
    by a drop, dropall, reject or rejectall command.

    Shorewall allow, drop, dropall, reject, rejectall, and save implement
    dynamic blacklisting.

    See also \"help address\""
	;;

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|dropall)
	echo "$1: $1 <address> ...
    Causes packets from the specified <address> to be ignored

    Shorewall allow, drop, dropall, reject, rejectall, and save implement
    dynamic blacklisting.

    'dropall' causes all interfaces to be monitored for packets from the
    given address while 'drop' causes only those interfaces with a route
    to the address to be monitored.

    See also \"help address\""
	;;

help)
	echo "help: help [<command> | host | address ]
    Display helpful information about the shorewall commands."
	;;

hits)
    echo "hits: hits
    Produces several reports about the Shorewall packet log messages
    in the current /var/log/messages file."
	;;

ipcalc)
	echo "ipcalc: ipcalc [ address mask | address/vlsm ]
    Ipcalc displays the network address, broadcast address,
    network in CIDR notation and netmask corresponding to the input[s]."
	;;

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."
	;;

	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|rejectall)
	echo "$1: $1 <address> ...
    Causes packets from the specified <address> to be rejected

    Shorewall allow, drop, dropall, reject, rejectall, and save implement
    dynamic blacklisting.

    'rejectall' causes all interfaces to be monitored for packets from the
    given address while 'reject' causes only those interfaces with a route
    to the address to be monitored.

reset)
	echo "reset: reset
    All the packet and byte counters in the firewall are reset."
