# Shorewall 2.0 -- Policy File
#
# /etc/shorewall/policy
#
# THE ORDER OF ENTRIES IN THIS FILE IS IMPORTANT
#
# This file determines what to do with a new connection request if we
# don't get a match from the /etc/shorewall/rules file . For each
# source/destination pair, the file is processed in order until a
# match is found ("all" will match any client or server).
#
# Columns are:
#
# SOURCE Source zone. Must be the name of a zone defined
# in /etc/shorewall/zones, $FW or "all".
#
# DEST Destination zone. Must be the name of a zone defined
# in /etc/shorewall/zones, $FW or "all"
#
# POLICY Policy if no match from the rules file is found. Must
# be "ACCEPT", "DROP", "REJECT", "CONTINUE" or "NONE".
#
# ACCEPT - Accept the connection
# DROP - Ignore the connection request
# REJECT - For TCP, send RST. For all other, send
# "port unreachable" ICMP.
# CONTINUE - Pass the connection request past
# any other rules that it might also
# match (where the source or destination
# zone in those rules is a superset of
# the SOURCE or DEST in this policy).
# NONE - Assume that there will never be any
# packets from this SOURCE
# to this DEST. Shorewall will not set up
# any infrastructure to handle such
# packets and you may not have any rules
# with this SOURCE and DEST in the
# /etc/shorewall/rules file. If such a
# packet _is_ received, the result is
# undefined. NONE may not be used if the
# SOURCE or DEST columns contain the
# firewall zone ($FW) or "all".
#
# If this column contains ACCEPT, DROP or REJECT and a
# corresponding common action is defined in
# /etc/shorewall/actions (or /usr/share/shorewall/actions.std)
# then that action will be invoked before the policy named in
# this column is inforced.
#
# LOG LEVEL If supplied, each connection handled under the default
# POLICY is logged at that level. If not supplied, no
# log message is generated. See syslog.conf(5) for a
# description of log levels.
#
# Beginning with Shorewall version 1.3.12, you may
# also specify ULOG (must be in upper case). This will
# log to the ULOG target and sent to a separate log
# through use of ulogd
# (http://www.gnumonks.org/projects/ulogd).
#
# If you don't want to log but need to specify the
# following column, place "-" here.
#
# LIMIT:BURST If passed, specifies the maximum TCP connection rate
# and the size of an acceptable burst. If not specified,
# TCP connections are not limited.
#
# As shipped, the default policies are:
#
# a) All connections from the local network to the internet are allowed
# b) All connections from the internet are ignored but logged at syslog
# level KERNEL.INFO.
# d) All other connection requests are rejected and logged at level
# KERNEL.INFO.
