#
# Note about policies and logging:
# This file contains an explicit policy for every combination of
# zones defined in this sample. This is solely for the purpose of
# providing more specific messages in the logs. This is not
# necessary for correct operation of the firewall, but greatly
# assists in diagnosing problems. The policies below are logically
# equivalent to:
#
# loc net ACCEPT
# net all DROP info
# all all REJECT info
#
# The Shorewall-perl compiler will generate the individual policies
# below from the above general policies if you set
# EXPAND_POLICIES=Yes in shorewall.conf.
#
#
# Policies for traffic originating from the local LAN (loc)
#
# If you want to force clients to access the Internet via a proxy server
# in your DMZ, change the following policy to REJECT info.
loc net ACCEPT
# If you want open access to DMZ from loc, change the following policy
# to ACCEPT. (If you chose not to do this, you will need to add a rule
# for each service in the rules file.)
loc dmz REJECT info
loc $FW REJECT info
loc all REJECT info
#
# Policies for traffic originating from the firewall ($FW)
#
# If you want open access to the Internet from your firewall, change the
# $FW to net policy to ACCEPT and remove the 'info' LOG LEVEL.
$FW net REJECT info
$FW dmz REJECT info
$FW loc REJECT info
$FW all REJECT info
#
# Policies for traffic originating from the De-Militarized Zone (dmz)
#
# If you want open access from DMZ to the Internet change the following
# policy to ACCEPT. This may be useful if you run a proxy server in
# your DMZ.
dmz net REJECT info
dmz $FW REJECT info
dmz loc REJECT info
dmz all REJECT info
#
# Policies for traffic originating from the Internet zone (net)
#
net dmz DROP info
net $FW DROP info
net loc DROP info
net all DROP info
# THE FOLLOWING POLICY MUST BE LAST
all all REJECT info
