# Shorewall 1.3 -- /etc/shorewall/common.def

#
|
|
# This file defines the rules that are applied before a policy of
|
|
# DROP or REJECT is applied. In addition to the rules defined in this file,
|
|
# the firewall will also define a DROP rule for each subnet broadcast
|
|
# address defined in /etc/shorewall/interfaces (including "detect").
|
|
#
|
|
# Do not modify this file -- if you wish to change these rules, create
|
|
# /etc/shorewall/common to replace it. It is suggested that you include
|
|
# the command ". /etc/shorewall/common.def" in your
|
|
# /etc/shorewall/common file so that you will continue to get the
|
|
# advantage of new releases of this file.
