# Shorewall6 version 4 - Audited Drop Action
#
# /usr/share/shorewall6/action.ADrop
#
# The Audited default DROP common rules
#
# This action is invoked before a DROP policy is enforced. The purpose
# of the action is:
#
# a) Avoid logging lots of useless cruft.
# b) Ensure that 'auth' requests are rejected, even if the policy is
# DROP. Otherwise, you may experience problems establishing
# connections with servers that use auth.
# c) Ensure that certain ICMP packets that are necessary for successful
# internet operation are always ACCEPTed.
#
# IF YOU ARE HAVING CONNECTION PROBLEMS, CHANGING THIS FILE WON'T HELP!!!!!!!!!
