# Shorewall version 4 - Reject Action
#
# /usr/share/shorewall/action.Reject
#
# The default REJECT action common rules
#
# This action is invoked before a REJECT policy is enforced. The purpose
# of the action is:
#
# a) Avoid logging lots of useless cruft.
# b) 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!!!!!!!!!
