# Shorewall 2.4 /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!!!!!!!!!!!!
