# Shorewall -- /usr/share/shorewall/action.A_Reject
|
|
#
|
|
# The audited 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!!!!!!!!!
