|
# 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!!!!!!!!!
