# The Audited default DROP common rules
8
# This action is invoked before a DROP policy is enforced. The purpose
11
# a) Avoid logging lots of useless cruft.
12
# b) Ensure that 'auth' requests are rejected, even if the policy is
13
# DROP. Otherwise, you may experience problems establishing
14
# connections with servers that use auth.
15
# c) Ensure that certain ICMP packets that are necessary for successful
16
# internet operation are always ACCEPTed.
18
# IF YOU ARE HAVING CONNECTION PROBLEMS, CHANGING THIS FILE WON'T HELP!!!!!!!!!
