# Shorewall -- /usr/share/shorewall/action.Reject
#
# The former default REJECT action common rules. Use of this action is deprecated.
#
# 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.
#
# The action accepts six optional parameters:
#
# 1 - 'audit' or '-'. Default is '-' which means don't audit in builtin
#     actions.
# 2 - Action to take with Auth requests. Default is to do nothing
#     special with them.
# 3 - Action to take with SMB requests. Default is REJECT or A_REJECT,
#     depending on the setting of the first parameter.
# 4 - Action to take with required ICMP packets. Default is ACCEPT or
#     A_ACCEPT depending on the first parameter.
# 5 - Action to take with late DNS replies (UDP source port 53). Default
#     is DROP or A_DROP depending on the first parameter.
# 6 - Action to take with UPnP packets. Default is DROP or A_DROP
#     depending on the first parameter.
#
# IF YOU ARE HAVING CONNECTION PROBLEMS, CHANGING THIS FILE WON'T HELP!!!!!!!!!
