#
# Shorewall - /usr/share/shorewall/action.BLACKLIST
#
# This action:
#
#   - Adds the sender to the dynamic blacklist ipset
#   - Optionally acts on the packet (default is DROP)
#
# Parameters:
#
# 1 - Action to take after adding the packet. Default is DROP.
#     Pass -- if you don't want to take any action.
# 2 - Timeout for ipset entry. Default is the timeout specified in
#     DYNAMIC_BLACKLIST or the one specified when the ipset was created.

# Note -- This action is defined with the 'section' option, so the first
#         parameter is always the section name. That means that in the
#         following text, the first parameter passed in the rule is actually
#         @2.
