# Based on the work of ADNET Ghislain <gadnet@aqueos.com> from AQUEOS
# at https://reductivelabs.com/trac/puppet/wiki/AqueosShorewall
#
# Changes:
# * FHS Layout: put configuration in /var/lib/puppet/modules/shorewall and
# adjust CONFIG_PATH
# * remove shorewall- prefix from defines in the shorewall namespace
# * refactor the whole define structure
# * manage all shorewall files
# * add 000-header and 999-footer files for all managed_files
# * added rule_section define and a few more parameters for rules
# * add managing for masq, proxyarp, blacklist, nat, rfc1918
