#
# This module should be placed in /etc/firewall/modules/public/services.
# You'll also need the port forwarding module (in public/port-forwarding)
#
# After installing the module, the user should execute rc.firewall with
# the --update-config parameter. The necessary options will be added to
# the configuration file.
