Subject: [Buildroot] [PATCH v3] package/iptables: add init script
Date: Wed, 15 Sep 2021 16:06:20 +0300 [thread overview]
Message-ID: <20210915130620.3162787-1-jose.pekkarinen@unikie.com> (raw)
This patch will add an init script that allows
to set a ruleset in /etc/iptables.conf to be loaded
on boot, or flushed on stop, as well as a saving
command to generate a new file.
