[Buildroot] iptable configuration

I had the same problem. You can find how to make some rules in this
link [1], and then you will have to save the configuration file with
this command:

$ iptables-save > /etc/iptables.rules

You can restore the configuration file with this other command:

$  iptables-restore < /etc/iptables.rules

But YES, buildroot doesn't make a default configuration file and you
will have to load it with a init script made on your own.


Best regards.
