In Lime 17.06 I was adding two basic iptables rules to /etc/firewall.user
Now I have compiled from source (based on OpenWRT 18.06) and see
different firewall files. Where should I add my two lines?
/etc/firewall.lime.d contains three files with rules. Their name start
with "20", I don't know why.
I'm not sure if this is the correct way but I added a fourth file with
my two iptables lines and it seems to work.
