Hello Julien,


I am happy, that your traffic now flows as it should!

Instead of simply disabling it, I would suggest to inspects its current state /
set of rules and clarify whether it serves a purpose.
In case that there are _no_ rules right now, it means that incoming traffic
from any interface can communicate into any other interface on that host (and
to all services on that host itself).
I do not want to scare you for no reason - I just want to make sure, that you
understand what you are doing :)

Cheers,
LArs
