I have a system using Connman 1.33 and I would like to setup a firewall.
At that time, I’m using iptables rules but I would like to setup the rules when a service is activated in Connman (similar to what can be done with if-up.d).
I have checked README and main.conf but can’t find related information and it seems (from an old thread https://lists.01.org/pipermail/connman/2016-January/000223.html) that the firewall settings is limited.
Is there a way to a trigger script or D-Bus event on interface activation in Connman?
Is there a better way to setup a firewall in Connman?
