And thank you for your interest in OpenWRt.<br>
<br>
In general, in OpenWRt, pieces work togeter because they are developed to do so.<br>
A connection manager duty is not, arguably, to set up firewall rules.<br>
you can surely inspect a lot of the informations you would need from the UCI interface / libraries, and ubus itself.<br>
If the modem is QMI based, you may switch to upstream connection manager solutions, which would help in some regards.<br>
Or maybe using a ModemManager-based solution?<br>
<br>
Thanks,<br>
