I like that in the latest firmware LTE automatically has DHCP-Client applied so you can just plug a USB modem in and the router will automatically have an internet connection, but clients behind it still don’t.
I use multiple firewall rules (including NAT rule) with an interface list, I need the LTE interface to be added to this list. This is no problem if plugging a USB modem in before sending the mikrotik router out to a client, but if they later need a 4G backup we still have to log in manually and add the LTE interface to the interface list
Is there a way to have this happen automatically?
