I subscribe to Nabu Casa. I have a primary terrestrial Internet connection and secondary cell fail-over connection.
My router handles failover and fail back for outbound primary loss and regain very well.
Is there way to configure mobile devices, using Nabu Casa, to fail over to the secondary if the primary is down?
My networks skills are limited.
Do I need to setup a domain and configure the DNS to support both routes making one the primary?
Has anyone set this up? if so, can you provide guidance?
