Initial network configuration help

Good morning, setting up our 2.3 community and looking for some help from the forum.  This is for a small office with a static IP from our ISP.  Behind is the basic 10.x which is working fine, and I can start the setup.  I also have a backup DSL line being installed for internet redundancy as we have had some outages.  The setup shows Network Interfaces 4 which is correct, so I am wondering what will be the backup.

The green is naturally the 10.x
The red is my primary providers public IP.

Now I see an orange and green and wondering which (or is there another way) to setup that DSL to be a 'failover'.  I would like it to be automatic (maybe even notify) on failover, but what's the best way to go about setting this configuration up.

Thanks.
