How to setup a LAN (primary) to SIM (secondary) failover for continuous connection.

Hello,

One of my clients sites has a ADSL connection which is flakey and loses connection periodically. We need to keep the server visible via a DDNS using the ADSL via Eth1 as the primary route and when it fails, to switch over to the 4G comms until the ADSL service has returned.

Do you have documentation or knowledge base that covers this?

Thank you.

It's a Digi Transport WR21 router.
Take a look at Application Note 41 and 71 which you can find here:

Those should be able to point you in the right direction.
