We purchased 46 Digi TransPort WR44v2.

I am looking to see what is the easiest way to automatically failover from cellular signal (SIM) to ETH1 (that will come from Satellite).  
We need to set the ETH1 to 2nd priority over cellular as Satellite is much more expensive. Whenever cellular is available it should be used.

Any help would be greatly appreciated.

Not sure if this will help, stumbled on this, I would assume it works similar just have to give your Cellular a lower metric.

PS: I have not tried it myself.

Hi

Here is a Application Note on how to do this with monitoring  
[http://ftp1.digi.com/support/documentation/AN\_071%20Cellular%20WAN%20failover%20to%20Ethernet%20with%20Firewall%20Monitoring.pdf](http://ftp1.digi.com/support/documentation/AN_071%20Cellular%20WAN%20failover%20to%20Ethernet%20with%20Firewall%20Monitoring.pdf)

this goes through how to setup the firewall to monitor traffic and bring the cellular down if it cannot communicate.

this then allows traffic to flow on an ethernet interface

regards

James
