Cirrus AP + 4G backup?

Hi ! Recently I bought a Cirrus Router, I want to know if theres a way to using as a bridge (not wifi bridge) (maybe AP ?) and keep the 4G LTE backup if the wan fails, am asking this because It use other ip’s that my main router and I want to include the Cirrus to the main ip’s but keeping the 4g backup to an specific devices that use the Cirrus Lan port. It is possible? :nerd_face:

This may be possible, but very complicated.

It will break the current multi-wan failsafe settings. You may also need to write some scripts to do this.
