It seems that the ether5 is disabled.

Could you post here IP → Address ?

Seems a strange way of doing it. Why would you want to bridge you wan ports?

Set your default route (0.0.0.0/0) to your primary wan and do the same to your backup wan with a higher distance cost. Then just src nat.

That way you can also put specific routes or services over your backup wan

Search for dual wan backup configuration scenario and try it. If you have problems using Google, look for example at this. https://aacable.wordpress.com/2013/04/12/mikrotik-multiple-wan-fail-over-scripts/
