USG FLEX 500 NAT Fallover

I have a USG Flex 500 configured with Port forwarding rules and 2 WAN ports in use.

All forwarded ports are from the primary used WAN but if that WAN fails all those ports stop working.

Is there a way to have NAT rules switch to the backup WAN when the primary fails?

I couldn't really find an answer in the manual for this.

    Two WAN IP's that are different and are fully routable you likely have a DNS name to one WAN IP for the port forwarded because your still going to the same WAN IP that is down you will never use the other WAN IP so you need to have your DNS point to your other WAN IP.
