Issue with Natanator and dubble Wan interface activated on 3.2.7

[ronnieollila]

We upgraded to 3.2.7 on UDM Pro and after that we got problem with the Natanator. Its working when we have only one WAN interface activated but if we have both (WAN and LTE failover activated) then we do not get any traffic from inside out to the internet.

We do not have the problem if the Natanator is Deactivated on the UDM.
