How choose Availability zone?

[MrCybertux]

When Moving the VM to a zone i get really weird errors:

But for our active active deployment 2 zones are a must for the customer so there is no way around it.
How to set this up?

@MrCybertux, the project was never tested in multi-zone options and I personally never tried to move an instance of OPNSense to a different zone. But I don't see why it shouldn't work, we create a few InboundNatRules in the Azure Load Balancer which you can remove prior to move it. It might fix your problem.
