    1. Private NAT for VM outbound to on prem

      If an Azure VM sits in a vnet (call it app-vnet) peered with a vnet that's VPN connected (call it vpn-vnet) to on-prem, and the VM needs to establish connectivity with an on-prem VM, a NAT gateway cannot snat the traffic from app-vnet using an IP from vpn-vnet, since the only kind of outbound IP a NAT gateway can use is a public IP.
      I actually don't know what azure solution could snat from a vnet using a private outbound IP of another vnet... Azure Firewall maybe?

    2. Zone-redundant NAT Gateway

      Since subnets are regional, not zonal, and can only be associated with a maximum of one NAT gateway, it seems that deployments would be much simpler if NAT gateways were supported in a zone-redundant mode.

      This is something you offer with Standard Load Balancer, so why can't it be provided by NAT gateways?

      Currently, I either must: (1) forego any failure isolation promises and go with a regional NAT, or (2) double or triple the number of subnets I manage just so a zone-isolated NAT can be assigned to each. That makes a complicated, messy deployment that wasn't required for…
