Multiple Public IP addresses on single Network Interface do not NAT to correct Private IP address

[lflint]

We have a single Network Interface with two IP Configurations, each with a public IP address:
IP Config 1 - 172.16.0.5 private IP, 160.200.200.5 public IP
IP Config 2 - 172.16.0.6 private IP, 160.200.200.6 public IP
Same NIC, subnet, and gateway.

When trying to connect to these from an external public IP address, connecting to either 160.200.200.5 or 160.200.200.6 will always connect to 172.16.0.5.

For example:
Connecting from x.x.x.x to 160.200.200.5 TCP port 80 will connect to 172.16.0.5 on the VM.
Connecting from x.x.x.x to 160.200.200.6 TCP port 80 will connect to 172.16.0.5 on the VM.

We expect x.x.x.x to 160.200.200.6 TCP port 80 to connect to 172.16.0.6 on the VM, since the .6 Public IP Address is assigned to the 172.16.0.6 Private IP Address.
