Cannot add NAT rules after creating and deleting multiple NAT connections

Hello,

I'm running into a situation where if I create multiple NAT connections on a single VMNetworkGateway via PowerShell, and then delete one of them, I am no longer able to add NAT rules. I'm running SCVMM under Windows 2012 R2.

It's quite easy to reproduce. The first commands run with no problems:

Add-SCVMNetworkGateway -Name "Gateway" -EnableBGP $false -NetworkGateway $gatewaydevice -VMNetwork $vmnetwork
$nat1 = Add-SCNATConnection -Name "nat1" -VMNetworkGateway $vmnetworkgateway -ExternalIPPool $externalippoolvar
$nat2 = Add-SCNATConnection -Name "nat2" -VMNetworkGateway $vmnetworkgateway -ExternalIPPool $externalippoolvar
Remove-SCNATConnection -NATConnection $nat1

But then at this point, any attempts to add a NAT connection will fail:

Add-SCNATRule -Name "rule1" -Protocol "TCP" -InternalIPAddress 192.168.90.90 -InternalPort 8080 -ExternalPort 8080 -NATConnection $nat2

Check the documentation for the configuration provider or contact the publisher support.

Any ideas, or has anyone seen this before?

Thanks,
