A parameter cannot found error while executing Add-AzureRmLoadBalancerInboundNatRuleConfig

Hi,

I am trying to follow the example on this page: https://msdn.microsoft.com/en-us/library/mt619382.aspx

But it seems Add-AzureRmLoadBalancerInboundNatRuleConfig does not have a BackendIpConfiguration option.

So how can I define backendipconfiguration for new inbound nat rule?
