Sheng Yang commented on CLOUDSTACK-4745:
----------------------------------------
The StaticNatRule object should be applied by firewall, rather than static nat
service provider. In the future we need to move every StaticNatRule to
StaticNat, and update the db as well. It has already caused too many confusions.
> Exception happened when try to apply static nat rule using
> CreateIpForwardingCmd API
