* to enable 1-1 nat for ip/vm use enalbeOneToOneNat api
* to open port range (or multiple port ranges) use createIpForwardingRule api.
* to delete one port range use deleteIpForwardingRule api.
* to disable 1-1 nat use disableOneToOneNat api.
* API requires network id to be passed in (it was optional before)
