For ip-type=shared the communication stays in the system.  O(memory  
speed).  Very fast with little IP processing. This is the default.

For ip-type=exclusive the communication will have to go out the  
interface assigned to the nonglobal zone and routed externally to an  
interface on the global zone. It is visible and the transfer is  
O(slowest interface).
