Hi Attilio, I'm pretty sure the answer to (1) is yes, as for (2) I can't answer with certainty off the top of my head but I think that's the right syntax too (I'd just try it out with wireshark running on both interfaces to verify that I'm getting the wanted behavior. Looking at the OF spec would help too. Section 3.3 describes the use of actions)
