				ncAuthorUnsubmitted Done Inline Actions Fixed it. nc: Fixed it.
				donnerUnsubmitted Done Inline Actions No no. The concern is only valid as long as the documentation about the half open interval was missing. The configuration you need (using half open intervals) is 2000 3000 and 3000 4000 in order to match the port ranges in lines 187-188 below. donner: No no.

				donnerUnsubmitted Done Inline Actions Line 187 and 188 have exactly the same match, so only 187 is invoked. 188 will never be used. Furthermore they are only outgoing (for aliasing), they do not match incoming packets (for dealiasing) donner: Line 187 and 188 have exactly the same match, so only 187 is invoked. 188 will never be used.
