I have two of the new mac airport extreme ac units linked by a cable. One is on the third fl. and a new airport express linked wireless in the garage. The main one has the IPv4 enabled. Do I want to enable the third fl and the express IPv4 units or is a pass through from the main airport extreme . TW is the incoming service. There is an apple tv linked to the airport ac on the third fl.
