Timed Access Control questions

I have a Time Capsule at the center of my network and my kid's access is controlled by time slots defined by MAC address. I have an airport express set up to extend the wireless network (and I have extension allowed on the Time Capsule). Do I need to enter all the access time slots in the Airport Express configuration too or will the MAC be blocked when the request is routed from the Express to the Capsule?

THanks!
