Can anyone give me a laymans walk through to set up a zyxel 660r-c1 modem with an Apple Airport extreme.
I need the modem in straight through? mode to allow the airport to control the ins and outs.

System is:
Zyxel - airport.
To the airport is attached a Vodafone sure signal, my desk top, and a CCTV Alien system.
Wirelessly to 2 laptops and phones.

I currently have it all working with the airport in bridge, and all works except the iphone app on the cctv. I need to port forward? the cctv but with the airport in bridge, I can't do it that way, and the zyxel doesn't forward so I need the zyxel feeding the airport and the airport doing the work, if this makes sense?

Thanks guys
