Bridge mode as a guest network?
I have one airport extreme as the router at my dental practice with a very long and very strong password. If I setup a second airport extreme up in the waiting room and create a new wireless network and set it to bridge mode with wpa/wpa2 password, have I sufficiently made a pathway to the internet for patients without providing a hole to more sensitive areas of our back office wifi and lan network? If not, is it possible and what settings should I be aware of. I was able to set this up and create a second network that I could connect to the internet with my iphone, but I am concerned as to if I have taken the appropriate security precautions or if making it really secure is even possible. I have unplugged the bridged airport until I get some feedback from you guys.
