The boxes all end up with the same IP subnet and everything, but you can't get from the wireless to the wired network w/o going through the firewall.
I am doing this with a hacked WRT54G, I am not sure how you would do that with the Cisco router.
Usually done with a Cisco Router and Cisco Switch. The switch handling the VLANs and the router handling IP traffic. I've been told there are several methods in configuring the Cisco IOS to do this, and not only by separating it out in VLANS either.
