Make iOS devices not visible to network through wireless AP or Bluetooth AP?

Hi

I have some iOS devices that I need to connect to a wired corporate network through wireless or Bluetooth.

I only have one wired data port and only one device is authorised to connect to the network through a single port at any one time.  I need to install a wireless AP or router into that data port but can I configure that AP and iOS devices in such a way that only the AP is visible to the network?

(Yes the simple answer is to get authorisation and network configured for the AP with multiple devices but for many reasons that is just not going to happen!)

So, I have the IP and MAC of the one device - the AP - approved for connection.  But then is there any way I can have the iOS devices talking to the network through the AP without being seen as additional devices?  Ie everything is communicating through the AP's connection and IP.

The iOS devices are customised for our bespoke app and only need to poll one fixed IP of our server on the LAN to send and pick up pre determined files.  No domain authentication, no internet access, no server to device connection needed.

I just don't know enough about networking to know if this is possible.  However, I am thinking for example, that at home with my broadband router, the router has a single IP address that is visible to the internet and all my local devices are on the router's local DHCP with the router's local IP range.  The internet can't see my local devices - their IPs or MACs - only the router's IP and MAC. If I translate that to my problem and assume the internet is the corporate network, this is what I am trying to achieve.

So can I configure a wireless AP or wireless router in such a way to achieve this on my corporate network?

Also, is there a better way to achieve this with a Bluetooth AP?  I'm just guessing here, but can Bluetooth devices be configured to talk to the AP/base station in a non IP way so the devices are not 'seen' on the corporate network but can, via the AP/base station, poll that server IP address.

Hope that makes sense!  

Thanks
