Netgear WG302 Isolation

Hi,

i'm trying to set up a Hotspot using the above WAP (Netgear ProSafe WG302v2)

It has an option in the wireless security setup to isolate the wireless users from each other. This is fine.

What I really want to do is isolate the wireless users from any machines that are on my LAN.

How do I do it?

Thanks,
