The following diagram represents my current network.

I would like for the Phone and the Laptop both on wireless to have internet access but not access to the other PCs/shares.
I have access to routing tables in both the cable router 10.0.0.1 and the wireless router
any ideas?
--edit
router models:
- wired : ASUS RX3042H
- wireless : Linksys WRT54G (default Firmware)
