I have a Modem -- Router -(192.168.1.xx)- Access Point. I would like to connect a router to the AP and the devices on the last router will have Internet access but NOT have access to the LAN 192.168.1.xx. Can this be done and if so how? The addresses assigned by this last router can be anything but not 192.168.1.xx. This last router will have a WAN address on 192.168.1.xxx.
