you most likely are going to have to go from Bell copper line - > aDSL Mode, -> Ethernet switch - > then you can either connect to a PC or device or router and each will get its own external lan ip. this depends on how you need to configure your setup. how many devices do you require external lan IP's?

your router will only handle one external lan IP, but the router shares the one ip with multiple devices, not sure what your trying to acomplish here?
