		 You need a router/gateway, but it doesn't necessarily have to be a separate box. You can even set up a Windows machine to do it with built-in Internet Connection Sharing software. It'd connect to the modem, and then to the hub with all the other computers. Or the DSL modem could have a built in router with an uplink port for an external hub.
