Clarifying: so you connect $something to the cable modem. Make a dhcp request and get back your public ip (and some dns servers). But it isn't doing nat or handing out local addresses to your local network. Right? _Or_ it's a combined modem-and-router-in-one which manages your local subnet for you and you can't configure how it does this at all beyond switching the router part off and using a separate router. That sounds nuts?
