Would this work? I thought the protocol mapped a host address to a MAC. If I did that and pulled the {blah} box back off the lease (post-suck) would the ethernet link bomb? Sure, could try this too. > And call your dopey Telco back -- that story doesn't check out.

If I tell them it doesn't support DHCP they're going to tell me to buy their cute little $600 router that'll do this for me.

I wasn't aware they made dsl equipment. Ugly little black box, looks like an audio CD Walkman that joined a gym a few months ago. RJ11 and RJ45 jacks for 10bt and DSL data. Its power supply failed today not more than a few hours before the installer came to add the audio/data splitter. It took some doing but after a long phone call at least he was persuaded to leave his (presumed functional) modem behind. Man I wish bpf was compiled in the GENERIC kernel, I really would have liked to have tried dhclient before unplugging the thing to go home.
