I was a litle bit unclear there! I meant that the NetBSD box doesn't get the ISP assigned public address, but a non-assigned one (192.168.0.2) from the modem. The Windows box gets the ISP assigned one ... I tried disconnecting the Windows machine, configuring the NetBSD one with the same address, gateway DNS server, etc. and then plugging it in. To my increased frustration and confusion it still didn't work.

I'm going away for New Years Eve very soon, but I'll bite the bullet and look at tcpdump output when I get back. By the way, is ethereal a better option for diagnosing DHCP problems?
