Ok, things are starting to make a little more sense, thank you all. I was ready to assign an IP of 2002: to a windows xp client when I realized that this machine is behind a firewall and has a nat'ed address of 10.0.10.x. I would not think that would be allowed. Is this a correct assumption?

Things are even clearer now But. I am running radvd on the firewall, and I have it advertising a /48 to my internal machines. radvd avertises on eth1, which is the lan side of the router. The winxp and linux clients on the inside both pick up addresses from the advertising router. I can
