I have had the same problem. Before that dumb-arse MobileMe took over, You would tell your domain manager to forward some ports and anyone typing in your mac address would be taken to your real site, which then could be made in iWeb. But after they updated to MobileMe, the forwarding stopped working. I have yet to to try to set it back up because my domain says everything is working fine, but it is not, and I don’t have the patience to deal with it right now. I think you just have to reestablish the connection, which involves dealing with your domain, not mac… I think. Don’t quote me on that.
