You're welcome, Stuart. I'm glad that I could clear up the subject
for you. In my opinion, the Network Setup Wizard (which is supposed
to make things easy) doesn't describe the options clearly. It's a
little better in the forthcoming Windows XP Service Pack 2.
I've mentioned to some of Microsoft's network software developers that
most home users don't know what "residential gateway" means -- users
and manufacturers call it a "broadband router" or just a "router".
