Manpages written for expert? I dunno about that. But let's have a look
at your natd configuration,

Hmmm... Is that really what you mean to do? All incoming connections
are being redirected to 10.0.0.1 which is the natd machine
itself... so why bother?

Now here, I do not see you ever assigning your interfaces any IP
addresses. You also set no default router, so your packets don't know
how to get to the Internet.
