Either
    route the "internal" machines straight to the internet, since each
    has its own (public) IP anyways,
or
    use masquerading (RTFM on NAT at netfilter.samba.org) to make the
    internal machines invisible and all traffic appears to come from
    the gateway.  In this situation you do not need public IPs for the
    internal machiens

After you install Microsoft Windows XP, you have the option to create
user accounts.  If you create user accounts, by default, they will have
an account type of administrator with no password.
