I cable ISP I work for uses both. The modem's MAC to identify the user as one of our customers, and the NIC's MAC to make sure the customer is only connecting one computer at a time. If either one of those numbers doens't match the ones in our database the user is givven an internal IP and will be redirected to a special page from where he can register his new equipment. -- Casper Gielen [EMAIL PROTECTED], [EMAIL PROTECTED] -- "After you install Windows XP, you have the option to create user accounts.
