Hi John, I did a self-install kit and the tech took my external cable modem's MAC address to the shop. The address is in their database and I can confirm it with a peek at my account management screen. When you say you had them add your firewall's external NIC to their database, are you talking about the cable modem's MAC or NIC in your firewall, i.e., ep0 MAC?
