For everyone who has been misguided by the Arris SB8200 ethernet ports 1 and 2. You must purchase 2 IP from the ISP in order to use both interfaces. They can not be used as redunancy or at the same time with one IP address. I just got off the phone with Comcast and Arris over this as the Arris documentation did not state the purpose and requirements of these ports. I have create a case for them to update thier User Guide to ensure users are fully aware of this modem's funtionality. I will update this thread upon how Arris responds, and wheather they are a good manufacturer to buy products from. I will definitley broadcast to other forums where I see the same discrepancy of advertisement.
