I am looking for a full user manual for the DG3450 Digital Gateway Modem -- which my cable provider/ISP (Sparklight) just installed in my house. I have searched every nook and cranny of the ARRIS web site and there is no reference to the model number. On the web there is exists draft copies of a User Guide but it does not cover topics like Port Forwarding or DynamicDNS setup. Someone at ARRIS must know about this product.
