Todd,
Thank you for the information, the Level 2 support guy never mention that I could do that. I will check on it.

I called Cox and they swapped it for a separate phone and separate modem. no problem:) On Sat, Feb 28, 2015 at 5:33 PM, David Demland <[email protected]> wrote: Does anyone know much about a Cisco DPQ3212 Cable Modem? Cox put it in a few months ago and I did not think much about it since every was working on my network. However recently I had to log onto a VPN for a customer and I could not.

There is no username and password to get to the status screen; but the I cannot find an administrator login for the modem. Looking at all the output it seems clear that the modem is doing a NAT, of private IP space 10.32.4.1, which would be a problem. I need to turn off the NAT so that everything works. That is the issue, I can find nothing on line about this and I have talk to Cox level two support and they have no idea. The think that confuses me most is that I am getting a valid public IP on my Router (I can even VPN in into my home network), but the traceroute never shows my packets going through the public IP. Does any know how to login into this modem and turn off NAT?
