We have a monowall router behind DPC3941B, having trouble connecting to internet. Just purchased static IP and still can't get it to work. Comcast says everything looks good on their side. Modem is in Bridge Pass-through mode. On the monowall on WAN interface we tried entering static IP and gateway they gave us and still no go. Also, there is field for entering MAC address, I assume MAC address from the modem, we tried both of them as well.
If we connect desktop directly to the modem we get 169.x.x.x address not our static IP.
What else can we do to get it going?
