John,
The address of your router ( Gateway ) is 10.0.1.1 and things are as they should be. Your ROCK gets it address ( 10.0.1.64 ) from your router via DHCP and DHCP also hands out your router’s address as the DNS server address for everything on your network. This allows you to update the DNS servers on your router as you have done and every device on your network will automatically end up using them without any reconfiguration on your part.
