Oooops! It just occurred to me that you're not trying to
DIAL into this thing. That is what I was giving you instruction for. If you're not dialing in, forget about the 10.10.14.0 network.
So, to access via IP... I wouldn't recommend a Public IP address on the BCM itself. Your best bet is to access through a VPN tunnel. And, as luck would have it, you've got a 2.0 version so VPN clients are supported. If you would rather not configure a VPN, use the dial-up method.
As for disabling the router (you pay extra for that you know

). Just disable DHCP, remove any conflicting addressing, and unplug the WAN port.
