Update in case anyone else comes across this, he did find the reason it
wasn't working and Shaw support was misinterpreting the problem. It turns
out that the way the modem behaves is the first two MAC addresses that it
sees are automatically allocated the two WAN IP addresses, even if that MAC
is not running a dhcp client. So his third machine he was using to access
the 10.0.0.1 admin interface was being allocated one of the WAN IP
addresses, even though there was no DHCP client on that machine.
