I had a hell of a time getting that to work.
The new DSL modem / router is now operating as a bridge, meaning that it's just a dumb modem and not doing any routing. It has a management IP of 10.0.0.1 but of course it's on the internet-facing side of our gateway so the easiest way to get to that is to plug into the dsl modem/router with ethernet, set your own IP to e.g. 10.0.0.2 and open a web browser to 10.0.0.1
The login info is in /root/passwords on space.local
The wifi on the dsl modem/router has been turned off.
I don't know if we have a static IP from LMI, but this is our IP for now:
142.254.119.218
The LMI DCHP server was willing to give out one IP for the modem/router, and then one IP to my laptop during testing, and then it would not give out any more IP leases to any other machines even after explicitly releasing the lease from my laptop. Setting a static IP in the same range didn't even work. I had to change the MAC address on the eth1 network interface on space.local to my laptop's ethernet MAC address. I put that in /etc/network/interfaces for now, but I'll call up LMI when I have a moment and see if we can sort out a static IP.
