[rescue] Putting an insecure machine on a network

Routing, maybe?  Do the 192.168.0.* boxes other than .20 know to route
10.10.10.[12] to 192.168.0.20?  If not, there's not much hope of
packets making it back to the laptop.

If the default route points to 192.168.0.1, it should be enough to
teach that machine to route 10.10.10.0/30 to 192.168.0.20.
