No I have a router that works fine. It connects to the net and does
NAT., DNS caching and DHCP That all works. Behind that router are
two machines. Neither of those machines needs to do any routing,
except to talk to their local network and know where the gateway is.
Nor do they need to do NAT; the router does that.
One connects to the router just fine; I'm sending this message
from it. The other one fails. I do not need anything fancy here;
I just need to get that machine's ethernet interface working.
