I'm trying to follow this, but it doesn't seem to square with my own
observations.

I've edited the following output to pertinent entries in context
(you don't need my TV's hostname/IP#).

west runs jessie, alum runs wheezy. jessie first:

Usage:

Note: the router does no DNS for the local network, only the
internet. Sorry I'm no longer running squeeze.

Cheers,
