I've had it switched off over the last week whilst I've been trying to
sort this out, but forgot tonight.  It must be the combination of
setting multicast_querier and stopping the firewall that is needed.  I
can now see:

which is what I wanted.

Thank you very much, I can go on to build the filesystem now.
