First of all, thanks very much for your advice.
I found in the end - probably due to something you said -
that the problem was entirely due to the fact that
I had omitted the line

#INTERFACE              SOURCE          ADDRESS         PROTO   PORT(S)
eth0                    eth1

in /etc/shorewall/masq .
Since I put it in, and re-started shorewall, everything is working fine.

Nb My iptables data presumably all comes from shorewall.
I see this address is mentioned in shorewall
(in /usr/share/doc/shorewall*/Samples/two-interfaces/ , which I followed).
Isn't it used in some way if one's internet connection is down?

Actually, I had to stop NM with this OS,
and use the network service instead.
I'm not sure why.
But the network service seems to work fine,
and this is only a backup OS, so NM's failure doesn't really matter.
