Yes, thanks, I had done that.
But I hadn't actually re-booted after adding PEERDNS=no to ifcfg-eth1.
It seems the mere change triggered the kernel to turn forwarding off.

Incidentally, I am running shorewall on this server with IP_FORWARDING=On .
I'm surprised this does not turn on kernel forwarding.
