Thanks to all who responded so quickly.

I have worked around the problem by setting on the machine
EPICS_CA_AUTO_ADDR_LIST NO
EPICS_CA_ADDR_LIST 165.65.160.255 127.0.0.1

i.e. forcing it to use the broadcast address of our subnet, plus the
localhost.  I did this globally, i.e. for both clients and the IOC
server.  With those settings everything works as it should, i.e. local
clients can see local and remote PVs, remote clients can see the local
PVs.

I don't understand why this was necessary on this one machine, but not
others.

Mark
