Experimental Physics and Industrial Control System

Dear EPICS experts,
I would like to run one EPICS IOC on a Linux system configured with
two Ethernet interfaces connected to
two different networks. But I would like the IOC to respond to the
requests to only one of the interfaces,
and send the data using the same interface. Basically, I would like
EPICS IOC not to interfere with
the main traffic going through the other Ethernet port. Can this be
done? I know it can be done using a virtual
machine, but I would like to avoid doing it and consuming extra
resources since these are VME CPUs.
I tried running an IOC that I built using R3-14-12-3, and when I set
EPICS_CAS_INTF_ADDR_LIST
the IOC still responds to the requests sent to any of the two
interfaces. Actually, the CA manual page says that
"In R3.14 and previous releases the CA server employed by
iocCore does not
implement this feature."
Is this feature going to be implemented for IOCs in the near-future
releases (3-15 for instance)? And another
question is if eventually the IOC only responds to the requests
addressed to only one of its interfaces, will it
also transmit the data using that interface or the data will be
routed considering both Ethernet interfaces?
