Yes, the 129.57.239.255 is the broad address for the 236 subnet. I have
tried using the actual address (129.57.236.20) also but neither seems
to open the flood gates of communication.
Any other thoughts?
Thanks in advance,
Sue

I have a curious problem concerning multi-subnet connectivity when
converting from Epics 3.13.2 to Epics 3.14.8.2. Using the same

I'm having difficulty understanding your subnet architecture; the IP
addresses you're using don't seem to match up — I think you just have
a typo in your EPICS_CA_ADDR_LIST setting.
From your description you have a heartbeat calc record on iocmc1
(129.57.236.20) which you would like to monitor from an ai record on
iocfb1 (129.57.230.101). In order for that link to work, the
EPICS_CA_ADDR_LIST on iocfb1 must include the 129.57.236.xxx subnet,
but you're pointing it to the 129.57.239.xxx subnet instead:
resource.def file for iocfb1
putenv ("EPICS_CA_AUTO_ADDR_LIST = YES")
putenv ("EPICS_CA_ADDR_LIST = 129.57.239.255")
