I have a naïve question about configuring soft IOCs, of which we now have quite a number.  We have not been setting EPICS_CA_SERVER_PORT when running the soft IOCs, so we get the warning:

cas warning: Configured TCP port was unavailable.
cas warning: Using dynamically assigned TCP port 44160,
cas warning: but now two or more servers share the same UDP port.
cas warning: Depending on your IP kernel this server may not be
cas warning: reachable with UDP unicast (a host's IP in EPICS_CA_ADDR_LIST)

We have also realized that our soft IOCs are not visible from outside our beamline firewall.  We have opened up ports 5064 and 5065 in the beamline firewall, so we can access PVs from the wireless network, and that works for VME crates (and the first soft IOC on a given computer).

If we want to be able to access the soft IOCs from the wireless as well, is the following sufficient:

- Set each soft IOC to use a specific EPICS_CA_SERVER_PORT
- Open those ports in the firewall

Thanks,
Mark
