Hi Paul
The monitoring was ok but they were getting disconnected at some point. And I
think something weird happened is that some PCs getting disconnected PVs and
some PCs everything works fine.
Best Regards,
Abdalla.

Abdalla,
I had a similar problem with some CA clients back in 2000 (titled CA Server
disconnects) so this is a longshot...
Back then I had a repeatable time-to-disconnect of 2 hours, 11 minutes, and 15
seconds; could it be due to no CA activity from your IOC to the client side of
the gateway. Are all client-monitored values on the affected IOC never changing
for long periods?

Hi
We are running the gateway on a virtual server with 1 network interface,
this server can see all the different LANs (office, machine, beamlines,
etc.) through routing rules and access lists done by the IT group. When the
gateway is running, after a while entire IOCs gets disconnected. We are
running the gateway with no arguments but in the .bashrc file we are
defining EPICS_CA_ADDR_LIST having the IP address for the gateway to look at
(Not all IOCs). This behavior happened when having all IOCs or some of them
in the address list.
I came upon this video from APS https://www.youtube.com/watch?v=Y5Ge89Y4d1E
In which, as I understood, they have multiple gateways running on the server
with each gateway connects one network interfaces together to the other
interfaces. So my questions are:
1.What is happening with our setup? Some CA loops happens at some point?
2.Is having a network interface per VLAN optional or recommended?
