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.

Subject: Re: PV gateway renders PVs as disconnected
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?
