Subject: PV gateway renders PVs as disconnected

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?

 

Best Regards,
