HTH, Han I think you need to setup UDP broadcasting on the host, see this article: https://wiki-ext.aps.anl.gov/epics/index.php/How_to_Make_Channel_Access_Reach_Multiple_Soft_IOCs_on_a_Linux_Host
P.S.: For some reason, I had to manually set the "$addr" and "$bcast" variables, they were not working for me.
Best Regards,
Abdalla.

Subject: Multiple IOCs on a remote server
I’ve run into a problem I don’t understand. I’m running 2 IOCs on a machine in a different subnet. I can access the PVs by adding the remote machine’s IP address to my CA_ADDRESS_LIST. However I can only access the PVs from one of the IOCs - the IOC that I start second. Whichever IOC I start second. PVs from both are accessible from machines on the same subnet at the same time but only one set of PVs is accessible remotely. If I restart the first IOC then it becomes the accessible one and the other becomes inaccessible.
I’ve tried setting up a cagateway on the remote machine and the behavior is the same. Is there some trick to running multiple IOCs on a machine without which only one will respond to remote requests?
