Hi Bhavna,

It seems to me that the setup you describe should work without setting the EPICS environment variables at all. The IOC on B should make its PVs available on both subnets. 

At the IOC prompt on B type epicsPrtEnvParams and send the output. On C type “set” and send the results for any environment variables starting with EPICS.

Are the subnet masks all set correctly? It looks like they should be 255.255.255.0.
