John,

If the IOCs are not on the same IP subnet then you will need to add an IP route
to enable communication. There is a "ping" program supplied with tornado that can
be used to test IP communication at a primitive level. There is also information
concerning the configuration of EPICS for multi-subnet networks in the CA reference 
manual.
