If you set the EPICS_CA_ADDR_LIST to the broadcast address then you must also set EPICS_CA_AUTO_ADDR_LIST=NO. That is why you are getting these warnings, because these broadcast addresses were already being used because EPICS_CA_AUTO_ADDR_LIST was defaulting to YES.
Warning: Duplicate EPICS CA Address list entry "192.168.1.255:5064" discarded
Warning: Duplicate EPICS CA Address list entry "130.20.49.255:5064" discarded
