Please also consider reading

    https://wiki-ext.aps.anl.gov/epics/index.php/How_to_Make_Channel_Access_Reach_Multiple_Soft_IOCs_on_a_Linux_Host

which explains exactly that, including solutions that do not require any Channel Access client configuration.

It should work fine to simply not define EPICS_CA_ADDR_LIST at all on either the client or server machine, as long as they are both on the same subnet.

Hi:

> I defined the EPICS_CA_ADDR_LIST=127.0.0.1
That's your problem.
127.0.0.1 is not a broadcast address.

Read https://wiki-ext.aps.anl.gov/epics/index.php/How_to_Configure_Channel_Access, and find the broadcast address of the host which runs your IOCs.
Hint: It's an IP address that tends to end in 255.
