Hello Kay,

The broadcast server reports: Last name requested by 10.1.1.1:56051, ​as one would expect. The WiFi address is not mentioned anywhere. The unicast server stays quiet, as shown by secs since last send.

Thanks,
Jure

Hi:

That's indeed strange! After you get that erroneous reply from the server...

Response:
{
 "ip.src": "192.168.11.237",
 "ip.dst": "10.1.1.1"
}

.. if you then check the server again, does it still report

epics> casr 5
Channel Access Server V4.13
No clients connected.
CAS-TCP server on 10.1.1.1:5064

.. or does the report now include 192.168....?
