ipbus software on different devices

[Angeloloi19]

dear all,
i'm using the ipbus to control a DAQ system for a small R&D tracker. At the moment on the same network we have two prototypes active with same fpga (kc705). So what I did is to assign on the firmware two different IPs (192.168.1.3/4) and the mac address is changed by setting the dipswitch on 0101 on the first one and 0000 on the second one. The problem is that the second one does not comunicate with the software and the classic Warning with "Closing UDP socket for URI ... since deadline has passed".

Do you have any recommendations on how to set mac and ip addresses on different devices?

Thanks in advance
