Conbee 2 --> gateway names differ at Windows and raspberry

Annother behaviour I do not understand. I put the stick from the raspberry (192.168.178.172) to the Windows PC (192.168.178.32) and type in 192.168.178.32/pwa then following happens:
Ip on the GUI is 192.168.178.172, in the browser 192.168.178.32, the sensors are the same as plugged in the raspberry, the firmware info says: not conntected, seams not reasonable.
