Maybe it is a setting, i have searched everywhere, but this is really mysterious

take a linux, configure this kind

eth0: 192.168.10.200 / 255.255.255.0
eth1: 192.168.10.201 / 255.255.255.0

Both Interfaces are "real ethernet cards" and are connected to same switch

if you take now a 3'rd machine, and do a
