Hello everybody, I did many tests, and it seems that something is wrong. I tested on Ubuntu 22.04, where the network management is different. So I moved to a DEBIAN 11 but it is still not working. At the end I can ping the ethernet port (in this note the eth1: 192.168.0.50), I can ping the bridge (br0: 192.168.0.51 or 192.168.0.99) but I cannot ping the ethercat device. Could someone explain to me which are the interfaces involved and how to place the right IP addresses. Thank you Maurizio
