But with this configuration, the local network does not work.
Probably because the bridge port is set in 10.42.0.0 (Automatic DHCP) and not in 10.40.0.0.
If it is correct, I need to set it static
10.40.0.0 255.255.255.0  what about the Gateway and the DNS ?

Note also that the IP address of enp0s20f0u11 (USB Ethernet) has also changed.
Should I set it static ?
192.168.1.166/24  Gateway 192.168.1.1 ? DNS 192.168.1.1 ?

Thanks
