vmbr0 problem changing interface

[diegargon]

hello

I have a (i think) strange problem.

Today i change the iface of the vmbr0 but seems not work (i reboot) if i disconnect the cable from old interface i can't connect ,


The old interface is enp3s0, the new one is enx3c18a0d4e038

I only can connect if the ens3s0 cable is connected

If i remove the cable from enx3c18a0d4e038 interface i still can connect using 192.168.1.2
if i remove the cable from enp3s0 i can't connect neither using 192.168.1.2 or .52
