If you control the router/DNS/DHCP, then the best move is to
drop NetworkManager and use /etc/network/interfaces:

bridge_ports enp3s0
address 192.168.2.3
netmask 255.255.255.0
gateway 192.168.2.1
I tried what you suggested, and I have a weird result. It works, but I
get an error message.
# ip -brief -family inet address show
lo UNKNOWN 127.0.0.1/8
br0 UP 192.168.2.3/24
On startup there was a little hiccup with a little red error instead
of a green OK. So I checked, and here it is:
# journalctl -p err
...
Jan 14 08:37:35 sandbox systemd[1]: Failed to start networking.service
- Raise network interfaces.
Any idea what's causing this error message ?

Hi Niki,
That seems completely normal. I have checked 5 different Debian 13
installations, and they display the same with this command. Never
thought about it, as everything works. Note that UNKNOWN doesn't mean
that the interface is down. If the lo interface had been down, the
computer probably wouldn't have been working anyway.
Best regards,
