Como configuro uma rede ponte ?

# You don't usually need to touch this file at all, the full configuration
# of the bridge can be done in a standard way on /etc/network/interfaces.
# Have a look at /usr/share/doc/bridge-utils/README.Debian if you want
# more info about the way on wich a bridge is set up on Debian.

O exemplo interfaces vem com eth0 definido - estou usando o wi-fi. Enquanto há uma porta ethernet, não está em uso.
Não há seção The primary network interface para o arquivo interface acima. Aqui está a informação de rede:

É wlx74da3889c88b , que representa a conexão wi-fi com o roteador, sendo o gateway padrão 192.168.1.1 . Use wlx74da3889c88b para a "interface de rede principal"?
Talvez simplesmente não funcione com wi-fi.
