Thanks Serge. I have changed static to manual and ... nothing happens. See:
auto intprodif
iface intprodif inet manual
bridge_stp off
bridge_fd 9
bridge_hello 2
bridge_maxage 12
.. and when I execute "ifup intprodif":
car...@silmaril:~$ sudo ifup intprodif
Restarting openntpd: ntpd.
ssh stop/waiting
ssh start/running, process 8467
.. doesn't returns any error, but if I execute "brctl show":
car...@silmaril:~$ brctl show
bridge name bridge id STP enabled interfaces
car...@silmaril:~$
... bridge doesn't exists ... Any idea???
