You're welcome.

You're welcome although I've completely forgotten about that(!).

For information about slave(s):
ip l | grep master

AFAIk it's not possible.

Thanks (I'd added a more or less random gateway without considering
your netmask, sorry!).

Thanks for correcting my suggestion. I should've considered that you
don't have to defin e the bridge and its ports twice! Especially since
if you try to do so with ip or brctl, the "second" bridge creation
will fail.
