Hi Gustin,
thank you.
In my example I do NOT have a bridge interface. I don't use brctl at
all, so I think it's ok for wlan0 to have the IP address (since it
works).
For the sake of learning, I tried your solution but I didn't manage to
make it work. The bridge I create with brctl never gets an IP from
DHCP. If you have time to help me further, I can try again and learn
how to do it.
In my first reply to your post (On Fri, Feb 3, 2012 at 2:30 AM) I
explained the problem I faced in trying to implement your solution.
Maybe the bridge only works with a static IP?
cheers,
alfonso
