[Bridge] wlan0 will not be automatically added to br0

[Markus Feldmann <feldmann_markus@gmx.de>]

Hi All,

i want my wlan0 added automatically to br0 on my Debian Squeeze Server. 
At the moment the ports eth[1-3] are running over br0. I am using kernel 
3.2.9. The port eth0 is only for internet. eth[1-3] are for my local 
network at home. When i manually add wlan0 to br0 i can built up a 
communication between my laptop and my server. Therfore i execute the 
command <brctl addif br0 wlan0> on my server.

Here are some configs:
/etc/network/interfaces
auto lo
iface lo inet loopback

auto br0
iface br0 inet static
     address 192.168.0.186
     netmask 255.255.255.0
     broadcast 192.168.0.255
     bridge_ports eth1 eth2 eth3 wlan0
     bridge_ageing 300
     bridge_fd 1

# Mapping to DSL- oder DHCP-Router
mapping eth0
     ...

<brctl showstp br0> only shows the ports eth[1-3] when i try to add 
wlan0 with </etc/network/interfaces> start-script. Any idea?
