Richard,
After rebooting a second time, eth1 isn't appearing in the routing tabel
any longer. The bridge seems to be working perfectly now!
However, I'm not able to retreive any DHCP offers.
I did some packet monitoring:

You can see the DHCP discovers, but nobody's answering

Do some packet monitoring on your wireless network to see if the DHCP
request is going out over the air... your problems stem from not
getting a DHCP address. At first I thought the address given to eth1
might be interfering with br0... but it seems not.

Okay, thnx!
Just a small question, I think I need to configure eth0
and eth1 to
manual? And not to DHCP?
Like this:
----------------------------------------
auto eth0
iface eth0 inet manual
auto eth1
iface eth1 inet manual
----------------------------------------
Ah - I missed that. Yes, you definitely want to set the member
interfaces to manual.
The thing I don't understand then: if you execute a
dhclient on br0,
how does br0 know the configuration of eth1? Because
there's a WPA2
configuration on it. Will it use that settings too while
bridging?
I'll be honest, I'm not sure - I've never done that with
wpa_supplicant and the debian tools. You might need to activate
wpa_supplicant in the pre-up for br0.
Check out the manpage for interfaces - it may have more details.
Ok, I made it myself a little easier by temporarly switching from
WPA2 to unsecure wireless networking.
I'm having the following configuration:
Code:
to lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
auto eth1
iface eth1 inet manual
wireless-essid ##MY-ESSID##
wireless-mode managed
auto br0
iface br0 inet dhcp
bridge_ports eth0, eth1
When I reboot, my interfaces are getting the following config:

I don't understand why eth1 is in my routing table. It shouldn't
be I guess?
Anybody some idea's?
