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:

                                                      eth1

My routing table looks like this:

Code:

But I'm not able to ping my router ...

Code:

--- 192.168.1.1 ping statistics ---
5 packets transmitted, 0 received, +3 errors, 100% packet loss, time 4018ms

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