hostapd + bridge

Sat Oct 8 14:56:47 PDT 2005

Hi,

I am using a Debian based system called "c't-Debian-Server" with an integrated 
IPCop firewall running in UML mode (User mode linux). The phsical network 
interfaces are connected to IPcop using tun/tap devices. IPCop's "blue" 
interface (for WLAN) is connected to tap2 with IP 192.168.254.1 within the 
UML. Now I want to set up a WLAN-AP with hostapd and connect it to br2. 
Without bridging it works just fine with hostapd and WPA, but after adding my 
wlan-interface to the bridge and setting up the bridge there is no connection 
anymore. Are there any ideas out there? 

Here is what I've done:

> brctl addif br2 ath0
> ifconfig br2 192.168.254.100

> brctl show
br0             8000.0040f4cdaa34       no		eth2
					tap0
br1             8000.00e07dc449fa       no		eth1
					tap1
br2             8000.ee254d91a3d9      no		ath0
					tap2
br3             8000.fa63a7d1bcde       no		tap3

> ./hostapd /etc/hostapd/hostapd.conf
