[B.A.T.M.A.N.] Need help bridging Regular AP to Batman

[André Pouliot]

Hi,

I'm trying to do a mesh network using the RaspberryPi and Batman. 

My problem is I'm using 2 wifi card on one raspberrypi one for batman and the other one for connecting to my wireless access point.

I already made my mesh network I can ping on layer 2 or 3 between 2 raspberrypi. When connecting the Ethernet cable(on the raspberry with 2 wifi dongle) I can use the bridge to ping toward the internet. But when I disconnect the cable I can't ping internet anymore.

I already verified my batman interface and my bridge both seem to work

The AP is connected on wlan1, wlan1 doesn't have an IP address assigned to it. The AP is configured with WPA2. When trying to assign a address using dhclient to the bridge interface the system can't seem to find a way and the command is waiting.

If I want to connected my batman network to a standard wifi AP do I need to use a bridge or the functionality exist with batman? 

If it's with the bridge how can it work?

I'm putting the output of a few command at the end of the email. If you want anything else It will be my pleasure to send it.

You are using your second non-mesh WiFi card (wlan 1) in client mode, right? 
You can't include client mode into a bridge, because a WiFi client (normally) 
does not support bridging. Actually your system should prevent it ...

If you want to connect your Raspi to your WiFi AP, I see the following 
options:
 * Use Layer 3 Routing and keep the WiFi Client
 * Configure your Raspi as AP and your WiFi AP into client mode (if it supports 
that)
 * Connect one of your Raspis to Ethernet and don't use the WiFi AP at all.

Hope I got your question right .... :)

Cheers,
      Simon
