Hi Antonio, thanks for your answer.

I explain a bit more my stage... I have a server with DHCP that is the
default gateway of all BATMAN nodes and clients, and BATMAN gateways are
connected to it fisically. For roamming, I won't have IPs of VLANs in
BATMAN nodes and all default gateways of VLANs are configured in the FW.

Clients connects to wlan1.X, but that interface is created by hostapd
when radius allows access to the network of that client (default dynamic
vlan behaviour). As hostapd creates this interface on demand and
destroys it when is killed, I can't add wlan1.X to the bridge (br0).
However, there is arp traffic on wlan1.

Greetings.
Fernando
