Hi Antonio,

This stage is working correctly in a lab. Every client can connect and
traffic is correctly routed and delivered. But I noticed the empty dat
table, so I think there's something that I'm not understanding or, at
least, that I could do it better. I'll try to explain what I want to
achieve, perhaps in that way I could be understood better.

I have a freeradius service controlling clients acces, one of the
attributes is the vlan-id, I'm using 802.1x. This part is quite easy I
think, but the reason why nodes haven't got any ip (but management IP,
which users can't achieve...) is not so easy.

1) I'm using dynamic vlan assignment. With this config, I just have to
change attribs in my radius server and create a new pool in my fw... I
haven't to configure anything in every node.

2) I thougt having nodes without IP and just forwarding traffic to the
main GW (the firewall) through batman-adv, not natting every client
traffic with the node IP. In that way, roaming is working very good. The
problem are stablished sessions, these sessions are lost jumping from a
node to any other. I think this problem is nearly related to the empty
DAT table, and empty DAT table problem is nearly related too the nodes
has no IP assigned. However, I'm not sure about this..

There is an image attached explaining bridges.

Thanks a lot.
Fernando.
