[B.A.T.M.A.N.] Problems with internet connection in a mesh-network, (and dhcp and wireless access)

Hi all

I wrote recently about problems with our batman-adv mesh implementation in a development proyect in Peru:

https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2012-August/007820.html

Now we are having problems again. Our mesh-network are formed with Ubiquiti nanostation M5 nodes running OpenWRT(10.03.x, r32751)+ Batman-adv 2.6.32. In one of the nodes, the wan gate is connected with Public IP to internet and I can access to internet from there.

But from a laptop(without batman-adv), I can make ping to all the nodes of the mesh, but i can't make ping to 8.8.8.8 neither the Ip public gateway. However, I can make ping to my Ip Public, in the interface wan of my gateway node.

What am I doing wrong? I have tried to write static routes, but I think that the problem is about the mesh-bridge. Is it beacuse of i need do NAT?

All the nodes of the mesh can see themselves, and I set the node with the gateway to internet like the gateway of the mesh, but it does not work.

Any help or comment?

That is my /etc/rc.local and /etc/config/network in the gateway node:

/etc/rc.local

wifi up ifconfig wlan0 mtu 1528 batctl if add wlan0 ifconfig wlan0 up ifconfig bat0 up brctl addbr mesh-bridge brctl addif mesh-bridge eth0 brctl addif mesh-bridge bat0 ifconfig eth0 up ifconfig bat0 up ifconfig mesh-bridge inet 1.1.1.1 netmask 255.255.255.0 ifconfig mesh-bridge up exit 0

/etc/config/network

config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0'

config 'interface' 'lan' option 'ifname' 'eth0' option 'proto' 'static' option 'ipaddr' '192.168.1.2' option 'netmask' '255.255.255.0'

config 'interface' 'wan' option 'ifname' 'eth1' option 'proto' 'static' option 'ipaddr' my Ip public option 'netmask' '255.255.255.192' option 'gateway' my ip public gateway option 'dns' '8.8.8.8'

config 'route'

And some offtopic questions...

What should i do for permit to others laptops without batman-adv can connect by wireless to the mesh, make another wlan interface with another ssid in ap mode and add it to the mesh-bridge?

With ethernet all works fine, the problem is without wire... Should I check the dhcp in order to the laptops can connect directly to the mesh network? How could I configurate it?

Thanks you very much and regards
