Re: [B.A.T.M.A.N.] Problems with 0.3-beta rv963 and kmod-batgat

[Andreas Langer <an.langer@gmx.de>]

hi, 
i try to help....with batgat on the gateway please check the kernel log.....on 
the client side run batman with -d 3 and check if you get a virtual ip from 
the gateway, on a fresh restart it can be a delay until you get an ip.

your setup is :

wan with 192.168.111.1
gateway with 10.1.125.158, 192.168.111.74
node with 10.1.125.158
