Hi,
I have two Asus wl500gp router, each with atheros(Atheros 5212) wlancards, running kamikaze 7.06; kernel ver.:2.6.19.2. and B.A.T.M.A.N. 0.2 rv451 (compability version 3) one of them has access to the internet. The one who has no internet connection, doesn't set a default route to the one who has. It only sets this routes:
it looks quite good so far. Blocked TCP is the most obvious reason that the tun device does not appear. the client tries to establish a TCP control channel (port 1967) to the gateway. If that connection attempt is ignored no default route will be set.
Regards, Marek
