[B.A.T.M.A.N.] Batman problem with tun0

[Anton Gillert]

I have following problem:
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:

Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
192.168.33.23   0.0.0.0         255.255.255.255 UH    0      0        0

0      0        0 tun0
how can I fix it, or what did I wrong? here my are settings

On the router with the internet connection:

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.

Marek
