Hi,
thanks for replying so fast. Unfortunately the reason isn't the blocked tcp-port, I tested it after I shutdown the firewall on each node with the same result as you can see above. Is there something else I can do?
Sure. You can debug this by using tcpdump. Use the following call to see the batman TCP and UDP gateway connections: tcpdump -ni <your_wifi_dev> port 1967 Best would be to send it to me, so that I can say a few words about your problem. :-)
