Hi,
I am testing out batman 0.3-beta rv963 with openwrt-trunk (r10219) .
I could get the expected results when i am using tun instead of kmod-batgat .
but when i use kmod-batgat even tho the tunnel gate0 is established the
routing rules and firewall is same as with kmod-tun i cant get traffic thru gate0
My Setup:
---- Wired
- - - - WiFi
192.168.111.1-----(WAN)-192.168.111.74(Gateway)10.1.125.158 - - - - - - 10-1-125-158 (Node2)
With kmod-batgat:

batgat 10976 1

Also at times ip rules dont appear on node and i have to restart batmand to get the network working.
