Today I tried batmand 0.3-beta rv791 (on ASUS-WL-500gPremium) and
noticed that batmand set definitly wrong ip rules
or has problems with alias-Interfaces and/or olsrd:

> root@17-3:~# ip addr show eth2
> 4: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc prio qlen 1000
>     link/ether 00:90:4b:7d:20:7a brd ff:ff:ff:ff:ff:ff
>     inet 104.61.17.3/8 brd 104.255.255.255 scope global eth2
>     inet 10.61.17.3/24 brd 10.61.17.255 scope global eth2

batmand delete olsr-rules and set "from 104.0.0.0/8 lookup 68"!?
