Hi,
I use batman advanced ("# batctl o" says "B.A.T.M.A.N. adv 0.2.1-beta r1578") on OpenWrt trunk and I have the following problem:
I have a wlan meshnetwork in ahdemo mode which uses batman. The meshnetwork is used by clients without batman and therefore I have another network on the same wifi device in ad mode which is bridged with bat0. The bridge is in the network 10.18.1.0/24.
I think its like described in http://www.open-mesh.org/wiki/batman-adv-quick- start-guide
Yes, this configuration looks quite good already if I didn't miss anything and if you're having wifi cards with an atheros chip. What kind of devices are you using?
I use Fonera and Dlink Dir300 wich have a atheros chip inside.
The problem is, that I have a vpn network on tap0 (10.18.0.0/24) and I dont know how I can link this two networks/interfaces to each other with batman. I tried to assign tap0 to batman, but this doesnt work.
I want to be able to ping hosts that uses batman in the vpn and in the wlan network. How can I do this?
Ok, now I have some more questions already :). What do you want to gain with this vpn exactly, merging a couple of mesh clouds or getting the network behind the vpn into the mesh? What is creating this vpn right now, how are the two sites connected with each other (over network identified with 'lan' I guess?). Does pinging inside of the vpn itself without any mesh work?
Yes the vpn network is created over lan. The VPN is created by an central openvpn server in tap mode and ping inside the vpn works without batman. The VPN is used to connect several mesh clouds which can´t sea each other wireless. Ping from one Mesh device to another meshdevice on the other side of the vpn tunnel works. I think because they are both in the 10.18.1.0/24 network.
But the devices which are connected to the vpn network have a ip from 10.18.0.0/24 and should also be reachable from the 10.18.1.0/24 (wlan) network and this doesnt work so far. I can ping the mac adresses inside the vpn from the wlan network with batctl but not with normal ipv4 ping.
From the configuration now, it looks like you're having another batman-adv on the other side of the vpn as you've assigned tap0 to batman. So keep in mind that the recipient on the other side of the tunnel will get batman-adv ethernet frames only which encapsulate the payload - there has to be a batman-adv on the other side to unwrap the IP packets again. And if there is a batman-adv on the other side of the tunnel, make sure the vpn itself is transporting whole ethernet frames and not only ip packets (in tinc this is "switched" mode for instance or in OpenVPN having "dev tap" and not "dev tun").
Yes the setup is like you describe it.
I just give you an output of my devices on a Dir300 connected to vpn and wlan. Maybe this can be usefull for you.
