New subject: [B.A.T.M.A.N.] dns/routing/ issue (batman-adv mesh)

16 Jan 2013


      just like you ; i would like to have the mesh working even if a gateway 
dies.

cable connected clients on the client routers can access the wan
just not wirelessly connected.

You posted only one set of configurations, but it's not clear to me
whether that belongs to router 1 or 2.
Could you please repost (maybe in a pastebin.com link)
/etc/config/network
/etc/config/dhcp
/etc/config/wireless
for router 1
and the same, clearly labeled , for router 2

Problem:
router 1 clients (people with computers) can connect to it either with cable
or wirelessly and ping/access the wan. router 1 works well this way
router 1 can ping router 2 either on layer 2 or layer 3
router 2 can ping router 1 either on layer 2 or layer 3
router
clients (connected to router 2 via cable) are able to access and ping the
wan.
clients connected to router 2 wirelessly are NOT able to access the wan.
Seems a routing/dns issue

/etc/firewall contains openwrt default settings and i have questioned myself
if some rules need to be set there.
i tried this:
http://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2012-May/007131.html and no
success.
and read this which is somewhat related tp my issue too.
www.mail-archive.com/b.a.t.m.a.n@lists.open-mesh.org/msg07643.html
what am i missing ? iptables forward rules ?
