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.
http://dpaste.com/hold/879202/

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

 Scenario:
 router 1 is the internet gateway
 router 2 is a client router of that gateway
 Both routers in vap mode with 2 diff ssid's
 one dhcp pool for 'lan'

 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 ?
