Please don't forget that olsrd2 only installs routes on the mesh<br>
routers... so you need some kind of route on the devices attached to<br>
the "local ethernet" back to the router, e.g. a default route.<br>

<br>
maybe you could just post the output of "ip route" from all 4 devices<br>
(two mesh routers and two attached devices)?<br>
