you mean "[interface=eth1]" ?

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

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