Oh.. ok. I haven't used openwrt. Let us hope for help from someone
else.<br>

</span> * Check the routing entries throughout the path

everyone,<br>
I have configured 3 routers r1 r2 and
laptop with olsrd on adhoc mode. The
topology is as shown below.<br>
r1 <--> r2 <--> laptop<br>
r1 can see r2 but not laptop and r2 can
see both. When i started olsrd r1 could
not ping laptop but it could ping r2 and
same with laptop. I even enabled
forwarding on r2 but still with the same
results. So Is there any way to solve
this??<br>

Is this problem similar to the one you have
posted and resolved earlier (pl. see the
following URL)?<br>

Did you try the same debugging steps suggested
then by Henning?<br>
