You were right as I was getting some other outputs in #ip rule<br>

I changed the olsrd/conf file and commented the RtTable entries to<br>
select kernel default table by olsrd.<br>
Now in setup PC1<-------->(eth0)PC2(eth1)<----------->PC3, We are<br>
able to ping PC1 frpm PC3 and vice-versa.<br>
Now I have to run a vedio streaming from PC1 to PC3. Do you have any<br>
idea to do it? </blockquote><div>use any software you like,.. <br>.<br></div><div>or the maybe easiest solution:</div><div>attach an ip webcam (with its own http server) on one olsr node, and announce the ip of the webcam via hna (olsr config-option) to the other nodes</div>

<br>
this means that pc3 searches for its (possible wrong) Default gateway<br>
which it only does if there no olsr routes which mach better than the<br>
default route<br>

looks correct, but as it doens`t work,...<br>
<br>
check (for exampl eon pc3) what<br>
#ip route<br>
(should contain routes to the other olsr routers) and #ip rule (should<br>
be only 3 lines) print out<br>
<br>
<br>
and pls leave the bmf plugin away (at least for the moment)<br>
<br>
<br>
if ip route doen`s print the expected routes configure httpinfo (or<br>
txtinfo), and check there if the links get symmetric, and if the olsr<br>
wants to create routes (i mean if it list routes there)<br>
