Use different IP range for client networks and OLSR network. May be
you can try the following.<br>
<br>
(192.168.1.2/24) (192.168.1.1/24)
(192.168.2.1/24) (192.168.2.2/24)<br>
C1<------------>
R1<--------------->R2<------------------>R3<----------->C2
<br>
(10.0.0.1/8) (10.0.0.2/8)
(10.0.0.3/8)<br>

* The HNA should be configured only on the Routers where clients are
connected. So, on R2, you should not configure HNA.<br>
<br>
* The HNA entries should reflect the client networks the router
connected to. So, in the above case,<br>
<br>
On R1,<br>
<br>
Hna4 {<br>
192.168.1.0 255.255.255.0<br>
}<br>
<br>
On R3,<br>
<br>
Hna4 {<br>
192.168.2.0 255.255.255.0<br>
}<br>
<br>
Restart the OLSR daemon on R1 and R3 after making the configuration
changes.<br>

Hi,<br>
<br>
based on your questions I added some more text
to the coming OLSR<br>
wiki... can you have a look if you think they
are<br>
useful/understandable?<br>

Excellent resources! Thanks.<br>

If you have the topology like this, you can use the
following instructions to make the clients to ping
each other. (Just ensure that you don't have any
iptables rules which interfere the traffic)<br>
<br>
<a moz-do-not-send="true"
href="http://192.168.1.0/24" target="_blank">192.168.1.0/24</a>
<a moz-do-not-send="true"
href="http://192.168.2.0/24" target="_blank">192.168.2.0/24</a><br>
C1 <------------> R1 <---> R2
<---> R3 <------------>C2<br>
.2 .1 .1
.2<br>
<br>
* On C1, add default route by executing the
following command<br>
<br>
ip route add default via 192.168.1.1<br>
<br>
* On C2, add default route by executing the
following command<br>
<br>
ip route add default via 192.168.2.1<br>
<br>
* On R1, add the HNA entry for <a
moz-do-not-send="true"
href="http://192.168.1.0/24" target="_blank">192.168.1.0/24</a>
network and restart the OLSR daemon. eg.,<br>
<br>
Hna4 {<br>
192.168.1.0 255.255.255.0<br>
}<br>
<br>
* On R2, add the HNA entry for <a
moz-do-not-send="true"
href="http://192.168.2.0/24" target="_blank">192.168.2.0/24</a>
network and restart the OLSR daemon. eg.,<br>
<br>
Hna4 {<br>
192.168.2.0 255.255.255.0<br>
}<br>
<br>
If everything goes fine, you can see routes to <a
moz-do-not-send="true"
href="http://192.168.1.0/24" target="_blank">192.168.1.0/24</a>,
<a moz-do-not-send="true"
href="http://192.168.2.0/24" target="_blank">192.168.2.0/24</a>
on all the routers (R1, R2, R3) using 'ip route'
command. Also, the clients (C1, C2) should be able
to ping each other.<br>

Good... I expected it to work, it was just

Do so... without the HNA the mesh routers
will not know about the<br>
IP/prefix of the attached clients of the
other routers!<br>

Should a route be set? Or does<br>
a<br>
default route exist?<br>
</blockquote>
You need a route from the client to their
local router to reach the<br>
rest of the mesh.<br>
<br>
The easiest option is a default route,
often distributed via DHCP...<br>
but in theory it would be enough to have a
route that is "wide" enough<br>
to contain all nodes in the mesh and
attached to the mesh.<br>
<br>
Default route does not work if one of your
clients has normal internet<br>
access (as an example).<br>
