Use different IP range for client networks and OLSR network. May be you 
can try the following.

(192.168.1.2/24)   (192.168.1.1/24) (192.168.2.1/24)    (192.168.2.2/24)
         C1<------------> 
R1<--------------->R2<------------------>R3<----------->C2
                      (10.0.0.1/8)      (10.0.0.2/8) (10.0.0.3/8)

* The HNA should be configured only on the Routers where clients are 
connected. So, on R2, you should not configure HNA.

* The HNA entries should reflect the client networks the router 
connected to. So, in the above case,

On R1,

Hna4 {
     192.168.1.0      255.255.255.0
}

On R3,

Hna4 {
     192.168.2.0      255.255.255.0
}

Restart the OLSR daemon on R1 and R3 after making the configuration changes.
