<p><font face="Arial" size="2">Hi.</font></p>
<p><font face="Arial" size="2">In my project, I have three PC's (A , B and C). All of them are connected to each other through ad hoc (network <a href="http://10.1.1.0/" target="_blank">10.1.1.0</a>). B has two interfaces, one of them is
<a href="http://10.1.1.2/" target="_blank">10.1.1.2</a> and the other is ethernet <a href="http://192.168.1.175/" target="_blank">192.168.1.175</a></font></p>
<p><font face="Arial" size="2">I use OLSR as my routing protocol (switch 0.4.9), so that A and C can learn about <a href="http://192.168.1.0/" target="_blank">192.168.1.0</a>, and the OLSR interface shows that they learn about the routes correctly..
</font></p>
<p><font face="Arial" size="2">when i run my code, in which i use multicast sockets to join a group. The problem is that Node B does not recieve the multicast packets from its ad hoc neighbors, nor its multicast packets arrive to the ad hoc peers..Nodes A and C can send and recieve multicast packets from each other with no problems..Node B is only able to communicate with its adhoc peers when i disable the ethernet
interface.The following is the routing table of node B:</font> <br> <br></p>
