<br><font size=2 face="sans-serif">Thanks for your response, but I don't
think this fixes the problem. Why bother setting the Sending- and
ReceivingInterfaceAddr at all if you are going to get the address using
multicast loopback first? When I try this in my system with multicast enabled
on eth1 and eth0, the multicast loopback selects eth0 as the interface
and eth1 is not able to receive multicast data. The work around I
was using previously was to remove the multicast route from eth0, but in
my target, all NICs will have multicast enabled.</font><font size=3> <br>

<br><font size=3>Please solve this problem in the following way:</font>
<br>
<br><font size=3>GroupsockHelper.cpp line 105 (hopefully) - </font>
<br><font size=3>Function: setupDatagramSocket()</font>
<br><font size=3>- MAKE_SOCKADDR_IN(name, ReceivingInterfaceAddr, port.num());</font>
<br><font size=3>+ MAKE_SOCKADDR_IN(name, 0, port.num());</font>
<br>
<br><font size=3>The call to bind() allows all datagrams sent to the port
number to be received when the address = INADDR_ANY, as described here:
http://docs.hp.com/en/B9106-90013/IP.7P.html</font>
<br><font size=3>Binding to the ReceivingInterfaceAddr will allow unicast
data to be received on that port, but not multicast.</font>
