<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Often Multicast sockets are set up to “not
loopback”. This means that any traffic sent from the local computer is
not received at the local computer again. This is typically true of
bridges.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I do not think that you need to set up two
separate cards to listen in to multicast and unicast at the same time.
You can only set up one unicast socket listening on a particular port, but you
can usually set up any number of multicast sockets listening on the same port
as the unicast socket.<o:p></o:p></span></font></p>
