Are you talking about outgoing packets to a multicast address? I think
that there may be some bugs in that area since the addresses are limited
and choosing an outgoing address becomes an issue and it will only send
it out on one address. I'm not sure if it's possible to set up a server
(at least not easily) to send via different interfaces.
To do this correctly you need to be able to set up a different multicast
address to use and associate it with a particular server address for
each interface. The only way that I can think of to accomplish this is
to be able to specify a specific binding address in the config file. We
would have to add that as an optional parameter to the broadcast directive.
